Perlite for passive hydro marijuana system?


#1

Is it feasible to use perlite alone in a passive hydroponic marijuana growing system?

 

Perlite does not have capillary action, meaning it won’t draw water up from the reservoir and can’t be used on its own. It works fine as a component of planting mix that has peat moss, coir or compost, lava rock, or horticultural clay pebbles.

It wont work. perlite will float away. It is basically Styrofoam.
