Time lapse under HID lighting
Demosthenese
started grow question 4y ago
How do people do time lapse with hid lighting? Do I need to set timers to turn off hid, turn on fluorescent and then take the picture? Is there a filter I could buy that eliminates the horizontal scanning lines?

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.

Bloom Light Supplement
I am a one plant windowsill grower, but having trouble getting enough light for bloom due to cloudy days. I have a three prong red/Blue LED light off Amazon, Wakyme, that is not cutting it. Would this lamp work? Two bulbs. I will have to suspend it from a clothes rack.

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,
Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?

SF-1000 safe distance and dimmer for seedlings in soil?
my seedlings are stretching and not growing in size. soil, autos, dropped in water 7 days ago and moved to soil in solo cups. What are people running the SF-1000 at for seedlings? I was at 30" and 20% but that's not good clearly. I've moved to 24" @ 45% so far.

LUX meter grow question
Can someone check out the LUX meter video and tell me how I should be positioning my lights? I think maybe I have too much light on them. My meter says 600 (x100) that puts me at like 60000 lumen. The converter I used put that to 1541.36 umol/s/m2 which is a lot of light already

Thoughts, good idea or bad idea?
I got an idea from when I was pruning pecan trees growing up. If I install small LED lights directly inside each "window" or "pocket" will that improve total light and production, or will I just burn the plants?

Is anyone else using Spider Farmer Lights ? How was the stretch on your plants using these lights ? My plants stretched from 10 inches to 30 inches in two weeks & another week of stretching left.😒 Not a big deal but I have a 60 inch tent , not a lot of room to LST.
