I remember the days of the ice bottle shuffle. That really blew chunks. But it was a step up from the "soil shuffle", potting and re-potting and mixing and the mess. I saw a thread that involved using coolers for rez's, which still require doing the iced bottle thing in most cases. About 6 years ago an idea struck me, and it led to the current setup I use now. Now my rez temps never vary from the temperature I set by more than a degree or so. None of you guys are running a scavenged mini fridge as a chiller yet? Oh, hey BTW Hi, This is my first post on this forum, nice to meet you all.
