I have several question about my setup for the first week:- is the distance of the light to the plant ok? - is the intensity of 25% correct? - should I remove the seed coat or should I just let Mother Nature do it, eventually it will be blown up..

3000 watt power use This is my first time using such a powerful light in my opinion, 3000 watts seems overkill but that's what i want. The question IS, is it better to have 1-2 plants under the 3000 watt or worth it to manage 4 at a higher distance? Cheers. Don't keep techniques in mind.

18/6 leads to high temps in small tent; change light schedule or stick it out?Girls are at 18/6 and 3-4 hours before lights out the tent gets up to 90 degrees and humidity can’t compete. Should I wait it out or try 16/8 moving towards 12/12 close to flowering (autoflower). Will lowering light exposure affect yield more than high temps would at 18/6

How to switch to flowering It's been about 5 weeks from germination. I think we're ready to switch to flowering. I'm just not certain on how to go about it. Do I gradually reduce 18/6 of the veg light down to 12/12 (over a week?) then pop in the flower bulb? Or do I just make a hard switch?
