I use hydroton. I start them in Rapid Rooters. No problems for me.

Beware coco coir is going to require frequent flushings with clearex to prevent salt buildup. coco is notorious for salt build up.

Good Luck
VillainVida Reviewed by VillainVida on . First Time Growing So I just recently moved from Southern California to Florida, I am still a patient there and really don't wanna be prosecuted for "buying drugs" so I have decided that growing is best I have never grown here or in cali and would really appreciate it I'm using a closet roughly 6'x2'x8' Ive been looking at hydro systems (basically homemade Resale) like this Hydro2Grow 6 Plant Hydroponic system 10GAL LETS GROW! | eBay and probably will start with 4 seedlings just to get the feel for it.
