I have only one plant in my DWC now, but if I tried to move my plant out of its resevoir lid-hole at this point, some of the roots nearest the net pot would be damaged by being compressed against the edges of the hole as I pulled it out. So be wary of that - but if you're moving them at 6", it is less likely to be a problem (fewer roots).

To prevent the roots of one plant from becoming entangled with the other plants' roots, just check on them daily, and, with fingers dampened with rez solution, gently tease apart any tangles.

I don't know if this would work, but if you have trouble this time, maybe you could rig a separator... 2 large sheets of plastic, each cut most of the way down the middle and fit together to form an X, and then drill a bazillion little holes in them to allow for rez flow. You'd need an airstone for each plant though, and roots could potentially grow into/thru the drilled holes...

Ah well. Just check 'em every day. *grin*
mackSwell Reviewed by mackSwell on . 4 Gal Veg/Cloner DWC Tub Aight here are my plans. I got a 15L (4 Gal) Sterilite tub that I want to convert into an all in one Cloner/Veging DWC Tub. I plan to Veg 4 clones in this tub until they are no more than 6 inches tall. Considering the small stature of the plant will the roots get big enough to get all tangled up in that time? The tub is about 18in(L)x12in(W)x7.5in(H). I have one 12in airstone on a 20gal topfin pump providing Oxygen. I hope thats enough. What do ya guys think? Rating: 5
