While waiting on mothers to clone I did grow 6 in a container 2 were males and I took out as much root as posible from the males. With no problems.

Yes dead roots in your res are very bad but not the end of the world. Look up my thread locnar1958 How's my girl's. About 10 days into flower Zandor had me cut roots on one of six back to just the water line. I got all the cut roots I could out but had no ill effect of rot.

If you have the room, yes buckets I think would be best but in a small space we have to make dew.

I hear ebb and flow peeps talking about how hard it is to keep clean cause roots tangle and you can't just pull them out to clean algea.

Most all of mine have been fem or clones so no worries most of the time.

I don't mean to slame anyone it just happens alot of peeps have more than one per container.
