KingBright 240w Meanwell driver relocationDoes anyone know the name of this connector the Kingbright LED boards use and where to buy them? I'm looking to relocate my LED driver but Kingbright wont be able to get me one till August. If I could at least find compatible adapters I can make my own cable out of them.Setup. Lighting

My grow tent is sitting in my basement, which normally sits at 10C in the winter, so I set the heat in the room to 18C and the LED and 2 fans heat it to 20.4C in the tent.
Anyone have a similar setup but using their grow lights as a heat source? Heating a basement is expensive.Setup. Lighting

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. 🙏6y ago

Will increasing light intensity restart stalled seedlingsSeeking advice from Mars Hydro TS1000 growers. When do you increase light intensity during seedling stage? I've had the light 30cm above the plant at 25% power since germination. The plants stalled 2 weeks ago. Can I get them going again by raising intensity or will I fry them?Week 4

How to measure lumens of a full spectrum LED light.Since a lux meter only measures certain spectrums of light, how do I use a lux meter to determine the right height of my full spectrum grow light?
