The Autoflower Light Schedule War Is Over (We Found the Gene)

The best light schedule for autoflowers stopped being a matter of opinion in 2024 — researchers found the exact gene that makes autos flower, and it settles the 24/0 vs 18/6 war for good. This video breaks down what your light can and cannot control in an autoflower, using the actual genetics and controlled trials instead of forum folklore. An autoflower carries a one-letter mutation that disables PRR37, the clock protein that normally makes flowering wait for long nights — so the flowering date runs on age, and nothing you do with the lights can move it. But the light sensors survived intact, which means spectrum and schedule still control stretch, canopy shape, yield, and your power bill. We cover the far-red "flowering initiator" claim (the best controlled trial shows far-red at night DELAYS flowering by about 12 days), what daily light integral actually changes, whether autos need a dark period, and the only two light numbers worth measuring at home. 0:00 The Autoflower Light Schedule War (Why Every Camp Is Wrong) 1:26 What Actually Makes an Autoflower Flower?
