Posible quemadura?
Every time I go into flowering, this happens to me and I can't find a solution. I use a 1.20 x 1.20 tent and I have a 730w LED; I'm starting to think that the light is too powerful and the plants are suffering from heat. There were two days when it reached 32 degrees, and I'm currently at 29/30.

dli 40x40 growbox lamp distance problem
hi guys, I have a ts1000 at a distance of 50cm they tell me to lower it to 40cm but the dli would greatly exceed (60 dli photone) the recommended threshold of 40/45. Having a 40x40 growbox, in your opinion, at what distance should I keep the lamp?

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?

Hey, why is this happening? Is the tsw2000 Mars Hydro lamp really that powerful at 50-60 centimeters? With 60% brightness dimmer? Did I add too much water? (0.3ML WATER) per plant I applied LST.

Should I put the light on before sprouting or not?
I'm most likely going to be transferring my autos from paper towel into my medium, I've heard some people say have the light on before they sprout and some who say after it's sprout, which is the best thing to do?
