Well, this is just an experiment to see if I could do it. This is my hydro laboratory. Once I get my beans going I will give them a 2-3 gallon container each. I needed to know if I could clone without rooting hormone (yes), how long the clone would take to root (9 days), if I needed to trim larger bottom leaves (no), could I grow without medium (well I still needed some place to keep the beneficial bacteria) (yes), could I grow using a pump and no bubbler (yes) there's enough water circulation, could I use tap water only (yes). Would I get algae if I had beneficial bacteria (not yet), does light destroy roots (no), however drying out roots is a sure death. Could the seedlings survive submerged underwater (no), can I grow onions (remains to be seen), will lettuce do well (yes), can I grow in dirt and transfer to hydro (yes) plus some others I
can't think of right now.

Yeskaa, how do you get your plants to stay erect (keep it clean) without medium?
