FCE-4800 at 100%???
does anyone have a fce-4800 by mars hydro and possibly have it in a 4x4 tent? Do you crank that bad boy up to 100% in flower or is it too much?

Would there be any sort of reason I shouldn't add a second less powerful light to the side of my tent? My thought is if my goal is getting more light to the lower growth wouldn't that be a good course of action?

UV rays - Is it worth
So guys, what are your thoughts about UV light complementation? Earlier this year, I havested an auto flower, and she dind't bulk up the trich production. I ended up with big flowers but with no effect at all. I was wondering if that has something to do with my light setup.

Added a light, how far should I hang them both from the girls?
I have added a Mars Hydro TS600 to my tent along with the Spider Farmer SF1000 in my 2x2, how far should I move them up away from the plants? I'm guessing I don't want them as low as the SF1000 was on its own which was around 15" Thank you lovely people!

Light schedule
I am doing an outdoor grow and also have a grow room set up for germination. Outside is only getting about 14 hours of light, is it beneficial to bring my girls in under my LED's for 4 hours to make sure they're getting a full 18 hours of light? then bring them back outside

Short plants in flowering
Flowering started but the plants still seem a bit short. Maybe too much or too close light? Or something else? Tried avoiding light off because its hard controlling the rise of humidity.

Light Distance - 3 plants are taller than the others...
Hi all. So I have 6 plants with a 400w HID. 3 of them are about 10-15CM taller than the others. My light is currently about 45CM from the top of the tallest one. Would this affect the shorter plants negatively? Should I raise them to the same level and up the light to 60CM rather

I ordered a lamp from Amazon, it probably won't have super performance, but I thought if I ever do flowering and still have a few seedlings, I could separate them. What do you think about that? Right now, it's just serving as support.
