No reason ground loops wouldn't work, the only issue I see is upfront cost of getting the loops below the frost line. Some areas of Colorado are pretty rocky and it would be a big PITA. Also have to insulate where it enters the structure or drill through the foundation beneath frost line, not terribly difficult but depending upon where you live could be necessary. After subtracting the pump draw from the chiller draw and adding in the labor needed I'm not sure it would be worth the effort from a cost standpoint. As an off-the-grid application where you are dependent upon solar this could be a great solution, however.@PurpleBuz @BOBBY_G do you guys like his design with the copper pipe, or do you think a water block would be better.
I am imagining and brainstorming some designs for my new garden on my property. I feel like chillers that use 350-700 watts is counter productive to the LED philosophy. But what about earth loops? What do you guys think about using copper only to interface with the heatsinks, then coupling into PEX line which is dirt ass cheap, then running a pig tail loop through the earth to remove the heat.
-this is the concept behind geothermal HVAC units.
@DISTRESS0R well, I like to keep an open mind about new products. Lumileds are not really impressive on paper, especially when some cxb3590 users are getting 2.6-2.7 µmol/J .
If all of these smaller diodes are inferior to the COBs we love and use, why are most of the manufacturers moving to these small diode package light engines.
Examples:
-Spectrum King : closet case & mother's little helper, possibly their new SK600+
-Fluence Bioengineering's : Razr, Vypr, SpydrX
-NextLight
Is this just a cost of manufacturing choice?

And man o man do I love this guys grow room! That 8' sink is freakin awesome (THAT wasn't cheap!) the entire room is so well thought out. Lot of light spill due to the table spacing/walkways but pure efficiency doesn't appear to be a priority for the room, more about convenience and easy access. Nice!
