Flowering

Considering ruderalis plants evolved to grow in the Arctic Circle, everyone's "natural biology" argument for a dark cycle for autos is completely horse shit. These plants are made for 24 hour cycles. That being said, as long as you're providing enough light it doesn't really matter.

Hello! I disagree with some things that has been said. You can without a problem grow a Automatic plant with 24h of light. There is more than enough proof out there, to show it. Would i recommend it? no. For Automatic plants i always go with 20h of light and 4h of darkness. The important thing is to have more light with automatics than you have when using photoperiodic plants. Because automatics don't care and still go into flower with more than 12h of light they can develop quicker as photoperiodics which is why some strains only need 9 weeks from seed to harvest (did them myself) what would be unimaginable for photoperiodics because tey simply can't get more than 12h of light per day. More light = more photosynthesis Why not 24h? Because most of us are far away from being the perfect grower and light out means recovery and repairing. without that you can't afford to have any issues at all. Thats why i go for 20h light 4h darkness from seed to harvest in Automatics 16h light 8h darkness for Photoperiodics in veg and 12/12 for photoperiodic plants in Flower ( thats just my opinion(: )

You can run auto for 24/0, but I would suggest 18/6 or 16/8 for stress release. In general, the plant needs more red shifted light (autumn light) for potent buds.

NEVER grow at 24/0..............18/6 is optimal. ALL cannabis plants NEED "sleep" for a correctly functioning metabolism. A plant with an incorrectly functioning metabolism will never produce best quality/results. The fact some people say it is ok to grow at 24/0 is a biological error.
