Are you at the farm with the same Av?
How is the actinic plant doing ?
The farm is THCFarmer there is a guy over there that has the same pix as you.
I have been wanting to run an undercurrent system and have most of what I need to build one already. The only thing that has dissuaded me is the need for a chiller. If I plumb the pump as an external one like you did instead of submersed, would I be able to get away with it without a chiller?
Do you have a link?... no, I'm not active on the farm.
The same pix as me eh? ... are you talking about the grow or the funny pix at the bottom of a post? because I seal those from the net.

I guess I'm wondering if you or anyone else has done so. I figure a significant amount of heat can be kept out of the water by using an external pump. I just didn't want to go through an entire build and figure out after the fact that I need to now buy a chiller.If you can keep the water below 72*F without a chiller than I would say go for it!
