i would focus on aqua valve and air dome mate!.
Maybe I'm missing something here, but what's so great about these systems? I looked at the site and it basically just looks like a bigger more expensive version of a self-watering pot like you could get at any home improvement or gardening store. I guess I can see that they offer the ability to water less often with these and perhaps less risk of over or underwatering. What's the other purported benefits of auto-pots? Bigger yields, faster growth or quality?
