My friend is new to growing, he is going with 5 ES plants in soil under CFL's. Things seem to me coming right along. He has 5 plants under 4 CFL's, 1 LED array and 2 2' flouros. Now I was gonna say he should get one more bigger light, (ie 105w CFL).

I would like to know the answer to your question about when to flower. What height?
