My first post
I've been quieting tracking this grow (as well as botanist85's and some others) for some time, I just wanted to thank you Irish for putting all the time and effort into this grow as well as your past one (read every post) to help us all separate claims from reality.
Bring on the flower time!
I hope Mike's product(s) will deliver both for the community's sake and his own successes, I can only imagine all the trial and error it's taken him and all the led folks to try and get these lights and spectrum ratios dialed on target for our crop of choice.
Also just wanted to express thanks to Mike of GLH for keeping the claims within reason, and being very responsive to the questions that are put to him on threads in these forums. Under promising and over performing is way better then the reverse given the led market prior to 2010.
From what I have read I think LED and the new plasma lights (barely on the market yet in Europe I read somewhere, 6k a piece) may be the future of indoor grows, we're just not there yet. Hopefully this grow and the associate products will aid in the next evolutionary step, taking led's out of the tiny niche and toward a more mainstream future.
One question I do have that I've not seen specifically answered or asked about these brand of lights (or most other led's), is the BTU spec on them. This may be a case of me being an idiot but should I just assume a straight watt to btu conversion on the order of the spectra 600 putting out around ~2050btu's, about the same as 600w hps?
I keep seeing the talk about lower heat out put, but in theory at watt for watt that can't really be true can it? I get the directional heat benefits angle, ie can be closer to canopy, but from an overall room cooling\btu heat removal standpoint there is effectively no difference (at watt4watt anyway) correct?.
Thanks again to everyone for sharing there hard earned knowledge.
