Perpetual Grow Among Other Things!

Mostly there not not completely...

Ok so Time to throw up a good update!

Things are moving along well but starting to have some issue's.


For one the new grow rooms are taking some time to get dialed in. I am almost there. I have two plants in flower that are very close to harvest and they are pungent. So I switched some more things around with the layout of the fans and filters and solved it. I don't think there will be an odor issue at all going forward. Constant filter mode and separate fans to vent out heat is the answer. one charcoal filter in flower scrubbing and the room temp vents into veg and that room runs a scrubber and that room temp based vents out to basement. No odor at all directly outside room. Solved... Til I have 6 in flower some day.


So second issue was a few days ago I had cold issues and then it became heat issue's. So HPS has to run at 75% right now. I do want another LED same as what I have and i hope between the two and the Small 400W heater i will be all set (ditch the HPS again) But I will have to wait on it for now. Also once the 130 degree air compressor is out of the room I will be all set. I could actually do it now. I am running one tub in top feed so I can't shut down the LED and soon the compressor wont be used. Just a small one in the big res. As I harvest the DCC and BK new plants won't be DWC but will go on top feed. It will be the fun for the foreseeable future.


So here is the 20 gallon Botanicare tub.

IMGP10571.JPG



This is the pump set up. I have a 90 deg adapter drilled on the end of the hose for the intake. It will drink pretty much as long as the res isn't totally empty.


IMGP10581.JPG


I had to build a stand as it needs to be below the gravity feed from the tubs so here it is all installed with the TW clone in it.......

IMGP10661.JPG


Totally not pleased with the tubing etc yet. and Two tubs are not hooked up yet. I'll redo it all then. I'll need to build a similar shelf on the other side but will need to harvest first to clear the space...

These two are over there!

IMGP10632.JPG


Pics of these are all in lights out so I sucked at it...

IMGP10642.JPG
IMGP10612.JPG
IMGP10602.JPG
IMGP10591.JPG


Both have been in flower 58 days and should be flushed very soon. But I am going to wait. The DCC is just swelling like crazy and I am purposefully running it longer than normal for me at least. The BK just hasnt ever taken off... It went into flower way too early I guess. Or a week or so. I'll just let it run its course and cut it down a week or two after the DCC. As long as they don't hermie but I have been watching them and they just aren't done. They are starting to have some leaf issues but I am not sure why they both have been on a steady nute schedule. Some plant shuffling etc but never anything serious. I missed one cal mag supplement feeding once. so not sure. BUT they did go from LED for 6 weeks to HPS for 1-2 now. I will chop soon so no biggie. I actually think the roots outgrew the air stone as a possible too... 10 gallon tubs..Don't let the BK fool yah the root mass is enormous and the air get eaten by the roots if that makes sense.. So I Filled them a little less in the last res swap yesterday. Top feed will change all this anyway...


So over in Veg it is a whole different game. All top feed at this point. Plant definitely liked the MHS better than the T5 but oh well. This T5 will get an upgrade as well but I may stick with similar just bigger and not go LED. I spend too much time in there to want to go LED in there. It still may happen though. We'll see that road then.


IMGP10682.JPG
IMGP10701.JPG


This is the most of it.... I am starting to see some deficiencies on some of them. I am new to top feed so and all these where in DWC to start with so I expect them to need to the change and I will have to be gentle and dial it in cautiously. So far so good but some are taking a bigger hit like the ACDC.

IMGP10743.JPG


Lost some lower leaves but it did go srom soil to DWC to Top Feed so as long as it just takes a small smack and the center top still looks lush. So I am just watching it close.

So the latest two members to complete my initial seed order are popped (5 Afghani non-fem ..meh)

IMGP10711.JPG


Yup 1/2 inch roots directly into hydroton under 750 ppm ... ROFL! The are like yah Biatch! Lovin it!

They grew fast so far in 36 hours of top feed .. not kidding. I let them sit in the cotton pill bottles i popped them in a tiny bit linger cause i knew they where going straight in....

So without further adieu.

Royal Queen Sour Diesel Feminised Seeds Info


The world famous Sour Diesel is now available in feminised seed from Royal Queen Seeds. We are proud to add this fine cannabis strain to our selection. This might be one of the most famous strains of cannabis on the planet; and maybe one of the strongest.

Like many of the best cannabis strains coming out these days, Sour Diesel comes straight from California. It is a favourite with many smokers and growers. These powerful American genetics will grow well indoors around the world; outdoors, on the other hand, they need a warm climate, similar to California or Spain.

This is a mostly Sativa strain which shows in both its growth structure and the strong high effect it gives when consumed. The plant develops its resinous buds and powerful aroma over a 10-week flowering period. This is after a recommended 3-to-4 week vegetative period. These plants will grow to a height of around 100-130 cm, with some stretching during early flowering.

Sour Diesel is a very pungent, aromatic strain. Heavy chemical, herbal and sour flavours come from its glistening buds. When grown well, it will give yields of 450-600 grams per square metre. This is both a yield in quantity and quality, producing high-quality, resinous, aromatic buds. Full Diesel power!


Super long Flower 12 weeks!! Always was one of my Fav's Let see if it still will be ....


And!!!

Samsara Holy Grail 69 Feminised Seeds Info
On a whim, one of our breeders set about crossing our own Punky Lion with pure Haze genetics.
The result is a slightly taller plant than her progenitors, with very few leaves to trim and a fresh tropical Pina Colada taste that will amaze even the cannabis world's most hedonistic experts.
Covered in trichomes that produce a resin imparting a unique sense of controlled euphoria, this lady's best feature is the perfect balance between her Indica and Sativa characteristics.
Simply unique!


HG was a single freebie I got so we'll see if it is a keeper!

So the new veg room and plenty of flower room inspired me to pop the SD seeds and tie up the space. I Look forward to watching it grow!

Let's hope that all these do well as I am implementing the new top feeds as I go and hope I don't have too many growing pains with it. It really is a simple simple setup.

So this was a big update but that it how it goes these days. Less updates but alot more content. Hope everyone had safe holidays and as always never hesitate to comment as I can always use some help.

You put in some serious work there my friend! I really hope it all pays off for you FE. I am having temp issues as well. It is too cold in my grow area. I am going to have to get some heat in there. Have a good one and look forward to seeing some great things. :)
 
Very nice Comrade!

You have it all complete now.

Oh and I figured out why I had to give up on DWC and all that - no hydroton around where I live :rollingeyes:

Going to give ebb and flow a try and see what happens

yah I have been thinking about it comrade and no hydroton sucks! There isnt a lot of options to replace it. But there has to be something that can be tweaked to work. Like coco with perelite or something


Still learning this drip thing but really like it.. popped a couple seeds and basically threw them in the hydroton under drip and they are growing amazing. No rockwool nothing.. But still learning timing and such.. gettin there...
 
Cleaning things up....

Harvest time!

Delicious Cheese Candy and Bubba Kush hanging!

Ok so good and bad.. But lets start with some final pics of them


The Bubba Kush

And the DCC

IMGP10781.JPG
IMGP1080.JPG
IMGP10791.JPG


Ok so the good is the DCC it is huge and nice buds.. but the BK and DCC had a couple f in nanners... So there is a couple seeded buds it looks like. I should have expected such as they had some cold times and shock of LED going to HPS in flower etc. So oh well.. Plenty of clones... I am pretty certain it was not the strains but my care. It really doesn't take much to stress them. The nute issue early and then the stupid idea to late defol must have been too much. The defol basically stopped the growth and stunted them. Late in flower they didnt get the development I hoped for. The DCC yield is large... BK is tiny... Oh well plenty for my consumption.

So here is the roots etc

IMGP1081.JPG

IMGP10831.JPG


The last one in flower for now is....

IMGP1091.JPG


A train Wreck that i have zero hopes for results.... It was in flower .. barely started to veg again and went right back into flower. It really should be in stretch but it hasn't yet.. not sure what will happen to it...

So I have now converted everything to drip... I have no more DWC anywhere... I will throw a plant into flower this weekend... Then another probably every 2 weeks or so for awhile. I want to make sure they get larger before they go to flower but the one this weekend will still be smaller. From there on out they will all be good. I got really out of sync with some plant issue's so I need to get back on schedule.



So I have quite an assortment going in Veg


IMGP10881.JPG
IMGP1090.JPG
IMGP1089.JPG


Alot of them are clones that came off the plants next to them. Serious toppings that became clones... ACDC finally has fresh roots popping out of the pot. I was worried for a bit.. The old roots rotted and the plant was wilting. It is still not looking great but roots white white mean it will look good soon. Sour Diesel and the Holy Grail seeds are getting taller daily. I am convinced, Top feed is excellent for seeds and clones when they first hit the hydroton. Top feeds them well ;) But I still have no idea on watering schedule. I have heard everything from 24-7 to 3 times a day 15 min with hydroton. I am running 15 on and 1.45 off in Veg i forget in flower but more often and off at lights off..


So new nutes this week and then fresh for all on a new plan.. I have the temps kinda reeled under control and humidity.. If I can get a better nute plan running with drip in flower the next run should be amazing with the new available space for them. I really want one more mars reflector for the other side then I will be essentially complete again in flower. I built the top feed shelf for the tubs on the other side so as I need the space I will just run the hoses over to it... If flow becomes and issue i have considered a new res for the other side as well .. but i like one res for flower one for Veg.. Easy as shit to keep up on...

Veg still needs a huge T5 light... I want an 8 bulb 4 footer ;)

So buds drying.. report to come... flower will be kinda quiet for awhile... 4 weeks on the TW but it will be bushy and tiny... as long as it doesnt start nannering or herming then I'll let it run and just add plants as I go...

Thats about it i guess


Thanks for stopping by....

Take a look!!! J/k no pictures today....

Ok so a little update ...

So I had been on the big nute debate.... So today I bought the whole Cutting edge Solutions line,,... I know non sponsor .. sorry... My only other one I considered is a non sponsor as well so I won't mention them. Maybe I can get the call rolling on CES becoming a sponsor... Anywho...

Simple easy to use plan and everything now covered... I was recommended to run 50% but I may bump it next time to 75 on the Base..

So here is why i chose CES. For one I am currently running sterile and the complete line is. Two the information from them if it works as told is pretty interesting. Separate cal and mag as they need different amounts at different stages... makes sense... They have a recommended PH plan different from flower to veg and they recommend after base nutes you PH.. then the rest of the line drops PH to 4 which takes 24 hours to rise back to where you set it. Whether bullshit or not they claim this lets the plants take in the entire nute tree. helps to avoid deficiencies in sensitive plants that have strange nutrient habits. ok ok so sounds like it would make sense..

I added base nutes and my PH was 5.9 BAM!

no down or up needed I will just do the correction tomorrow night as scheduled. That will be a plus if it is this way into the future. only 700 ppm in veg and 800 in flower... Very low for what I usually run but in a couple weeks i'll bump the base higher... I'll see how they like this stuff..

Another reason for this line is it really is in expensive overall... I bought gallons and that adds up quick but I should be able to run off this for quite some time...

And probably most important to me was it is a complete line all from one manufacturer.. DMZ is the only outside company. I want to ensure the plant is getting everything it needs through out the grow. If I have issue's it should be from me.. not because I didn't realize my line up was missing some of the nute tree.. or needed a boost in area's. I was running 4 brands really.

I was using GH for several grows and have no issue's with their stuff.. but it does gunk stuff up and the CES I was told is some of the cleanest around and it should excel in top feed systems.

So thats about the run down. I threw a not so ready WW into flower as I have literally 5 empty slots in flower right now. well 4 now... Another couple weeks and I will have several ready.. So the question at that point is do i throw a batch in or stick with every couple to few weeks... Guess i'll figure it out when i get there....


Thanks for stopping by!

You just asked me to swing by. So I didn't just read through the 22 page journal her but "scanned" this last page. Do you realize you have some serious nitrogen toxicity going on?

On your 1/12 post pics 1, 2, and 3 show plants with detrimental Nitrogen overdosing. You have the first 3 major sings there clear as a bell and the 4th sign which is really the point where things get real bad is starting.


Again I am just scanning this for the first time and not reading a heck of a lot but are you clear about this? Because at the top of the page you can see it was real bad in December and it is even worse now.

Bam ! I had guessed it was nitrogen but was not sure...My other guess was drowning.. not enough air. That started early in flower and that plant never really took off even though it had a pretty big root structure. Thank you for looking at it and that wasn't even the reason I had you come to my thread. I just figured you would stop by a few weeks from now to check on what I thought of the new nutes...

Ok so idea's on what causes it.. PH was good .. PPM's never over 1k and I used Lucas method and very light on the nutes in flower. Mostly supps in flower.. Same plan I have used for multiple Grows only changing it now. But I was never running Kool Bloom in my last ones. I have made it to harvest in all my grows but I have only made it there without any issues on one PC so far and that wasnt perfect but no real issue's. That was really the reason for the nute switch to get a better plan and start to get smooth runs. I don't need the plant to produce incredible yields. I want it to be superb on the quality side. But of course that goes hand in hand.

OH NO OG i was not asking you to catch up on my blog... I just was hoping you would just stop by once in awhile to check it out. 30 seconds and you nailed an issue so ... I hope you actually stop by more than that ..lol
I tell you thanks alot but really it is not just from me... I see you all over now helping out and as i mentioned on the other post. The effort you give and knowledge are superb and it deserves mentioning on a regular basis ...

Thanks

FE

oh that plant got chopped... worst plant I have done yet... Directly next to it was a DCC that didnt have as bad of an issue. really almost none until i looked and it had a few nanners ;/ probably a diff thing all together on that.

So I will continue to learn and really i am at month 7 in my knowlege at this. I need to remind myself of this.
 
One of the other signs of the toxicity of nitrogen getting to overload is slowed growth. When she stopped growing fast you had crossed the line already. This is a great example about fertilizers in general. Nutes are not food. they are used as a helper in converting the results of photosynthesis to useful plant stuff. Giving a ton of nutes doesn't help. the amount of nutes a plant needs is based on how much photosynthesis is going on. So more lights and more fan leaves means more nutes. (so get ready to have your mind blown)... This is why the nute profile changes through out the grow. If you are getting more and more fan leaves then you have more photosynthesis. so throughout veg more of this is going on each day. so in order to prevent deficiency we need to up the nutes as we get more and more fan leaves. and then at some point in bloom we start to see the fan leavs stop coming out and stop growing so the photosynthesis has peaked and the nutes have to stop. then the fan leaves start failing and the plant starts to take nutes back from the fan leaves so not only are they not doing photosynthesis but the nutes in them are being reused so we need to drop the nuets WAY down fast.

You can look at the power of your lights and the number of fan leaves to know what you PPM should be.

Look at the chart below. Look how fast it drops of the EC (PPM) in bloom when the plant stops growing and is focused on bloom production.

CCH2O-Recommendations-Graph-1024x743.jpg
 
Current Cultures web site. They make the premiere best hydro platform out there for cannabis. It is a hydro system too big to be used on anything but cannabis. It is very expensive and may people try to make knock offs. On their website they have this chart posting what they have found is the ideal way to run their system. Most of it is identical for any grow even soil. All of it can be taken relative. Like the EC line is fairly accurate but if you have lower photosynthesis happening then obviously that has to drop. I have a guy in a journal running a simple tote DWC and his EC is nearly dead on that running a 600 W. And he is not following a program I taught him how to read the res and let the plant tell you what to do.
 
Let me start with:adore::adore::adore::adore::adore::adore:

Ok so now that that is over... I saw you posted that on CC420's page thank you very kindly i am studying it.. I knew about the intake of the nutes in relation to PH etc but still new at that stuff... Part of my issue with the BK i ran was sort of the busy season along with the DCC doing well I just kinda let it go some and then yes far too late to help...
Great info as well about the nutes in relation to fan leaves etc.. I had posted a little back on my thread how I have never defoled in flower and liked the results but I always took a fair amount. Well I am a believer in the fact the fans do all the work. The photosynthesis of course is the life of the plant but it makes sense that it determines the amount of things it can intake as based on the relation to everything (ph , temp ,, etc). Phew... i'll get it someday.. lol j/k i think i am close...

I do sort of follow that but I was for the wrong reason. I knew as the plant would get big and bushy it was healthy and I would increase the nutes etc. Usually in flower it would be rolling and just continue but on the flower path. It was coincidental that following as you say in my case my plants would be getting incredible photosynthesis at that point and producing. They could handle what was given to them.. All makes sense..

Thanks OG For all the light info you sent me all the help here and damn all you do around the community. Shiggity and RSoiler I do love you two as well.. Thank you for coming by and checking things out. Please go save others all of you and I will message (keep those IM's open ) you guys sometime in the future when I am in dire straights again!

I didnt figure out the BK correctly but changed every part of my grow in the last week as I am solely topfeed now and all new brand nutes etc that will cause a learning curve but I already understand it better now. Hopefully I will do far better now. Not that most of my harvests have been bad. Just want it dead on.

Thanks all!

:peace:

I think things are good?

So I am getting use to the top feed setup and so far I love it but it definitely is a learning curve. Plus now that I have switched to CES it is also a wrinkle in the mix. Might as well get it all swapped at once but that means alot of knowledge to be gained.

I was still learning all of this so might as well learn it all right to begin with.

Let's start with the harvest on the DCC and the BK

to summarize Piss Poor...

First is the BK 26.5 G

IMGP10941.JPG


Then the DCC 80.5
IMGP10922.JPG


IMGP10931.JPG


The nitrogen toxicity fucked this one.(thank you OG for clarifying it) Probably the switch to the new flower room.. Variance in the temperatures... the switch at week 5 from LED to HPS..i can keep going...well let's just day I found a few nanners.

Oh well chock that one up to more learning. Or more silly stupid idea's in mid flower... But oh well more for projects and there really wasn't too many seeds etc. Now things are all switched over to the drip everywhere. Temps are all in regulated state etc. Things should be good from here.

Once i get it all figured out...

Any plant that had roots in DWC... well all of them.. had to get use to drip... I kid you not it is like they all made all new root masses. Plants like the PC the root became almost like an extension of the stock. Thick thick. Spreads out as it goes into the 1 gallon pool in the bottom.
Look


IMGP11012.JPG
IMGP11002.JPG



Second pic there on the left is the ACDC. It popped all new roots... Doing finally very well for a fragile little thing... The old roots hated the soil to drip conversion and almost died.. lost 8-10 lower leaves.. Until the roots started getting bigger it was eating itself. Now this last few days it is doing well... All the plants especially now are popping nicely. Almost all of them had zero issues with the conversion from DWC to drip but they all did stunt. Now that I am seeing all the drip created new roots things are back to better growth.

IMGP10992.JPG


SD and HG seeds are growing very well! Everything is..
There is a BK flower back to veg clone ugly as shit in there...
PC,DCC,ummm... WW TW and the ACDC i think...

So if i had them on drip to begin with I think they all would be further along but as long as the worst of it is past me great....

So in flower let's see how that looks over there...

IMGP11022.JPG
IMGP11032.JPG
IMGP11042.JPG
IMGP11052.JPG


Poop! and another Poop next to it....

So here is the deal.. the TW in there for one was clone that went to flower early... had a nitrogen issue so it missed stretch or just cause it was a clone didnt stretch at all... But......... it is producing closer to normal for what it is at this point... I got all out of cycle with the new flower room and all so I threw stuff in to keep things going but i now see it was sorta silly.

The things is like with the WW that is small I threw into flower... It really is no difference in cost between 1 and say 3-4 in flower for me on top feed. I wont use up the nutes in the res before i change it so running 1 plant when I can run 3-4 is silly. So there will be some serious plants going into flower but I dont want to run it full then empty so I will keep throwing them in 1-2 at a time for awhile... More based too on bigger from veg to flower...
The next batches will be more like what I expect... and hopefully i will have a new LED to run as well.


So lets talk nutes...

The CES stuff adds foam... Not a lot but upon inspection it is little tiny buble that disappear on touch.. Can't be a bad thing as seems like it's air related... So the plan is add your base and PH to 5.8 or so... Then when you add the plant amp i think it is it drops the PH to 4.2-4.3 for a day or two. Not sure why but my 10 gal took 24 hours and my 15 gallon in flower was 48. They both ended up at 6.1. I have bumped them down a little and seem to be struggling a little to keep it down but it may be I am working with more volume. I use to adjust 5 gallon pails so it sounds as simple as doubling or triple but no... isnt.

So I have them stabilized a little better So I'll see what it does from here. Bigger res should be more stable once set.

So let's talk about the idea of letting the PH drop very low for a day or so. If you look at the nute availability charts you see that the intake varies on the elements. So by theory the drop will let it take in a specified nute at certain PH's for a couple days to boost up certain things with max intake along the way with the ph rising then it reaches a point that is more wide spectrum and broad. Sounds BRILLIANT! ok just sounds it proofs in the pounds. ;)

This theory in my research was one of the reasons I wanted to give them a run..


So that is the latest sitch in my grow. Stay tuned to see this new setup and my testing .. playing with it...
When I get the new lights I will definitely be doing side by sides... Should be so easy.. Top Feed they will be both drinking the same tea ;)

Be safe 420 family... Thanks for coming to my place for the time you did ..lol

Everyone I know uses pH at times to isolate nute uptake. That aint theory that is common practice. Usually it is for calcium Def. And you are letting it go up to 6.4 or even higher but then you gotta dump and start over.

I don't know if I ever pointed you at closet cases journal but if you look for it or want me to show you I explain in there a lot of stuff about how to get a stable res that you can walk away from. Also how the best way to manage pH is via PPM not adding UP and DOWN.

I can retype it all here if you want but I am doing 12 hour days at work right now and I am very tired. It would have to wait for the weekend for me to explain DWC res stability and pH cycling (that's what its called by the way...your "theory").

ah heck just in case...
ClosetCase420's - RDWC - 600W MH/HPS - Wonder Woman - Grow Journal - 2015

But a good grower understands the difference between Veg which preferably runs closer to 6.2 and bloom which runs closer to 5.8-5.6 for exactly those reasons.

Below is an enviro chart from the premier best Hydro product on the market. this is how they say to run the system. They know what they are talking about. Look at the optimal pH throughout the grow. And do some research outside here. You will find Lettuce grows best at 6.2...coincidence? I think not. It has nothing to do with the plant. It is about mobility of the nute in solution.

Ok so first off I am not sure why I mentioned OG as the one who helped with the Nitrogen def. Although OG has helped me alot in this case it was you VI .. hate that i gave miscredit. Sorry...

I read almost the whole thing.. absolutely you do not need to retype it.. Thank you for typing it all there as that was a lot of work you put into his grow.

CES is what is causing the PH to fluctuate a little well more specifically the Plant Amp is what i was told causes it. So i know silica works as ph up as well as it usually has potash as you mentioned... But when I tried it I seem to notice little change in the PH but I was concerned to add too much PPM. The PH was really stabil before I did the recent changes to CES nutes so I believe it is just a new learning thing. When i had GH stuff res would sit at the PH I set very nicely.
And it isn't really fluctuating much if at all but i may not be bringing it down enough to stay once it is diluted.

I am going to reread the PPM to PH part as I am still a little confused but it does fall in line with adding the Silica etc.. but no need to retype it.. just need to find some extra time is all.. I get back over to his cc's thread again.

That chart is awesome thank you... When you shared it the other day it was the first time i had seen it.. And i have looked at alot of charts. that one is really good!

Thank you for checking in again VI I know you spend an incredible amount of time helping people get there stuff going. I for one appreciate it and you stopping by to look at my stuff as I work through my noobism and new setup..

I feel I am very close and when i get top feed all figured out I think I will be successful for a long time using it.. Love the system and the concept.
Thanks again for the time

One "secret" to the pH thing (nothing is secret just many people don't do research), is if the pH is dropping while the water is dropping and the nutes are stable that means you need to add nutes in a healthy system. That seems backwards but here is why.

#1 more than 99% of the water absorbed is used for transportation and then transpiration. Almost none of it is used in the plant for actual growth. The roots siting in solution will absorb the nutes and build up a concentration in the roots directly proportional to the concentration of the solution. They can't absorb more than basically what is in there and if there is more than they need that is where they will get too...that is why we can burn them. Savvy? What I am saying is the plant does not decide how much nutes to absorb. The res concentration decides that and the roots will stabilize their concentration in line with the concentration in the res. The water is then used to push it up the plant where it is used and the concentration in that water again is not requested or maintained by the plant. It is whatever we force it to be.

(FYI if you understand how Mycos works it helps greatly to alleviate this problem)

So I said ratio because it isn't exactly the same and in fact the roots store up nutes and they are sitting there waiting for the plant to transport nutes via water by transpiration in the leaves to bring it up. If the nutes in the roots are more concentrated than the res then they will start to leach back into the res. And that is when the pH starts dropping and the res concentration is not changing. The plant can't absorb more and it keeps sucking up water but the PPM is stable.

Now normally that is what you want to see but also normally the pH is stable. This is only an issue if the pH is tanking on you and you have a good clean system like you are full of beneficial bacteria. (sterile is not a clean system it is a dirty system that is mostly clean...running beneficial bacteria makes a clean system).

So just understand I for example don't need to add no pH UP or DOWN to the res during the main part of a res. I dump about once a month on principal unless I have a problem and at bloom switch over. I will go many weeks just topping off with more solution. I have a buddy who never dumps his res. You don't need to dump the res. You need to maintain a healthy res.

Gotta run but that is one part of it.
 
One "secret" to the pH thing (nothing is secret just many people don't do research), is if the pH is dropping while the water is dropping and the nutes are stable that means you need to add nutes in a healthy system. That seems backwards but here is why.

#1 more than 99% of the water absorbed is used for transportation and then transpiration. Almost none of it is used in the plant for actual growth. The roots siting in solution will absorb the nutes and build up a concentration in the roots directly proportional to the concentration of the solution. They can't absorb more than basically what is in there and if there is more than they need that is where they will get too...that is why we can burn them. Savvy? What I am saying is the plant does not decide how much nutes to absorb. The res concentration decides that and the roots will stabilize their concentration in line with the concentration in the res. The water is then used to push it up the plant where it is used and the concentration in that water again is not requested or maintained by the plant. It is whatever we force it to be.

Ok so first off sounds repetitive but thanks VI. For what ever reason I totally got this. The explanation was really good on this. I am going to give it a shot. PH water to use to drop it and silica to raise it. I use to dilute the res sometimes with PH water in the past but to adjust PPM. But I understand this will be using the PPM to manipulate the PH.

I love the idea of it because I add more PPM currently with PH down each time i try to drop it. This would be easier on the PPM's rising.

So thank you for this great info!
