You could, however you will see reduced yield, autoflowers do best with 18-20 hours of light a day. Happy growing.

First grow tips and strains pls?Looking at starting my first grow, I have a 120x120x200cm tent, and a 1000w LED light. What auto strains would you recommend for a complete beginner? Any tips in general would be great too. I'm hoping to have 8 plants, but generally quality is more important to me than quantity.Setup. Strain - Autoflowering

Erratic light cycles for the first weekAny experience with keeping a seedling in 12/12 to begin with, then switching over to 18/6 after the first week? Because I did that this time for tech reasons, and I do wonder if I produced a hermie. My own notion is that it will just set me a week back perhaps. Anyone know tho?6y ago
