Yea, that's what I meant. Thanks guys. :weed:

I had a few questions if anybody knows. Should I ground the heat-sink? Can you connect drivers in parallel before the AC outlet (to cut down on # of cables)?

So I used both drivers, but ditched the 3-up chips. They would have fit (barely), but it would have been too much for the heat-sink thermally. The copper shims worked perfectly; luck was on my side as I did not have to flatten the tabs on the Ideal holder. The 18ga 8-conductor "alarm wire"...

It's constant current @ 700ma with variable voltage, giving up to 57v to use on each channel. I don't know if it's possible to bridge channels but I feel like it would be simpler to use a driver better suited to your application. You could potentially parallel 2 on a channel but that's going the...

I got them from here: http://www.ebay.com/itm/131592491554 The seller relists everytime they sell, so he might have a lot of them.

No no, I've heard of using urine. Isn't there a concern with the contaminants in the urine used? Your idea sounds interesting. What sort of community do you live in?

LOL - Things to file under "If things go post-apocalyptic". You can also concentrate your pee to make explosives.

I think it has a lot to do with soil biology. But these nutrient fixing processes take time. Perhaps by being able to manipulate things a bit, like adding a disproportionate amount of red wigglers and myco. The no-till style of growing seems very effective. Brownguy420 on youtube has good...

Does tinning the wire provide a more electrically sound connection, or is it just to keep things in place? I was planning on just putting a dab of thermally resistant glue on outside.

All good, I appreciate your input. I have 8 conductor "alarm" wire, which is solid, so it's an attractive option. I also have stranded though.

If Im doing 2 drivers it'll be a cob and a chip each channel. If im doing one driver, one cob and two chips, a channel.

Should I connect two channels at the end of the line like that? You're right about the epoxy, I can just hammer things off if I want to reuse the heatsink for another purpose.

I think I can use the Ideal holder with the shims. They're thin, and the Ideal holder should overhang it, and line up with a t-slot channel. It'll be floating between the cob and the t-slot, so I might use adhesive on one of the sides of the copper. I'm not that confident the heatsink will deal...

I wanted to avoid buying a drill press, and putting too much money into the build. I'll think about it for a day, though. It's a useful tool. Thanks for your help. I feel like I'm trying to fit too many cobs in such a small fixture. It IS concerning how close to the deep walls the LES are. I...

I received the CXA30 Ideal holders, but it seems like I'm transitioning to thermal adhesive. I have some textured aluminum that I was going to make a shroud with.
