Well, I finally tinkered with the sensor/float long enough that I think I solved the non-draining problem. The controller has two floats towards the bottom. The one towards the front of the controller is supposed to be at an angle, the other one which is slightly higher needs to be perfectly straight. Both CAP and my local hydro shop helped me out big time. I finally just got a level and made sure everything was perfectly level and straightened out the float. Drained as it was supposed to. Don't think the issue will come up again, even if it goes crooked again, as I purchased an a/c unit to control my heat problem and have it sitting on top of my controller. The minor vibration of the a/c unit should be enough to vibrate the sensor if need be.
With the heat and drain problems fixed, my plants are starting to love this system. Amazingly quick growth in just two days of running the system properly, although a bit fat and stubby (might be the BBC strain, idk). I'm running Lucas Formula (just FLB), so I'll probably be topping off the rez with a bit extra N (probably FLM). Sigh....although everything is running fine now, I hate the stress of things going wrong. Had my dog not massacred my younglings, I would've had the time to fully setup and test the system BEFORE transplanting. Always something.
