Yep! I put the float switch to a relay, so it switches the pump automatically. When the pots dry out, it wicks the runoff and activates the switch. I put a half inch of perlite in the bottom of my pots and I try to get the liquid level at somewhere in the perlite.
The main advantages are that you get the wet dry cycle, but also your pots never go fully dry. The plants determine their schedule. Also it’s a top feed system, which I think is generally superior.
To run a flush, you just drain the bottom liquid, and then it’ll trigger it to drip to runoff.
I tend to add a little more perlite for more aeration and faster cycles. I’ve been running it full time for about a year and a half now, and now I’m getting my 4x4 tent converted over. It’s a great system that’s almost too easy to use.
I had a thread going on it over here
