18/6 or 20/4 there is no need to do 12/12 and will only hurt your yield. Hole this helps good luck

Seeds in 12/12
Does keeping seedlings just the first week under a 12/12 light cycle can hurt them? I have some seeds that are not sprouting after 7 days, maybe it's because the outside temperature is too low so I decided to keep them in my growbox with my other flowering plants until they start

Does my LED need more red spectrum for flowerin?
I have an HLG 100v2 LED grow light at 4000K. They say 3000K is better for flowering. Does it make any sense for me to add some cheap red LED strips to add red spectrum? I’d rather not buy another more expensive light if I can just supplement this one. See picture.

Light burn or nutrient burn?
Hey guys. The tips of my leaves are starting to turn yellow and I’m wondering if this is a nutrient burn or light burn? I lowered my ppm feeding to about 250 a few days ago and am growing in ocean forest fox farm soil. And the light is an optic 2 running just the cobs at 24”.

Can a 1000w LED grow light be closer than 60cm (24") to a seedling?
Different sources are saying: 1000w LED light should not be closer to a seedling than 60-75cm (24"-30"). The seedling should be getting 5000-7000 lux, 100-300 PAR (PPFD 18h) and 12-20 DLI. Question: Can I put the light closer at ~40cm, dimmed to match the needed lux, par and dli

Voost VST240
Looking for a good budget light for a 4x4 grow. The Voost VST240 looks like a fantastic spec but no real information out there that I can find. Any users? Also considering a Migrow Array when the bigger version hits the market.

HID 600w ?
I'm currently using 400w in my 1m². Do you think it's worth switching my bulb to 600w? Or is that too much for 1m²? I'm going to switch to flowering next week.

Light Intensity
Hi there! Last week I discovered that plants were very droopy. It was end of the day cycle so I dimmed the lights around 400 ppfd. Normally I would give easily 700-800 for 18 hours. Why is that happening now. Is it that my co2 ppm is very low? is it genetics?

Pruning?
Pruning ideas along the stems? Was thinking that some of the branches at the bottom that may never get over the lid of the pot should be snipped off. Also, good idea to keep blue/red light shining under the canopy?
