Ya, I had a tool sorta thought up when I talked to you about the Rawson. Then when the boss and I got to discussing it, we kept coming up with the time it would take to rework somethng vs. just starting from scratch. I think he learned a lesson on a few items in the past that took more time to change something than to get started right off with the build. Lots of things work for adding to or substituting for, but sometimes the basic framework has to just start anew. I prefer liquid nutrient, but at the time the boss was hot on the dry, hence the interest in the fert setup you had. Once I started in on the clean up and the moving parts, he was quick to come round.
