I was going to run it just like the 300 watt Mars Hydro FC E3000 and 150 watt ts1000. Seedlings 24 in, vegetative 18 in, flowering 12 inches. I also have a 400 w MH / HPS wing reflector I may throw in.On the heights and % I am curious how you run the Mars Hydro?
Unless there is a tremendous difference between the two cheap Chinese lights [ I run Mars Hydro ] I suspect the SF will run the same or very close to how you run the MH ?
No experience with SF so maybe just thinking outloud ...
