300w Led Grow Light. How Far Away From Plant?

[Jezza99]

I just started my first grow on 2 plants im using a LED but i don't really know how far to put it away at the moment its 25000lux from top of seedling. Is that good or less or more the max it goes when its close it about 80000lux

18-24" until they get 6" tall then you can go as close as no leaf bleaching or burning
