Search online for Daily Light Integral (DLI) chart. The chart shows PPFD and hours per day. Then you can pick the light level based on how many hours you run the light.

Anyone have any history with vibrating HPS lamps? Mine keeps making a buzzing/rattling noise. I’m thinking it’s the metal inside rattling on the glass so if I slightly rotate it it may stop? What do you think? Thanks!

11/13 for flower
I need my grow to finish flowering ASAP, due to extenuating circumstances... I’ve read that flower can occur faster under 11/13 with some loss of yield. Does anyone have experience here? How much will yield and flowering time be influenced?

LEDs for 32x32 tent
New to indoor growing. Set up a 32x32 Vivosun tent. Currently have a giixer 1000w light, but wasn’t feeling the coverage was good enough for several plants. So I just ordered a second one. Do you think 2 giixer 1000w leds is ridiculous overkill? Any thoughts appreciated.

Hi guys, My LED light from my tent just stopped working, it might have been the humidity or straight water in there. The new lights might arrive 4/5 days to arrive. Do you think my plants are going to die? you can check my diaries if you need. Thanks for your help.

Increase light hours autoflower
My autoflowers are 6 weeks old and showing flowering signs. Can I increase the number of light hours from 17hrs to 20/22/24hrs? Does it cause light stress and can trigger vegetation or make it hermaphrodite?

what is correct light schedule for indoor germination and seedling, and then transplant outdoors?
I plan to grow a photoperiod plant outdoors from spring to fall, but the germination and seedling stages will be done indoors. For the indoor part, can I use a setup with 18 hour light schedule? Or should it be 12 hours? I don't want to trigger flowering when I put it outside.

Can I switch my lighting schedule ?
Hello everyone. 1st grow here. I'd like to swap my lighting (automatic plants) from [4am:midnight] to [4pm:noon] just to keep the temperature a little higher at night. Is it doable while not hurting the ladies or should I shift it an hour per day to change the cycle ? Thanks !

hi guys, I have a ts1000 at a distance of 50cm they tell me to lower it to 40cm but the dli would greatly exceed (60 dli photone) the recommended threshold of 40/45. Having a 40x40 growbox, in your opinion, at what distance should I keep the lamp?
