well i am about to start my 2nd run of home made super soil for autos
if u like i can tell u how to make one fill your whole area

its a great light, antics did a side by side comparison of their 300w models and the platinum grew 2 more zips. I dont think LED is fully sufficient though, HPS is still going to be the bread and butter till COB gets more developed, but its really nice to have the broad spectrum, this light gets really bright with the bloom switch on!
