LED COBs and maximum scrog height possible?

Hello. I am going to run COBs (cree cxb 3590) @ 700ma to 1000ma, what could be the minimum distance between scrog and my lights?
I am willing to make it easier and make a non adjustable scrog, but if it is necessary, I will try to make it adjustable.

I go 6' tall, but I'm not very ambitious.

Where are your lights?

My max height is 180 cm
I should probably hang it in 4 chains. Will weld a frame and then add reinforcing rod sieve as my net. And paint it white ^^

At 1400ma without reflectors I can get buds as close as 6-8" from my light without issues. At 700ma you should be good to do the same but if your using reflectors or lenses you might want to try further away. Just make sure you can raise or lower your light.

ttystikk grows vertical. The lights are out of shot to the left.
