Exactly. The only thing that is a problem for me is starting all the girls at the same time since I always have some new strain geting put in the mix like these 2 little BB and BBxTW I have going, LOL. A good friend dropped them on me.
You see my nute formula changes up half way threw flower so it wouldn't work rright now to have them all getting the same water, but in a couple months that should be different. Another thing, since a small of run off is necessary I do this, I use 3 gallon pots with a bunch of holes drilled in the bottom and keep that pot on a 2 gallon bucket and the run off go's right into the bucket and I just change the run off water once a week approx. Having the run off is also nice because you don't get any salt build ups in the medium.
