I use ~2-3 golf ball size lava rock in the bottom ~ 3/4 of the grow pot (Air Pot/6" net pot) and cap with river/ornamental rock. The smaller RR blocks light penetration + helps stabilize the plant when young. See my 21st Century Drip/Spray thread for detailshey flora have you ever tried using lava rocks as a medium? i hear they have there own nutrients that plants like but not sure
