Started with 6 seeds : 2 Gorillas cookies, 2 Blue Hell, 3 Mohan Ram: 2 failed. I restarted 1 SAD and 1 Killer Kush.
Finally 7 plants in the grow tent under a Niello 300, vegetation mode (blue light). This light consume 120W , no heat generated; it’s a good option for September/Octobe with cool temperatures.
