Please do! Thanks for the kind words. This is the old "blackout series" UC4XL13 without some of the recent enhancements like easier-to-clean joints. I did adapt the epicenter with a new float valve from the new series. My setup looks exactly like the one below, except with a chiller on the return pump.
I can't lie, it was an impulse purchase. But what can I say? It just works. It's incredible. You calibrate it once a month just like you do with their other meters/controllers, set an on time/off time as well as a timeout in-between doses. Uses far less pH adjuster and stabilizes pH even as new RO flows into the res. It significantly minimizes the time I would spend pHing nutrient solution.I hear from a few others that bluelab controller is the business. Any thoughts on it you'd care to share?
I don't have a cadence down yet, but my "weekly" plan is to set the pH controller to 6.5 as RO comes in, mix in nutes and let them bubble, set the controller to 5.8, let it bubble, and then change the solution.
But as far as the controller goes... if you've got your source water figured out and you're a pH master, it's less necessary than it would be otherwise. I have it connected to my res which can have a varied amount of water in it at any given time, so it's beneficial to me. Definitely worth it regardless though if you've got the cash. The more time spent training the girls the better!
