How to tell if light is damaging plant?
TheBonnieRobinstarted grow question 4 years ago
I'm using a Mars Hydro Ts600. Manufacturers advice is to keep height at 12'' minimum above the canopy in flower but other growers report it can hang as low as 10''. In identifying optimum height how would I be able to tell if it was too low for my plants? What should Iook for?

The Ts600 is only a 100W designed for a small space, if you want to check how far you can distance your lamp from the plant try lowering the lamp to as low as 8-10 inches (seems like you're in flowering so I'd try going with 8) and check you plant regularly, if she shows signs of radiation/light stress (foliage starts to fold and curl upwards starting from the top of the plant) then move the light 2 inches higher!
Also don't forget that in flowering the plant needs more light to produce fatter and denser buds!
*I started using the TS600 as extra lighting during flowering, I got it set 5 inches from my plants and they're doing completely fine! it all depends on the plant and what stage of growth she is in.
Hope this helps! Good luck and happy growing :)

Sometimes the first signs to much light is leaves pray to the gods, cupping of the leaves, tips turn yellow like nutrient burn, and most common leaves are paler closer to the light. But to actually know how much light your plant is getting is a par meter

Leave tips will turn yellow and it will basically bleach the leaves yellow from outside in. I would not do 10 ot 12 inches. More of 24. My ts 1000 lights are bright and I do 24 inches if not more. My results have been good on lighting. Can also get a cheap light tester to test ppfd. If over 2000 you will cook the plant. I hit around 1200 to 1600. Is my max I push.

When to lower light intensity?When is the right time to lower light intensity? I'm on 5th week of flowering, should I keep my lights on max or reduce the power/increase the distance to plants? I have around 1000W of Led's at 35-60cm distance from the tops. I see no burning/bleaching or anything like that.

Lifespan of led grow lights?Lifespan of LED quantum boards?
Hi
I'm looking for anyone who has first hand experience with the lifespan of the led grow lights. I'm not looking for the manufacturer guidelines. Just anyone who has noticed any difference in performance from the LEDs over time..

Best Light Schedule for Autoflowers?I'm wondering what light schedules my fellow growers like to use with their Autoflowers? I'm debating weather the additional cost of a 20/4 is worth it in terms of growth and increased Bud Quality/Size over a 18/6 schedule. I would love to hear your experiences.Setup. Lighting

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt fI'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓
