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.

Low budget light I don't know if this is the right light. I'm gonna leave it for a week but if I don't see any kind of growth I'm gonna replace it with some good light. But since it's a wooden box I don't want to put a big light, maybe some stripe or bars, any low-budget suggestion is appreciated

Temporary 24 hours darkness, equipment issue.My light ballest has broken tonight, my lights will have been off for 24hours by the time I can replace, the plants are about 2 weeks from harvest, would it damage the plants to start the light cycle (18 on 6 off) tomorrow after having the light off for 24 hours?

Light strength 2 of my autos have been harvested and now I just have 1 mature plant mid flower and I've started my 3 other seedlings. I've got a tsw 2000 w/310 wts. Should I keep my lights at 100% for maximum growth or should I back off a touch to say 75 or 80%?

Hi! I have just changed to 12/12 bloomtime for my girls. I have a wifi-cam installed so I can check in on them when I want. It has night vision so there are a few red dots(led) from the IR. Can they cause trouble nighttime?

Shifting outdoor plants from outdoor to indoor So I was wondering if outdoor plants(week 2) getting regular sunlight (~12-13 hours) can be shifted indoors for faster growing (18/6 or 24/0 or 20/4)? Anyone tried before? it is safe? Will it cause to make them hermaphrodite?

Changing Lighting Schedule The days on the plants are since planting, so i was going to keep the vegetative light schedule until 5 weeks since planting, then start moving towards a 12/12. Is it even optimal for an autoflower to have a traditional 12/12 lighting schedule during flowering?

Secondary Lighting Would there be any sort of reason I shouldn't add a second less powerful light to the side of my tent? My thought is if my goal is getting more light to the lower growth wouldn't that be a good course of action?
