@ttystikk I have been doing my best to catch up on your thread in what little spare time I have, but I have finaly gotten caught up from pg 129, which is when u had the cob's installed right? I remember you saying everything before that was a waste of time, lol.
Great work by the way, I am very intrigued by everything you are doing, I must say you are truly one of a kind! I was especially entertained when you posted the picture with the old lady (standing on a stool no less) in there for comparison's sake to show the scale of it all. Those are some massive plants, you got there. (wait, no those aren't plants, those are trees) how long do you veg those to get that big, and under what kind of luminaire? I seem to remember something about a 6 month veg, but Im pretty sure that was just that one plant, not normal operation, but I wouldn't be surprised, lol.
I am left with more questions than answers however, but i'll start with the water cooling system, since that's what I was originally asking you about.
As I understand it you are using a hollow rectuangular aluminum extrusion 1/16" thick, and something like 1"x2" (i forget the exact dimensions you said) and in maybe 2 or 3 foot sections, with cobs mounted them, and insulation around the rest, with chilled water running through them.
How are the cob's mounted to the thin aluminum. You obviously can't use screws on holders, or thru the chip, but then again, you are using lenses, so they are probably holding the cobs down. are you using holders, or are they soldered? How, and what are the lenses mounted to exactly? I can't imagine trying mount something solid, that can handle heat (eg. no structural solder joints), with nothing to screw into. how is your super waterproof (I assume) connection between the hosing that feeds these units and the units themselves, constructed? were you able to use some super cool adapter or did you have something custom made, and if so, how is it put together?
I could go on and on, but lets start with this. I would love to chat with you on skype or something sometime, I have a lot of questions, and ideas I would love to discuss with you! and You of all people know how long my posts can get more often than not, haha
Keep up the good work, and take care brother!
