these were grown from seed. don't know the lineage. I can tell you for a fact that at 11,000 lumens/square foot you beter keep them at least 8" away. Just too much UV Radiation. If you kept your hand a few inches away for hours all the fans you could use would not keep them or you from getting Burned.
Manyk Myke Reviewed by Manyk Myke on . First indoor CFl Grow I really need some help. These are maybe 8 weeks old in 1 gal pots under the cfl arrays 24 hrs/day on for 3-4 weeks. Maybe I went over the top 8-9000 lumens/sq ft. 65 % 2.6K, 35 5K, have them in miracle grow and given nothing. Have huge stalks and just waiting to take off I hope. Leaves brittle and browning from heat? SAVE ME Rating: 5
