    El Cheapo water chiller.

    I picked up a functional mini fridge off craigslist that isn't very old maybe a year or two for $50. I'm going to cut and solder a 1/2" copper tubing manifold inside, then drill holes in the side of the fridge to bring water in and out. I'll install the fridge outside the grow room so it...

    Potassium Peroxymonosulfate

    Anyone running sterile use potassium peroxymonosulfate? In a nutshell it breaks down inorganic compounds to free up chlorine, so you can run a lower concentration with a higher ORP value. Picked up a bag from the pool supply store, its 1# for 5,000 gallons of water so basically a lifetime...

    Bigger = better for drivers?

    http://www.trcelectronics.com/View/Mean-Well/HLG-150H-48.shtml Looking at this. 3.2 amp output. Could be used to run 5 2520's or 3 3070's with ease. At $65 a pop it would replace 5x $20ish each for the 2520's plus save a boatload of wiring and mounting. Any reason not to wire in parallel...

    UV hydro sterilization

    Anyone use UV to keep their reservoir sterile? Wondering if it will break down media, or if you can run it every time you top off. Would eliminate scrub and steri with chemicals. http://pentairaes.com/greenfree-uv1.html 5.5 GPM so has to match pump size and flow rate to work effectively.
