100 percent perlite!!!??why do you choose to exclude the dirt which, judging by whats under every single plant outside, is ver conducive to growing a plant?
ive done dirt for years and here's the problems that arise...
1. Bugs (gnats, spidermites, aphids, etc...)
2. Ph +/-
3. Compacted ( even when ammended with perlite)
With perlite its reusable... as soon as u get done with one u can repot in another. no ph fluctations and less stress for the roots to grow.
dries quicker.. its basically a passive hydro setup
My first time using it i pulled 3oz using a 2 ltr bottle... i usually start seeds in soil ( 1/2 cup) then transplant from there... with clones they go straigt from cloner to the hempy... try it out.. bet u wont go back to soil.
