Do not switch back your lights to anything more than 12 hours or your photo period plants will respect that photo period and go back to vegging stage. Keep on the great care! Happy smokes!

Light timer Problem
Hey Growers. So I made a dumbass mistakes…..for the last 18 days I have had my light timer set for 12 hrs 15 mins on and 11 hrs 45 off. They are looking good and budding up. I’m wondering is that close enough to 12/12 to have my day 1 flower be true for accuracy sake. Thanks

Light question
Growing autoflowers, if you gave them 2 hours less than the recommended light; would it just take a bit longer for them to fully mature or seriously affect the yield ?

Can you use a 450 watt white led light to start seedlings? If so what distance should the light be and when should I make it closer? The reason I am asking this is because I don’t like transplanting autos as they are fragile to transplanting from what I’ve looked up

Short period grow
Hey fellow growers. So I have an odd question, Is it actually possible to start grow with 12/12 straight away? And how will it affect my plants? Let's say I have 3 autos and one photo. Will I have anything worth the time if I start straight with 12/12 light schedule? Thanks you

the light came on by accident at night
Hello! The light in the grow box accidentally turned on for 10 minutes while I was sleeping. Is this too harmful for the two autoflowers? Will they become hermaphrodites?

Which strategy with auxiliary grow Leds ? 3x20w Leds -Thanks !
Helps maturing but I wonder if buds are bigger. I used to put 3 extra lights 20 cm below canopy, leave many large leaves at the top and lollypop 30%. 30% is definitely not enough even with those 20w LEDS (50% is probably better). How do you use extra LEDS ? Where do you put them?

Light burn
2 fairly new leaves at top (opposite ends) seem to show signs of light burn (yellow tips). They recently turned a bit more green but the tips are still quite yellow. Light = 13 inches away. PAR 370 at center, 350 on sides. DLI=~ 22.5. CO2 bag in tent (at about 620). Thoughts?

Will this be enough for 2 auto flower plants in a grow tent? Or will it work for one? The tent is 20x35x64. Or should I get another one or a different light altogether? Thanks!!
