In my opinion you can never supercrop to much, in fact I do it every 4 days all the way up until 2 weeks into flower, think of it like this. If I gave u a scale, a pencil and a flat peice off wood and asked you using either the pencil or the flat peice of wood and your body weight which do you think you can apply pressure and get more weight from??... A tall pencil where all the weight is distributed down the center or the flat wood you can stand on and apply your full body weighed evenly all over the wood. It's called barring surface par.
The same goes for your plant, an like I said I supercrop 2weeks into flower. I start supercropping the first week after my clones take root and supercrop every 4 days and after every node growth, this makes your plant distribute the growth energy evenly and completely eliminates all the subsided energy you would get if you were to jus grow your striaght up.
This dramatically increases your yeild! I myself average 10oz a plant indoor. And I only use 2000w for each one of my tables.
also a few other things...
if you wanna or are gonna try this I reccommend fimming or topping your plant before you start the supercropping, lollipop the first day of flower, and on day 7 and day 14 of flower hit your plants with some dutch master reserve, which is concentrated cannabis female hormones, this helps with the stress of supercropping and stops the hermi of your plant if it was thinking of doing so. I have yet in 7 years to have a hermi. hope this helped!!
Happy gardening!! Best of luck to all!!
