The 2 SC are trying to push out of the rooters. I went ahead and filled the reservoir, added the nutes, and turned everything on except for the chiller. The res held 9 gal and another gallon in the reserve tank. That's a lot of water and I have to do that every 2 weeks? I think that I use about 30 gallons for the whole grow when I do 2 plants in 3 gal pots of soil. I put the rooters in the net pots with the pebbles or whatever they are. Hopefully the girls will have their heads up in the morning.
