yes but when i mean results diminishing with a distance, i mean with a distance of 4 inches you dont get results.

I dont like growing plants bigger than 6 inch under my T5. i'm sure you could get em a little bigger with the 4ftx2ft model but not significantly bigger.

T5's cost an arm and a leg also. mine was 140$ for 100W
the 400 watt model is around 400$ (i think)
that’s a lot for only 400W and less lumens than an HPS by far

my fixture at 100W puts out 9000 lumens (or 8500 cant remember)
so assuming a linear relationship that’s 36000 lumens for 400W
Now a 400W HPS gets 50 000lm so 12 000’s a pretty big difference

Not to mention HPS gives off UVB light which is very good
T5’s do not
harris7 Reviewed by harris7 on . Who's working with T5s They keep calling me and I have seen other logs elsewhere where T5s are being used from seed to harvesting. Is there anyone here using them? What were your results? What were the positives, negatives? Thanks! Rating: 5
