Great show Craven--congrats
My neighbor has about 350 twin AutoPot units in his veggie/fruit greenhouse. I've noticed the smart valves don't open until the water level is barely visible--say 5 mm--in the valve container. Then the valve shuts off when the level is about 65mm. This allows the coco to almost completely dry out before the valve opens and the water/nute cycle begins again. No spacers or wicks are being used.
The pots are 10 liter (2.5 gal) and the coco is pretty much saturated after each cycle (the mix has ~15% perlite evenly distributed). The valves haven't been modified and appear to be functioning perfectly though not exactly in the way you describe they're supposed to.
He's offered me 50 units for my use. Do you think his valves are malfunctioning or ??? And what are your thoughts on this? Thanks amigo
Must feel nice 2 have her dialed in bro : P
What's the E.C. of yr tap water?
Craven_au, That CoCo your useing looks like it's ground up real fine, I wonder if a corse CoCo would work beter and won't hold as much water? Great thread dude.
