No, not with the auto's. They need the veg. spectrum their whole life in order to do there best. If you were to grow auto's outside, your first grow(end of April to the beginning of June) and your last grow(August to the end of Oct.) will be about the same, but your middle grow(July to end of Aug.) (when the sun is at it's strongest months) will out preform the other two grows. I hope that makes since.
Are you going to collect the pollen from your males to pollinate females for seeds later on? Hang in there, that's part of the game dude-et. Try gemming your seeds at 73 to 75 degrees. Cooler temps. help to germ female plants. Same with the temps. at the seedling stage. Keep them cooler for females. Not fool proof, but it does help. I don't know how you germinate, but I use a propagation heat mat with a thermostat that plugs into it. I also start my plants in a 12 plant jiffy greenhouse w/jiffy plugs. Now I'm not saying I get all females cause I don't, but like I said, it will help.
