I have a friend with a professional metal shop I could get to lap my down. The cpu heat sinks are probably done pretty well, but the stuff from heat sink USA I doubt is

They're old seeds so I'll give them a little longer. It's been 2 weeks now I guess I'm also wondering if the glass container is building up too much heat

Older seeds. Soaked in water maybe 24 hours. Then into damp paper towels inside a glass container with lid. It's on a heating pad set to 78 None have so much as cracked

None of the seeds germinated on the heat mat. Not sure how long to wait at this point

You dug up a long dead post. 2011. For diy look at stinkbuddies

Thanks supra. I'd been worried I was giving bad numbers. @J It would give you a lot of expandability with a fancy fancy touch display ;) If the three pin / 4 pin thing I posted above is right then this should fit...

Want to get fancy? https://store.nzxt.com/products/sentry-3-touchscreen-fan-controller A post about 4 pin fans on 3 pin controllers. My alpine 11 plus fan is just wired to a phone charger wall wort. I'll have to look at my unused one to see how many ports it has. Another way would be an...

I would not hook up the fans to an led drive if that's what you mean. I'll see if I can find what I'm thinking of

I'm looking at running multiple narrow profiles so I can mix and match for different spaces I'm sure it looks nice though

Damn. Why go with one extremely long one instead of smaller ones? My plan is modules to adapt to different size grows as I move around

Width is 12.000" Fin Height is 1" Base Height is .300" Weight is approximately .60 lbs per inch C/W/3": approximately .85 (12 x 2) + (0.3 x 2) + (31 x 2 x 1) (24) + (0.6) + (62) 86.6 perimeter 86.6 x 6.45 = 558.57 cm2 Price $5 558.57 / 5 = 111.714 cm/$ Really wish I could get confirmation on...

Thanks, glad you came by. I took an electronics course back in high school but I never heard of constant current drivers until the last few years. And truthfully I never looked into then past their given specs. Maybe it's not. But there's a reason I never made an led light until these cobs...

I just saw they were constant current, or thought I did. That was what I searched for anyway

@SupraSPL Did I do the above numbers right? How about these? Extruded Aluminum Heatsink Width: 1.813" Fin Height: .95" Base: .300" C/W/3": approximately 4.5 Weight per Inch: .10 (1.813 x 2) + (0.300 x 2) + (0.95 x 2 x 6) (3.626) + (0.6) + (11.4) 15.626 perimeter 15.626 x 6.4499618029 100.8...

It gets to looking complicated to do it right http://m.machinedesign.com/archive/circuit-ideas-how-parallel-led-current-drivers

Yeah I'm sure it's a fine line of diluted enough to not hurt plant tissue but strong enough to kill pathogens. I need to get some stuff to try myc. I spent two weeks going to a psychiatrist for ketamine treatment, way too expensive. Want to see if mushrooms well help with micro dosing.

Isn't diluted bleach economical? My understanding is that college labs teaching tc use flowers and use diluted bleach as well

I look forward to your experience. Wish I could get into it right now myself. Did those sources I sent do you any good?

Heh, search two drivers one cob. That's supra's humor for you.

Instead of going with one of the high end drivers with dimming , I'm going to try supra's 3 way switch type thing. I won't have any middle ground if I use identical drivers, but he used two drivers at different amperage and had 3 known amounts; A, B, A+B. I probably lose efficiency that way but...
