First Flood and Drain grow attempt. Popping 4 Mephisto Sweet n Sour autos. Using 6x6x6 rockwool cubes. With Optic 1 Cob led. 1 Viperspectra V300 and 1 viperspectra R300. I have already ordered 1 more of each. Im also using a TDs and ph probe continuous meter for my reservoir. Just waiting on seeds to germ. Then I will place them in 1.5x1.5 rockwool cube until they sprout or I see a root poke out. Then I will place in bigger cube.
