Distance from bulb or from reflector?
I found content about the distance from grow lights to the plants. I Know that using a 250w MH bulb the distance should be in a range from 20cm to 30cm. But i dont know If I should measure the distance from the glass of the reflector or from the bulb itself to the plants. Help!

Light timing
My plant has sprouted today, when should I switch my lights to 18 hours and not 24? Also how often should I be watering? Just so the soil around the plant is damp or? Any help appreciated! First ever grow :) blue dream auto 1

Mars Hydro TS 1000 [3500K,100W, LED light] (Plants @ 3
Questions: See photos. 1. MARS Hydro TS 1000 will not support 4 cannabis plants, correct? Support = Obtaining full plant potential. 2. The Chinese 3000K lighting won’t “hurt” my plants in veg, right? It’s just simply isn’t the lighting that works for veg growth, yea?

Light Science
Has anyone watched some Youtube videos by Dr Bruce Bugbee from Apogee Instruments? I find his lectures on lighting to be the most straight forward explanations I have heard yet. I found his vid called "The New 400-750 nm ePAR Range Explained with Dr. Bruce Bugbee" to be eye opening on lighting colours. I have changed my LED's based on a few of his vids. He explains what plants really want and those Burple lights just don't cut it. For those that don't know he is a professor at the University of Utah that legally studies cannabis growth. He takes the science of weed grow to a whole new level.

How can I prevent these light burn issues?
It seems these Mars hydro lights are not so great. This is my third grow and having the same issue every time. Red stems where they are exposed to light. Yellowing leaves. But when I move the lights further away, stretching is very bad. Should I just get new light?

White and blurple led in same tent?
I recently upgraded to a TS1000 for my flower tent, and am waiting on an SF1000D for my veg tent, and now have a tmlapy “1500w” blurple sitting around. Would i gain anything running the blurple and ts1000 in the same tent? Or is it not worth the extra energy consumption
