Hi, wondering is you guys could look at my enclosure and give me some ideas as to when and how I should provide some air circulation to my seedlings? I plan to keep them in here for the next couple weeks like a small grow room. Also, do they look happy for day#3? Advice? Thanx

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?

LED light distance
Hey guys I'm kind of new to growing only been doing it for a little over a year. My girls grow really well they just don't get very tall I'm thinking it's because my lights are too close. Is this correct? Distance is 9 inches above canopy in week 6 growing critical 2.0 autos.

New update got my new grow light dialed in.. And the nutes helped a lot seen more growth in one day than I had in the last 23 days! I am worried that if I place the light at the recommended height (6”) that would be too much so I’m running the lights at 50% power and at 12” away

Help with issues ID
I have a photoperiod in a 5 gal using BAS light. It is currently day 3 of week 4 , and I'm getting some damage on the tops. Would this be light stress or another issue? The tips are starting to go light green. Using the 200 watt light for the 2x4x8 ac infinity tent.

Lowering light
Should I lower my lights and decrease the intensity to get better penetration or keep them the same height and increase intensity? (These are auto flowers about 50 days old getting towards the end of flower)
