How far should 90w ufo be from seedlings?

[dexter68]

im on my first grow using the 90 watt triband red;blue;white.ufo led lights can be almost touching your plants and not burn.ive used mine from day one on autoflowers,and they are and have been wonderful.no heat signature.no burns.electric bill normal,and my girls love the light.best done i believe in closet, or similar space cause led lights expensive if more than one or two are required.

Works soooooo much better than my stupid rubbermaid grow box stacking contraption. Anyhow, seedlings are about an inch tall now in thier humidity dome and seem to be doing well. Today is about six days from putting them in paper towels with 100% germ rate. Sweet! On to my question. How far should the ufo be from my humidity dome? Right now its about 18 inches away and temp/ humidity is 90/90%. Perfect! Temp outside Rating: 5

From the information I have seen you can have your plant as close as 1 inch away from a 90watt LED, but the optimum range is about 3 feet.

Hope this helps.

Ok straight led. Hope youre right, gonna be pissed if my girls die lol. :thumbsup:

No worry, brah.
'Shake gives good 'vice

And, in answer to , how high?
That depends.
If you want stretch, up to 3'
If you want short internodes, 3"
A good compromise is 8 - 10"
Mind you, I only use 2 colors now and sold my 2 band Ufos to buy 15W. emitters
Your mileage will vary so experimenting is advised..

It's not that 4 bands 1W. emitter lamps are bad.
Just not good enough.

You can 86 the cfls.
They made little difference with my lights.
And you are already wasting Watts on white leds. <- Opinion.
