I dunno.. but I have Lowryder #2 (dr chronic) under 24/0 with beautiful flowering.. but I had to move the Ganja Dwarf (ams seeds) to 12/12 before I could get it to flower...
But I imagine the continuous light versus 12/12 would yield better results! I got about 50/50 males/females for both strains, but I would still recommend lowryder over ganja dwarf.
Here are a few pics.. The first one is the Lowryder #2 under 24/0 (blue) light with 5 in white pots.. then 2 closeups of the white hairs.
Also.. the LR#2 were planted 3/31/08 and not too sure about the GD
but they were put to flower on 4/9/08 though they are a few weeks older than LR#2. I think the GD have 2 weeks left, maybe 3 max. Supposedly they finish in 2 months, so the LR#2 should finish around 5/31/08.
The orange tinted pics are the GD in the flower room to give you an idea of what it looks like. These are grown under 400w HPS/MH with CO2 generator.
