Very true, and that's what I do now with a 400W HPS during the cooler months. As things stand I use my house to store cool air collected at night and push hot air through my attic to the outside. My basement stays cool all year round and this seems like the most efficient way to exploit the...

I hadn't thought of epoxy... It appears that standard CPU heat block size is 50mmx50mm, so the cob would fit, but not the holder.

How do you cool the lights with 80-100F air? I can't really duct air from the basement. 1000cfm of 90F air can't really help me. Active heat sinks have all of the drawbacks of liquid cooling, only less efficiently. I can cool the space with two heat exchangers, fans and heat sinks but air is...

I live in an area where it is in the 80's (F) for most of the summer with a few 100+ days. Currently I have 200w T5 grow area (about 2x4 feet) and a 400w HPS in about 2.5x4 feet. I don't grow commercially and I pay for my electricity. I have a background in I.T., construction and DIY/Maker type...

I feel like an idiot. 80/20 has a 20mm series. Here is a bracket for attaching a wire panel that should work perfectly to attach one side of the heat sink to an 80/20 profile with two 10-24 machine screws and two 3mm machine screws. https://8020.net/shop/20-2493.html Bosch and many other...
