My Hanna meter is being replaced (under warranty). I should have it back next week.. I am running about 1200ppm... (with the same mixture I have been using). As mentioned, I make RO water once per week.

I think you are right, the problem is the rockwool, it stays wetter than the stones, but I think I am stuck with it (the rockwool) as I think it would be too much trauma to get rid of it now (but I know for the next time ;-) .. Am I wrong, should I get rid of some of it? or will that be to traumatic?

I am getting a CO2 kit and will use it soon.

How many is the most buckets you have seen with a waterfarm?

How about ebb and flow?

My room is 12 x 12 and I want to max out my growth...

Thx again
I've seen my own starters with rockwool struggling to keep from drowning in the beginning.... I've just quit using rockwool altogether. Ebb and Flow, and drip are also fine once homed in. I use e/f in vegging and the drip in fowering... but there's nothing wrong with your kind of system. I know someone that's had 45 or 50 of them burping away. I believe the biggest drawback is trying to keep the temps down in the water, simply because you have EIGHT small containers (buckets) under the sun each container holding 3 gal, and lots of small lines moving it all under the lights. Where the others such as EbbFlow may have ONE reservoir of 30 not open to the direct heat of the light(s). On those pics, you can chuck the one on the left, it will not recover if its been like that for a day. The other one should make it.
