@bad karma: great, +k to you. I heard some horror stories about the panels, chips mounted on single thin plate of al and such. I respect your advice and will heed it.
I was thinking about these bastards: put "50w warm white led chip" into ebay search. The w/$ are simply absurd. With some reds and blues added, hell, what could go wrong?... I know. A lot. But still, the w/$... Also it seems that the drivers sold for those run them almost at max wattage. Which is a lot of wattage of leds. Opinions?
I will read out the shit of led threads first to see if anyone else tried. I have found an interesting one, but the results were not clear due (prolly) to growing mistakes. Than I guess it is my turn to make some educational mistakes.
I grow indoor for a short time. After a few moldy harvests, I decided to go autoflower in this cold unfriendly region we have, will try to harvest under the summer sun. So I decided to try my hand at a little breeding. Not gonna buy seeds year after year after what I heard about professional breeding practices. Currently, I am running a single 100w cfl in a small closet and it is kinda sufficient. I plan to grow heavily dwarfed plants in party cups and select for early seedling vigor, bud appearance, smell and potency, then go out in spring and do full scale evaluation - growth habit, resistences, yield...
So I can afford to experiment. It is a hobby for me, I can shell out some money, I do not need raw power, mostly I would like something that just works well, more equal light coverage, less overall heat, good handling, lower electricity bills, you know.
I know it sounds too good to be true and it will not be really true in its full extent. I expect complications. But how much true does it have to be to be worth it at that price?
I really appreciate advices. I am still learning about everything, your wisdom will not be wasted, I will take it into account, I promise.
Edit: btw, is there an smartphone app that would take a photo of white paper under a light and tell you the color spectrum in full par range? It should be possible, right?
