I like the fact someone is actually growing something & not photoshopping massive bud shots & laying claim to them I personally don't own a
spiderfarmer but my growmie has a
SF4000 in a 4x4 tent his first run was pretty good at 480w. it is 30w. per sq.ft. not what I consider ideal but workable if you keep the plants under the lights footprint his is the early version with no external dimmer I built a 480w.cob by hacking a vipar spectra & putting 2 meanwell hlg240 h 54 b drivers & 6 luminus cobs for a total of 480w. growing the same strain we get almost identical results here is a pic of my current grow the
SF4000 in a 4x4 should work OK the difference is mine cost 1/2 as much as his & I have room to add 100 more watts
