heya Stank,
I did make a thread about an auto water system, seems as though the blumat's are highly recommended. If I go much further with auto wateres that is the route I will go. This is not a drip system, just a way to easily get fresh, airated water to the pots. More or less turn a small valve to turn the water on / off. It could be used as a drip system but I prefer wet / day cycles. I've never done a drip type grow.
Due to time restrictions I found some aquarium hose / splitters / adjustable valves at Walmart. All on sale 2$ a kit, bought 3 kits. I used the adjustable valves as the emitters (unscrewed the adjuster, so its more like a T fitting. A few inches of water line, another emitter, each pot has 3 emitters, run around the outside of the pot, attatched with Christmas light eavstrough hangers.
I have a 1/2" water line running into the tent from an elevated Res. Once inside the tent it goes to a 4way splitter (only 2 are being used for the 2 plants) so 1/2 inch going in, and 4 - 1/4" air line hoses going out. From there it connects to each pot individually, to another other adjustable valve, this one is the on/off switch and adjustable flow rate.
It is connected to a pump but I only use it to prime the system, I prefer to keep it gravity fed. It is not currently on a timer, more or less it is setup so you turn a valve at the pot and it drips water. You can then hang out until u see runoff and close the valve.
Ill take a few pics for you, I'm quite proud of my little setup. Just wish I could of had it fully automated
