If you are growing outdoors and you have only 8 hours of light and decreasing, there is nothing you can do to prevent flowering now that they have started.

About the 1200w light
So I did already in fact order the 1200w led light for the 60x60x140 before asking for advise on it, which was stupid of me. Is it possible to use the light with the door open and fans to decrease hot points?

Plug timer running fast
My plug timeris running about 10 fast each 24hr. And is now at about 2 hours past the actual time. This causes the light cycle to shift forward slightly everyday. Should I set it back to the correct time, leave it be or buy a new one? It is plugged vertically in wall socket.

Does my LED need more red spectrum for flowerin?
I have an HLG 100v2 LED grow light at 4000K. They say 3000K is better for flowering. Does it make any sense for me to add some cheap red LED strips to add red spectrum? I’d rather not buy another more expensive light if I can just supplement this one. See picture.

Low Humidity and high temp or high humidity and low temp?
Do you think it’s better lower temp and higher humidity (like 27 degrees c and 80 % humidity) or higher temp and lower humidity (like 29 degrees c and 60 % humidity)? I’m just waiting for the humidifier but in the meanwhile I have to fix somehow. Thanks!

Temporary 24 hours darkness, equipment issue.
My light ballest has broken tonight, my lights will have been off for 24hours by the time I can replace, the plants are about 2 weeks from harvest, would it damage the plants to start the light cycle (18 on 6 off) tomorrow after having the light off for 24 hours?

Kind LED XL600 series 2 heights?
Hey, I’m running 2x Kind Led xL600 series 2 lights and seen people running much much lower hanging heights than recommended (18inch instead of 30inch) and wondered if anyone has any PPFD or PAR readings at anything lower than 30inch or any reasons why they run them lower. Thanks
