Start at 36"inches and work your way to 18" as the plant grows.

LEDs lumens
is there a method (which does not involve the purchase of a rather expensive device) to measure the lumens present in the growbox? I would like to make sure that the LEDs that I bought have the same performance declared on the package 😕

Should I put the light on before sprouting or not?
I'm most likely going to be transferring my autos from paper towel into my medium, I've heard some people say have the light on before they sprout and some who say after it's sprout, which is the best thing to do?

Grams per watt
What’s the best gm per watt that someone here has gotten on a single plant? I’m aiming for 1gm per watt but doubt that she will yield 315gm once dried.

Distance from plant to lamp
I’m growing under a 200W LED light... how close to the light should the seedling be? Right now it’s just about 90cm / 35 inch away from the plant.

T5 vs. LED for veg?
So I have a T5 light, and I’ve used it to veg quite a bit, and it does really well. My question is, should I use the T5 in just the seedling phase, then use LED for veg and flower? Or will the T5 give me good results throughout the veg cycle?

Electrical power calculation
Actual power consumption of lights is lower than led manufactorer says. 25 leds of 3W each = 75W plus an internal fan plus some other circuits,Total power should be more than 75W and i calculated 58.3W overall. Vac=220 , I=0.265A Any ideas?

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?
What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?
