PPM TEST DAY 4

Okay, so today is the last run of tests I will be doing. This will conclude my previous assumptions of the Bubb NEEDING an excess of 1000 PPM of nutrients.

Excerpt from notes:

PPM TEST DAY 4

-1st reading: PPM-773; pH-6.8
-2nd reading: PPM-773; pH-6.8
-3rd reading: PPM-775;pH-6.8

To conclude, I started 4 days ago with a PPM of 849, and now have ended up with a PM of 775. I will aim to get the PPM to a final high point of 950. I will preform similar tests in the background in the future, just to ensure that 950 is an appropriate range!

I will be out for the next 4 days. In the meantime I will be disconnecting the recirculation feature, and will be cycling the feed for the next 4 days directly to waste. This will keep the pH of my res stable at 5.8, although I won't be able to control the pH in my medium. However, 4 days with the appropriate pH of nutrients 'going in' should be able to hold the Bubb off until I come back.

Until then, Happy Thanksgiving to all. And stay safe :Namaste:
 
Happy Thanksgiving
 
Happy Thanksgiving 420.

I purposely left this question alone :rofl: But now I can say, "of course I do man;)" I found 4 gallons out of 12.5 gallons left when I returned.

FLOWER DAY 32

Hey everyone of the 420 community! I hope all of you had great festivities these past three days! I surely did;)

So we are just about about halfway there guys. The Bubb and the bagseed were just fine for the time I was away. For the first time, I completely forgot about my operation while I was gone. The underlying thought of something going wrong, completely removed. I guess that's what food lethargy can do to you!

I left 12.5 gallons of nutrient feed at a PPM of 950 and a pH of 5.2. This was on a 1 minute timer, 3 times a day, and all circulated to a waste bucket.

On my return I found 4 gallons left in my res, at a PPM of 890 and a pH of 6.2. So in 72 hours there was a change of about 60 PPM (insignificant change) and a rise in pH by a whole digit.

The Bubb is really starting to fill in. Although by the rate of which she is developing, I am looking at a harvest day at around 70 instead of 60. SORRY FOR THE UPSIDE DOWN PICS

Upon my return, the bagseed did not show any further development of male pollen sacs. I will be continuosly monitoring it daily for any other signs. Nonetheless, it is still EXTREMELY resinous.

Okay so I stopped by a local hydro store in the area in which I visited for the holidays. Boy, did they have a selection of goodies.I found myself talking to these guys for an hour hour, bouncing around the subject of beneficials and grow setup, etc, all disregarding the fact that we are talking about cannabis here. It was weird talking to a person in real life about the intricacies of my grow, as the only people I've disclosed this to are you lucky folks of the 420 community!

Anyway I got my hands on GH CaliMag, a pure synthetic supplement, and I also topped up my supply of FloraBlend.

While discussing the subject of beneficials, the sales rep gave me some FREE samples of a Cali-based brand, Primordial Solutions. It is a highly concentrated myco's with endo's, and an NPK value. I told him about my brewing method and he uses this stuff in conjunction with great white to add to the diversity of microbes. I'm going to try it out at 1 drop per gallon come my next grow, for a side-by-side comparison with a plant that gets fed the regular tea. But I'm happy to get FREE stuff :high-five:

Okay, I had a quick question to those with experience with plant diseases and fungi. I came back to find some of my lower leaves showing signs of spotting. It was normal for some lower foliage to start yellowing out and die off, but now some leaves in particular look like the where from a nutrient splash, but almost a brown-moldy color starting to form. I'm sure it is not PM, since my environment is just to dry and cold to support open air fungus.

In any case, I was reading the forums about blight, and the formation of it. I highly doubt it could be as severe as I am thinking, but I would like to get another experienced opinion on the matter as well. :Namaste:
 
wow, they are fucking gorgeous. maybe a tad hungry those leaves so they were weakened. I don't think that mold a concern, there is mold naturally everywhere, that's a tiny overgrowth :high-five:

I got that same mold on my cymbals where my sweat drips and it tarnishes -_-

I hate those marks
 
Nice update and glad you had some serenity from the madness of extreme growing. Some more research suggest to me that maybe the CaMg is not causing ph fluctuations and it seems you have a fairly stable res at 10 tenths increase in 4 days. Did you use CaMg in that res or CALiMAGic? I am now wondering if the plastics used to mold my res container may be a culprit, or possibly wood cabinet, paint I used etc etc.

Hope the brown marks are just splash burns. Your environment looks excessively clean from what pictures show. Is your inlet air filtered? Maybe a cheap hepa(like) filter would help and prevent future outbreaks. Don't know if the tents are relatively air tight and if not, I wouldn't even bother with a filter unless there's an intake fan that draws from a single point and pressurizes everything after it which would push air out of the tent, even if minimally. Only drawback is fans make lots of noise.
 
Thanks B.Real, that really takes some pressure off my shoulders.

>>> Did you use CaMg in that res or CALiMAGic?

I used GO CaMa in my res, and only just mixed a 5 gallon container to sit over night with GH CaliMag to see any correlation. My inlet is passive, and is semi-filtered with a fine nylon screen. I remove finger-fulls of dust monthly from the screens.
 
Does the grow tents seal with magnetic strips or velcro? If the former, GTG, but if the latter, and especially if the spots turn out to be blight or other airborne particles causing issues, a filtered inlet fan mounted low inside the tent would be the most in the way of a solution I would think, but for the noise it might create, might not be a viable option for a stealth op.

It uses velcro, and flaps to keep everything lightproof. I have no problem with night cycles as they coincide with my actual night times.

I will be exchanging the use of this current 240CFM fan, from exhaust to intake, and will be purchasing an inline fan with at least 400CFM. If I include a controller in this purchase, I will have better hopes in having a better hand over my grow temps. Noise is not so much of a concern for me, so I will definitely look at my filter options once I make this purchase.
 
I just got a 400 right before losing my job for around $70 with shipping. Man is that thing loud and I won't even consider using it here. Good decision to repurpose your existing fan, but I wouldn't change the position till after you get the other as heat removal outweighs possible airborne spores IMO b/c the heat you know is real and constant.
 
>>>I found 4 gallons out of 12.5 gallons left when I returned.

Nice job. I did it once, but when I returned, I found 0 gallons and dried up plants :-( Obviously your calculations were much better than mine!

>>>will be purchasing an inline fan with at least 400CFM. If I include a controller in this purchase

FWIW, On my 4 x 15 flower closet, I use a single 6" maxfan on the lowest setting, 201CFM, and it runs 24/7 at a constant speed with no controller. Same setup on 4 x 6 veg closet. The fans are really quiet at the lowest setting. The 400CFM fan sounds like a jet engine.

Before spending the cash, I would suggest you try to PULL the air thru the hood and THEN out of the tent, instead of PUSH it. You will find it works SO much better. That said, that 6" duct boost fan doesn't have much power. The 8" duct boost fan is much better and not louder.

WRONG: (some pic I found online)

RIGHT (my veg room)
This would be even better if I mounted the fan at the ceiling and didn't make the fan push thru the 3 feet of ducting.

If you do decide to get a fan, that 6" maxfan is expensive ($139 on ebay) but it is awesome. It will last forever and it has 3 speeds so you can grow with it as your needs change.
 
I just noticed everything on the site that I usually order from has been marked up, probably b/c of the holidays. Plus the fan I got does not have adjustable settings which means I need a control module. And now based upon what Capn has written, it would be better to get something like his suggestion.

I wonder why the tents use velcro over magnetic strips? Magnetic strips would give an air tight and light tight seal, velcro, not so much.
 
As for the velcro over the magnetic strips, the only explanation I can come up with is the 'shear' strength of velcro is much greater than a less friction-producing surface as a magnetic strip.

I probably am going to test out my 6" boost fan in the order Capn suggested, and see if that makes a significant difference in temperature. If so, I will only be purchasing the 8" boost fan to replace the existing 6" fan. No need for expensive fans if these ones can do the job ;)

I got 2 fans from a yard sale couple years ago for $10 for both. I use one on ground for my room as cool intake the other is further in the room for minor oscillation and they push the hot air up and out of the room steadily. Found my sweet spot thanks to simple fans haha :thumb: The other fan on the floor actually blows air against the wall seems to encourage the hot air to go away so long the door is open a few inches. Yer hydro setup would work in my room real well cus there is no way the reservoirs would get too cold even the bare floor is warm :) <3 yer set up man can not wait to try a cut and paste of your setup one day!
 
I have to buy a speed controller as the exhaust fan I bought for my tent is way to powerful, and with the noise level there is no way my GF will let me add another fan :laughtwo: So, I'll have to slow this one down and hope it allows my vents to work as passive. As it is now you can see all the walls pulling inward when it's all closed up.
 
Hey Sweet Leef, how many CFM is your current fan. I can tell you that even my low 240CFM duct fan makes quite a bit of noise (equivalent to a bathroom exhaust fan) while also pulling the walls of my tent inwards.
 
it's a 6" 435CFM fan. I got that one because I will eventually be cooling a 1000W HID. Still running full boar, it's a louder than a bathroom fan at the mo. I am also trying to find time to build a box out of MDF that will eat up some of the sound for sure. It'll also eat up some head room...
