Yeah... Kinda on both those posts...
I find that the best you can do is determined by the light... The bushier the plant, the smaller the buds... And having like 100 buds that weigh a pound vs 20 buds that weigh a pound saves a lot of time in trimming...
I average a pound per light, sometimes more, sometimes less...
Having an even canopy will get you the best results regardless, being able to use the full power of the light and all...
And as far as the 5gal pots, the more root area the better, more surface area for nutrient uptake...
And master- do you use potassium silicate, or silica?
It raises the pH, so, adjustment is necessary, and you have to add it first, before any of the nutes...
It improves nutrient uptake acting as a catalyst, and also creates stronger cellular structure... IE... Thicker stronger stems...
But, even with that, in the last two weeks or so of flower, I still have to tie up my buds... I think it works better than staking.
I use mason line tied to the chain that suspends the hoods, looped around the colas and pulling them up towards the light...
Looks like a "puppet master" for buds after I'm through.
