3200k my personal or 5000k a mixture of both would be Ideal I don't know why you would want to only chose one though. This is all LED based I assume are you counting MH bulbs they can be very good for vegative growth just expensive to run.

Danger of Humidifier
Good morning everyone. So I've recently set up my new TS1000 and I'm wondering is humidifier dangerous for LED lights? It's directly under the light 60cm. And how can I regulate the temp in the room without new equipment? It's too high at the moment.

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.

What kind of light level (lux) during the dark cycle will cause my plants to herm in the flowering stage?
What kind of light level (lux) during the dark cycle will cause my plants to herm in the flowering stage? I am growing in my bathroom (no windows) and I am worried about external light entering. My bathroom has 3 LED (30W) bulbs in, I have removed the 2 closest to my plants.

WHAT IS CAUSING MY LEAVES TO CURL? (Day 64 pictures)
The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏

Light pointed at white wall for supplemental lighting?
Does it makes sense to have a small 300W COB LED pointed at the white flat painted wall for supplemental lighting? If I point the light directly at the plants I would surely burn them but have no space to move back.

Lighting. Increase or stay the same?
Hi, I'm thinking about increasing lighting to 100%... is it too soon? Currently at 60% 20 inches away (manufacturers recommendation.) I'm thinking 100% but staying at 20 inches away.. what's your thoughts? Too soon? (12" - 18" 100% for veg manufacturers guidelines)

Extra belichting
Hello. I'm in the third week of flowering with my royal gorilla plants, they're under a 600-watt HPS lamp. If I were to add an extra 400-watt lamp now, would that increase the yield or be a waste of energy? Regards, Gorilla
