Has anyone ever moved a plant from HID lights to LED during flower ? Keen to hear from your experience as it’s looking likely that I’ll need to do exactly that in the near future .

Yes it can be done. A lot of times you may need to add a little more cal mag is about only issue. Plus Temps won't be as strong. Good luck. 🌱🌱🌱

Setting up air cooled refactor.
I've got a new air cooled light refractor, a tube like one. I've set it up such as the pic, I'm thinking of putting the extractor where it shows on the pic with the air flow going the way of the arrow, would this be OK? I can't find anything online about setting this one up.

light intensity for clones right after transplant ?
basically should you treat them like a early veg ? using migro 4 array and it recommends 40 percent intensity at 35 cm away for early veg. or because they are just transplanted should I give them a lower light intensity.

Cloning area lighting
I have a 4x4 tent that has 2 plants growing, and 1/4 of it I wanna create a little box that light cant get out if for clones to grow, and set an LED in there. If I take clones, set my main plants to flower, takes 4-6 weeks, how much light is needed for the clones to survive?

Back To 24 Hour Light - Auto Flowers
My autos switched from 24 hour light to 16 about 2 weeks ago to see if it would help make them bloom faster. Can I turn them back onto 24 hours or could that mess things up? I would like the most amount of light time. They should have 2 more weeks left

IR cameras and ligth
Are IR cameras dangerous for the night cycle? I have my plants on streaming and I'm thinking of placing an infrared camera and IR LED I'm worried that the IR light can stress the plants and interrupt the night cycle. Wave you experience this with security cameras?

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

Is that just a light burn or could it be something else?
One bud in the middle of my plant is much lighter than all the others, which all look healthy and green. I think it was due to the too small distance of my light, which was only 20cm (8") between canopy and light. I have now moved the light to 35cm (14"). What are your opinions?

Heat, RH or overwatering? Or alltogether?
Hey my fellow growers! The grow reached 32Celsius the last 2 days in the last hour before going into night time. On that time RH goes down to 32% and this seems like it's stressing this lady a bit. Yesterday fed her nuts - maybe a bit too much? Thank you for stopping by!

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

Will increasing light intensity restart stalled seedlings
Seeking advice from Mars Hydro TS1000 growers. When do you increase light intensity during seedling stage? I've had the light 30cm above the plant at 25% power since germination. The plants stalled 2 weeks ago. Can I get them going again by raising intensity or will I fry them?
