Now I am in no way questioning your ability to grow whatsoever, nor your credibility on this forum. But honestly, do you know how many requests I get like yours? Literally every week I have a new grower, who has a following going on some forum, asking me for free units, offering to do a demonstration, and saying they'll sell lots of lights for me. To date, I've given out exactly 0 free units to those who've requested. The only free unit (other than what Ed Rosenthal received) that's being sent, is going to Setting Sun on this forum for a comparison grow against the Haight PPF-800, 190W LED grow light. I did so at the request of the moderators here, and after the test is complete he has the option to get the unit or return it.
So you have a 3' x 5' spare room, but what would your canopy space be? With LED, I only supply enough light for the canopy area, so it would be good to know. Also, are you aeroponic, hydroponic, or dirt? I prefer aero. What brand of nutrients do you have for options? I prefer Advanced, but there are a lot of good brands out there. I may be willing to work out some sort of deal for you to post a journal online, but I won't be offering you free units.
