Light
I'm wanting to get a new light and need some help. My tent is a 3x3. I'm only growing one plant at a time. How many watts do I need? I'm going through a rough patch and only have 0 max to spend.

Light question
Growing autoflowers, if you gave them 2 hours less than the recommended light; would it just take a bit longer for them to fully mature or seriously affect the yield ?

Seedling growth rate
Plants grow almost 1 cm per day (3rd week). Is it too little or correct? I have the impression that they still lack light (the rods are quite thin and long), maybe I should bring them closer to the LEDs?

LED distance in grow 80x80x160
I placed the LED at a distance of 45-50cm from the seeds and consequently it was about 65-70cm from the larger plant. I have 4 plants Is it ok like this? I don't have a luxmeter and I use the phototone app to get an idea of the PPFD in each plant. LED QB 120w, LM301H

Wondering about light in flowering stage
Is it a problem if my outdoor feminised plant in the flowering stage takes light from the lamp on the terrace just to give it water? do I have to keep it completely in the dark during this phase? Or am I just worrying about nothing?

Light Intensity/Distance for Germination and Beyond
I have a Bloomspect SL600 (85W) for one autoflower plant. I am looking for advice on light intensity/distance for germination and beyond. Currently, I have the light at 50% intensity at 14 inches going 20/4. 14 inches is the highest I can go due to space limitations. Any advice?
