Could you get another auto feeder and set it to dump right amount? You would have to fiddle with it and try it for a few days before you put it over the tank.
Just want to be sure, dry or liquid fert?I can't afford liquidosers at this point in time. Thoughts?
Been there, done that, never again.Check this out at DrsFosterSmith.com, it's an auto feeder that would be perfect for auto (dry) dosing.
It Has a nice capacity (check out the size of the bins next to the electrical plug) and would be precise, you fill each bin with whatever amount you want, with 28 cells you are covered for almost a month! or you could make it work double duty and alternate between ferts in one cell and food in the next and set it to dispense twice a day (first ferts, then food each day) That would cover you for ferts and feeding for 2 weeks at a time.
I have actually been looking at this myself, but fo me it is more that I'm lazy than not home, so it's hard to justify...
