Eliminate the coils

Just an idea, but you can eliminate the coils indefinitely depending on the type of grow your doing - Using a blast chiller inserted into a 5 gallon bucket, you can use that for your feed line (note: this will cause condensation during lights on)

I know the heat given off from my transformers is going to be an issue in the type of rooms I'm going to be setting up, I can't post specs here because of everything else I've posted, but I've now got enough space to play with it

Another idea I had for your heat sink was to mount your transformers directly to an aluminum spreader and solder that into your frame. Although I feel this would adequately dissipate almost all the heat generated from those two transformers (or three, however it works out) this would be a marvelous application in what I'm building. Although unfortunately it would increase the cost exponentially.

anyway, if you could let me know the source of your circuit board and let me know if you just ordered a blank or had it manufactored that would be great. As I said, mine are $45 each for what I want so far, and thats not exactly cost effective for what I want to do.

(The idea is to create large quantity grow rooms for under 10k each including CO2, RDWC, lighting, and cooling in a sealed environment)
