Just a small update on how things are holding up:

They're holding up great! The pump kicks in about every 2-3 hours and runs for about 5 seconds Doesn't take much to cool it back down. In the distant future I could add some leds to this. I wonder if soldering the pipes with the leds still attached is totally out of the question or just a very bad idea... hm...

Still no new cab, though. The plants are actually doing pretty good for now, and I am thinking a very tight scrog could work...?
