Yea I use coco in solo cups too never get anything nearly as large and bushy as that lol. At most they will get to about 9 inches but stay thin and lanky. I dont get any real branching until I transplant.
How long do you leave them in the cups for? I must be doing sonething wrong lol.
I flower in solo cups
pure coco,, no pearlite
watered/fed daily,, except when seedlings..
All coco is not created equally,, I use baled coco,, and some I rinse twice before using..
I layer the 3 grades of coco I use..
Coarse on the bottom,, a medium grade in the middle,, and loose finer grade in the top layer..
No I don't veg my plants.. They are 1' to 2 1/2' tall at finish.. Depending on the strain and the time to flower..
Neville's Haze was a big plant after 130+ days.. A plant like this is so rootbound it had to be watered/fed 3 times a day or be dry..
Hope I helped,,
