Munki's Ebb n Flow 3 x 3 SCROG 400W HPS Grow

If you catch them when they have just started to poke through that shouldn't be as much of an issue. You might notice that some buds exist on both sides of the screen by harvest time though. Then you can pull them the rest of the way through or snip at the screen and have two pieces. I'd recommend the later as it won't disturb the nice coat of trichomes that you should have.

BtW - Nurseries sell a tar-like (might even BE tar, IDK) substance for patching wounds on trees. I would guess that a little dab everywhere that you've cut off growth will seal it against future growth. This is speculation, however, as I've not tried it.

My first ScrOG, so my strategy was to let the ends grow through for 2 - 3 days to get some stretch, then pull them under. The buds that the tip along with sites down farther on the stems now typically will be right up against the screen. The hope is to have those bud sites to each grow upwards from the now horizontal branch like LST tie-downs do. Bigger holes in the screen would make this easier but I'm done with that I think. I have plenty of vertical height to use so there is no chance the tips will reach the lamp. That I can guarantee with this grow.

The underneath growth is occurring because there is still some light underneath and those internode spots are still have the ability to grow after being pruned. Other ScrOG setups have the screen completely separating the upper and lower parts of the room so the underside kind of gets sealed up. That doesn't happen with this grow so the necessity of growth clearance underneath isn't as paramount. Just mainly to not have the plants divert too much energy to these lower budsites.
 
those top colas sure look like they are filling out with some nice white hairs. do you have a harvest amount that you are striving for munki?

those small bud sites look fun to smoke to test out the potency, tiny snap bowls(;

keep up the great work, we are all rooting for you:cheertwo:

Yeah, but I wish I had more space, money, and time to build out more rooms so I can learn even more.

that exactly what we all want! i am waiting to buy my own house in a year or two when i finish up my research and grad school. when I do, i think I will be building a few 7' diameter wheels in my basement. lol. the light distribution is just too sweet to ignore. either this or vertical. I was so close to buying a coliseum instead of my volks. i'm all about light distribution. mainly because efficiency is measured per watt, and if nothing else, i want to be efficient!
 
God some bad weather for the next few days at least. Upper 80s with low 30s% RH. My tent is over 90 inside and I saw a max of 94. Not too happy dealing with this for much longer.

Got a portable A/C. I just may have to rig it up somehow to run during the day and direct that cool air into the tent. I would have to stop the forced intake fan and outtake air that is on the filter. Hmmm, is it worth the risk messing up something while installing the unit? I'll have to think about it.

do you have your schedule on during the day and off at night?

No, heat is always a concern in late summer here so I run 8PM to 8AM. Not good to have hot "nights" though especially in flowering I think.
 
These were taken last night soon after the lamp came on.

These last 4 pics show the 4 quadrants of the screen starting with the back left and ending with the bottom right as seen from our vantage point outside the tent.

Munki, I've been quietly watching this for awhile and must say it has made a convincing argument for the SCRoG method.

Tried to rep you, but I gotta spread it.

I'm happy I could help extol its virtues. It isn't for everyone, but it is an excellent solution for many smaller grow spaces and lower intensity lighting for sure.
 
Thanks everyone. From here on out, I will be "watching the grass grow!" I'll get pics every 2 - 3 days and try to capture anything that catches my eye along the way.

A side note that excited me was in my reservoir management. I'm using 5 products currently in my mix. My last rez change a week ago was only filled to 10 gallons. I do plain RO water addbacks to maintain the fluid level and take daily pH and TDS measurements at the same time each day. Using information from this, I deduced that I had a drop of 23% in overall nutrient concentration levels. I was able to use the formula of (TDSstart - TDSnow) / TDSstart to discover this. I then calculated out how much of each nutrient I needed to add to return the rez to its original levels along with full dose levels for an additional 2 gallons I wanted to add to bring the total volume to 12 gallons. After doing all this and mixing it up, I was only off from my projected TDS value by only about 40 PPM! :cheertwo: Considering I actually used a measurement of TDSnow from the prior day, that day's nutrient use would easily explain the amount of discrepancy I saw.

I'm thrilled as I want to minimize the amount of full reservoir changes and my plan is to not empty the rez until harvest. On my next planned grow, I will run only one reservoir fill the whole grow with only water and calculated nutrient addbacks. I will also only employ the Lucas Formula for GH Flora series using only 8mL/gal of Micro and 16mL/gal of bloom. I plan to crack the one DinaFem Roadrunner Autoflower and put it in the same grow bucket I use now except it will get all the space for itself. Run the lights 20 on 4 off the entire grow. I thought it was a great one to run indoors during late fall or winter season.
 
looking good munki.


its all money from here on out. cant wait to see these guys fill out and girth up.

you obviously know you cant scrog the roadrunner right?

I think i'm confused. Are you planning to flush during your grows? you know prior to nute regimine changes or so salts dont build up.
 
with ebb and flow, if you dont want to change the res, and still want to flush, all you need to do is pull the return line out and drain into a bucket and top flush the medium 200-300% of its volume. easy, and can save the nutes if thats what your trying to do.

one word. . . although anything is possible, and i've gone a whole grow with out changing my res before. there are always stuff in your nutes your plants wont want. and if you dont change your res they will build up. then when you have 500 ppm, is it mostly phosphorus, or mostly potassium, how much calcium is left and how much did the plant uptake?. I will never go a whole grow without changing the res cause i need to know what I am adding to, and the best way is to start from 0. I just don't think im good enough at reading my plants to see exactly what they are deficient in and add more. esp since i change strains regularly. that being said, if you use beneficial microbes and enzymes, you can break a lot of that down and make it available to the plant again. so that will help.

i would still flush the bucket though.
 
Bad Munki
please do not this. I am sure your math is on point. This is the problem is this...you have no idea what nutes your plants are leaving in the resovoir. your trace elements will be all out of wack causing a guarenteed lockout and loss or death ocurring. been there and there have done that and have the t-shirt. I did not listen to friends here and I crashed hard. do u think I want to move a 200 gallons of water a week? just draining the res isnt enuf. you must flush as well.
 
Those budsites are gonna plump up mega in the next 6 weeks. Do you think the 400 is too much for the 2 plants? In the future how many plants will you put under the screen?
 
I do realize that the plants will take up the nutrients unevenly and that I will eventually will have the rez out of whack. I will monitor for variations in how the pH fluctuates day to day. If I start having trouble controlling my pH, I will use that as a sign along with carefully looking for plant stress.

I did not come up with this idea out of the blue. I'm going off of what some fairly famous people in our circles, "pH" and "Lucas" have discovered over many years of work. There is a huge thread that Lucas did on another forum where he did Q & A with everyone there. Also, pH put up a website called CannaStats that kind of summates his work. He is often the one credited with creating the ScrOG method.

I don't want to step on anyone's toes so please do not think I am ignoring your advice. I just may need to get some of my own lumps of hard learned wisdom along the way and this may be it.
