And yes, I understand that it's a test run. Is this one of the lights you used on last grow ? If so, we know it works !! I just don't have confidence in organics ability to feed my babies, proper amounts of what they need, when they need it. And the smell of earth juice tea is beyond disgusting !! and without something like earth juice, you wont be happy. So it's all up to Dr. Earth now !! My hydro store has a complete line of , down to earth, organics, from a to z. And it don't sound like much when you buy a box of something , but then as you get into your grow and start trying other things, and in the end, growing organicly is expensive, if done right.
