I'm one of those people that says, "hey, even though i'm not gonna use LEDs, i think its awesome that you do. tell me whats good and bad about it".
and on the grow journal thing, i know this is all confidential and all, but i had an encounter with a non-marijuana issue. i learned the hard way that everything you do and post on the internet stays on the internet somewhere, no matter what you do. i just don't feel completely comfortable posting pictures that could eventually be traced back to me. one day i will, but it won't be for a while...
and if thats not convincing enough for ya, then i don't know what will.
