just finished my first go-around with my cabinet using autopots. I'm sold - my big issue is that I have to leave home, often 4-6 days at a time. I was away probably 30 days total out of my 90 day grow & they worked flawlessly and efficiently. I found that 3 plants (that each yielded between 1 & 2 oz) mid flower could go about 7 days on a 3 gallon resevoir in my set-up. I tried just using the smartvalves in my own trays so I could pack more plants into each chamber, but I started fighting algae & I never did get a great way of keeping the smartvalves from floating up. Seems like they designed them to be difficult to use without their own trays. I like 'em enough that I'll be buying a few more trays to fill out the cabinet.
I used 50/50 coco/perlite with about one inch of pure perlite on the bottom for drainage.

Ok what i know about the autopot
The smart valve the heart of the system
The smart valve is a very sentence device and should not be touched
the device works by trapping air into it and stopping the Nutrients like a float switch once the nutrients is used up the air is release and the trays will begin to refill again.
By lifting the pots and touching the smart valve u could be releasing the taped air in the device and f in the hole thing up.
Over watering
Over watering is caused by using the wrong amounts of media.
smaller pots up to 10'' or 5 Litre need well draining media 100% perlite work best.
larger pots like there 12'' pots need a media that can hold more water a 70% perlite and 30% vermiculite mix works well.
I must say that there powdered nutrient is the best nutrient for there system well it was design 4 it and its the cheapest 2 part nutrients u can get.I will put there nutrients two the test come winter.
