is it okay to place it near the led lights? as many says that it could burn your seedling down.
recently im buying the 1000w full spectrum oem led from China. and i know it just “labeled” 1000w. im testing it on my plant, placing it near and seems like it doesn’t burn my babies.

Should one decrease light intensity during early flower?
Should one decrease light intensity during early flower, and then gradually increase again? I see DLI/PPFD recommendations for flowering in general, but not for the different stages of flowering.

LED's wont shut completely off
Lights seem to go on a "standby mode" instead of being all the way shut when timers switch them off. Should I buy some other timers? These were brand new, cheap ones though and both the same. Lights are HLG 600 RSPEC and both did this.

Wrong light schedule
Screwed up light timing. Thought I was on an 18/6 schedule in my tent but apparently it was 12/12 from weeks 3-7. It’s close to needing to be switched over to flowering size wise. I switched over properly to 18/6 two days ago and plan to keep it there for an extra week. Yes?

Light flashed on
Our power did some interesting things during the storm & the lights went on in the tent - I would say they literally flashed on & then off (along with the rest of the house) - during the *dark* period. How concerned if at all should I be about this? Anything I should / could do?

Seeds in 12/12
Does keeping seedlings just the first week under a 12/12 light cycle can hurt them? I have some seeds that are not sprouting after 7 days, maybe it's because the outside temperature is too low so I decided to keep them in my growbox with my other flowering plants until they start
