First SCROG failed to impress - how to improve?

[philbu]

I have one grow under the belt. It was successful, but failed to impress. Indoor, SCROG, 4x6 area, veg with T5’s, flower with 2 1000w HPS. Battled modest spider mite invasion and won. Nipped powdery mildew in the bud. No obvious nute lockout, nor burning. Humidity well controlled, got the harvest time correct, dry/cure, no problem. Grow looked good overall. However, due to one, or a combination of factors, the total dry yield was 18 oz. Too many plants for the area (18) or pots too small (3gal), or a few extra- warm days in the room, some light loss in a 4x6 area in a 10x10 room, maybe could have pushed nutes more, I don’t know.

I will have a better handle on those issues, determined to do much better this time. Two goals: First, 10 oz per plant. Down the line, 1 lb per plant.
Focusing on the first, is 10 oz per plant in a scrog just a myth or ugly rumor?
If it is possible, how to achieve this goal in the same 4x6 space with the same lights?
Maybe 6 plants in 5 or 7 gal pots? 10 gal pots?
Scrog or LST tie-down style?

I’m going with Green Crack again, it’s Sativa leaning, known to be a good yielder (user error on my part) and fast flowering (true).
I grow mostly for others and would greatly appreciate some advice from experienced growers who get good yields.

Thanks much!

you should be able to get 1gpw easily with scrog. here are some tips. ive had 10oz+ from a 250 plenty of times before.

use BIG pots. as big as you can fit really. pot size is proportional to final plant size and yield in soil.
let the colas get some height above the screen. with 1K watts you have a useful penetration of about 2ft, so you can let the plants get up to this height off the screen. think of a scrog as a 'box' full of colas rather than a flat screen of buds.
try to avoid gaps in the canopy as much as possible. gaps are wasted yield.
you could also increase your canopy size to 4 x 8 and still get more than enough light intensity with 2 x 1k lights.

I know, I know! It's a rule of thumb, that's why yield was disappointing. Even 2 lbs final weight would have been encouraging...

use BIG pots. as big as you can fit really. pot size is proportional to final plant size and yield in soil.

So, that's a factor I'm trying to figure out. Six pots, 5, 7 or 10 gal would all fit in the space. Two things about that,(1) time necessary to veg plants to take full advantage of pot size and (2) would plants get too big for the 4x6 space (height is not an issue).

Sure, letting colas get 2 ft above screen sounds great, just have to get that to happen, ha. : )

I can avoid gaps, had good coverage last run, pic below. Unfortunately, can't quite manage a 4x8 area in my 10x10 room.

Thanks, VG!
