Which LED light for 2'x3.5'x5.5' perpetual DWC autoAfter this run I think I'm going to grow 2 DWC autos at a time and harvest monthly. I'm looking at a 6x 3k COB, a 58 SMLEDs 2 CREE COBs (3k and 5k), or a 112 SMLED and 4 CREE COB (3k).

Do I keep dimming my light to try to get proper DLI?Currently at 22" above soil at 50% intensity and still getting ~50DLI at Germ/Seedling stage (too high?). It's a 240W LED. Do I keep dimming the light or do I change light schedule (24h currently) to get proper DLI?Setup. Lighting

regarding the light spectrum ratio. what is the ideal light spectrum for both the vegetative and flowering phases?
Do you use 3500K lights during the vegetative stage, or only use cold white lights at 6000K? do you then switch in flower to 3500K lights along with 370-780nm?Setup. Lighting

NEED MORE LIGHT!So as of right now I have 1 400w mh/hps light in a 4x4x6.5 tent. I know for a FACT that I can have way more light inside this tent. But my question to you guys is what kind of light do you think I should put in with my hps? Would like to have around 1000w or equivalent in PARSetup. Lighting

Does anyone have experience with colas that have been severely light deprived, yet still have trichs?My ghost nug grew up on the side of the tent blocked from light. She has trichs, looks super light yellow (see pics). My question is, wouldn't this be desirable? Less chlorophyll to wait on before smoking? Has anyone tried to maybe light deprive parts of their colas?6y ago

LED Kelvin Temp 3000k-6500kIs there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.6y ago

Mars hydro 600 lights not going fully outHi everyone
I'm having issues with my LED mars hydro 600w when the timer is going to 'off' the lights are still very dim, with the plant being a photo period I'm worried the dimmed lights won't let the plant sleep and shock it or keep it in veg. Has anyone had this issue?Setup. Lighting

using both veg and bloom switch toggeled to on with led light during flower questioni was watching a video on youtube and the person was using an led light which had separate toggle switches for bloom and veg and during flowering of autoflowers he had both switches on and was wondering if that is better to have both on and if so is it only good for autoflowers?Setup.

Lighting questionI am running the Viparspectra 450w LED as my light for 4 autos in a 2x4 space. I am worried this isn’t enough, especially because of its lower levels of red. Should I upgrade to something stronger like a Mars hydro 600 or 1000 before flowering start?Or if not Mars something else?Week 4
