Lighting Fusion boards

[stonehead]

I have 4 fusion boards in a 80x80 tent but wondering how many watts and what height I should run it with 4 autos on a 20/4 schedule?

Started at 300w but seemed abit much so nicked it down to 250w.
Light is sat at about 30” above the plants

Thanks guys

I would run them at full power and just adjust the height... what age are the plants at ? .... in full flower you could be getting to some where between 18" and 12" depending on the plants.

stay around 21" , then as they get bigger let them get closer. Like I said before in full flower your want to be about 18" to 12" maybe even 10"... It really depends on the plants
