Thanks to WeJuana, and all the other contributers to this thread, a great read and very helpful and informative.
I do have a couple of questions, maybe you guys can help me.
Of the results just published above, the overall yield appears to be +/- 60gms/plant, multiplied by 5 to each tent? equals around 300gms/tent or per light?
So production in this experiment was 1gm per led watt?
The advertising I have seen claims that one of these led 300w units is suposed to be equivelant to, or better than a 600w MH/HPS?
Would you not therefore be expecting production to be up in the region of 600gms for this light? (at 1gm/watt)?
I have also heard repeated mention of the LED units running cooler, producing less heat inside the grow room, but no one seems to actualy specify by how much they run cooler?
If I were to swop a 600w HPS for a 300w LED, How much heat (on a comparative basis) would it produce, Half? Quarter? Eighth?
I already position the ballast outside the grow area, so please ignore the considerable heat that comes from that, purely the HPS lamp/holder assembly against the LED unit? Any of you Tech guys got any Ideas?
Thanks
