im sure i read before ideal instead of having 6500k bulbs then switching on flower as its autoflower to have a mix? 3 my "spare" 6500k bulbs dont even work so ive got 2 6500k and 1 3500k should i keep that throughout?
the 3500k is useless because you need either 2500k or 6500k, so a lot of thw wattage isn't being used by the plant.
autoflower strains still grow better when you give them flowering conditions (like 12/12 or flower nutes or better suited lights etc..) during flowering, even though there's no specific time to switch over. switch the light when the plant starts to show signs of flowering.
i'm not sure abuot that actually, and i've never grown an auto, a lot of people say you can give as much light as you want because light cycle is irrelevant to an auto. so some give 24/0 or 20/4 throughout, whereas others say you should still stick with 12/12.
you should just do both in two grows and see for yourself because it's the only way.
Maybe ill try 18/6 throughout then try going down 12/12 flower next seeing as only 8 weeks ive never grown autos either so new for me going to start journal hopefully pick up some help along way hoping to get 14 min g per plant have heard alot of 25-35g per plant grows
