Do you lower light intensity and temps towards the end of flower?So I’m in mid flower, start of week 7 to be exact. I’m curious on when you guys start pulling back light intensity and going with a little cooler temps. I’m running a 240W S33 from AC infinity in a 3x3.
Should I be going strictly off of PAR or VPD at this point.Setup. Lighting

Switching light schedule for an auto and Phototype!I'am growing together an auto and a phototype with 20/4 light circle. For my phototype is about time to change light schedule for flowering, will my auto be badly impacted by switching to a 12/12 light? Or should I move every day (same place but no light) the photo for the night?Setup. Lighting

Mars Hyrdo TS600 - 100w but mistook for 600wI've recently found out that the led light I have which is a Mars Hydro TS600 is not in fact 600w and is actually 100w.
Do I need to compensate in any way? My plants look healthy but short, I don't want to put the light too far away that it's ineffective, how close is too close?2y ago

HLG 550 V2 RSpec power/height in flowerI’m using an HLG 550 V2 RSpec in a 3x3 tent over one Universal Kush plant. Anyone have experience growing with this light in a similar setup? What’s the best height from plant and intensity level should I set the light to? Don’t want to stress her, just want ideal light levels.Week 3

Review this model or help me create a DIY COB plus IR plus UVB grow light.I've very limited variety of lights in this country so this is all I can find. Also there are no suppliers who provide spectrum charts or any temperature values for those lights. My goal is to make it with the best possible light spectrum. Having IR's also will help on cold days.

Lamp to Plant distance - Outdoor.If growing outside, what is the best way to calculate lamp (star) to plant distance for the journal each week based on time of year and rotation of our lovely planet? I am being facetious, of course! It's just a fun question for you all. Hope everyone out there good!

Can a 1000w LED grow light be closer than 60cm (24") to a seedling?Different sources are saying: 1000w LED light should not be closer to a seedling than 60-75cm (24"-30"). The seedling should be getting 5000-7000 lux, 100-300 PAR (PPFD 18h) and 12-20 DLI.
Question: Can I put the light closer at ~40cm, dimmed to match the needed lux, par and dli

What % to keep lights at during late vegMy question was around what power % I should have my lights at? My light is 300watts so I am assuming 50% = 150watts?
Is this enough to continue vegging my plant? I have noticed the growth isn't as vigorous.
