you set up is awesome looking. And 3LB per light with 8 lights wow nice.
I'm not familiar with hydrponics what I see doesn't look like hydroponic but you give a site to look at for the nutrients as for hydro's?
Could I do this same set up without Hydroponics? Maybe a little deeper soil?

You say the hoods are lR 1000's so what kind is that what brand name and model# oh I guess LR 1000?
