The light is to far away. You have a dimmer so you can put the light closer and run it with less power.

Light intensity for 2.5 week auto flower
Can anyone recommend how high and what percentage to run my light. The leaves have not been strongly perked up in a few days and I wonder if it's that the intensity of light is too high. I've been at 80% at around 14 inches. vipraspectra p600. Critical purple auto.

Lightning question
Hey, Growers! This week I had to open together the two boxes, so now all the plants have both kind of lights. Do you think, it can have a negative effect on them, or maybe it's good at least for the 140cm height White Widow,because the bottom parts get some more light from there?

Not enough light? Help?
I think my flower is not getting enough light. How can I make do with the light on my balcony (that only hits the plant from the side for about 6 hours a day). Any tips or tricks for increasing yields in my "lightless" situation? (Growlights are out of the equasion due to space)

lights
Would I benefit turning my lights on from veg to bloom at an early age with auto flowers? Or would it still be too much light for them?

Is my lighting too high
As can be seen on first image plant leaves got trapped inside seed casing for a day or 2 before it fell off, not sure if I have my light to high as my plants steam is 3+ inch in length

I need help choosing a better light for my single plant microgrow!
H50cm W37.5cm L57cm Now using 1 household 13w Phillips LED 2700K for flower, a 120w CFL for veg and I use a cheap 20w dual Spectrum LED that I'm sure does almost nothing. See pics for convo with led sales guy. Is the height really that much of an issue with the light intensity?

Looking for unsponsored responses... need light...my car cost 1000$ and I can't justify anything close to that. Flowering a 4x4 area..should I wait for tech to develop and HPS in the meantime? Convince me otherwise with your experiences! #budget

Stretch to the light
How can you tell if your light is to close or to far? Is this gal stretching to much? Should I have increased the dimmer and/or lowered the light earlier?
