I am a couple weeks from my first harvest and I am using 2 GH Powergrowers. I used the Flora Series because they came with it free. The plants look good but I am wondering if there are better brands to use. I have 8 clones in 4x4x4 rockwool and the roots are starting to outgrow that medium. I need to get another drip system for these plants. Any suggestions on that? Is the Ecogrower Max good? Thanks!
