thats .8 gram per watt with the 310w led with a Platinum GSCx Blue Dream.....really low yielding strainis that your first run on the strain?just wondering because the math comes in very low compared to 600 hps,which would be less than 1/2 gram per watt. i do want to try making fixture or 2 at higher currents like 1750 or 2100 when and if i can get my hands on some larger pin sinks.
with a 400w hps in that space I got .4 gram per watt
the thing is I dont measure gpw.....to me it's nonsense
a better measurement is grams per sqft
I also like comparing watt for watt
so I look at what I could do with 400hps in a certain sqft....then compare to an led fixture that is 90 watts less and I doubled the gpw...
but again IMO gpw isnt a very good measurement
for me...I really like to maximize the space that I am growing
if I add 2 more cobs that will push my watts to 450
judging by what I just netted from 310
2 cobs will increase my yield from 253 g per sqft to 334 g per sqft
essentially netting me 166 more grams per sqft with only 50 more watts then a 400hps
which in that space only nets me 14 g per sqft essentially .42 gpw....remember this is a super low yielding cookie strain
I am sure if I grew a commercial strain like Big Bud....I would be destroying my space....but I grow connisuer strains which some are very low yielding....but the quality and effects....for me.....are what I am after with the strains I grow
