Here, I am going to highlight the nitty-gritty parts of the operation.
This is where it all starts.
For the resevoir exit, I drilled a hole in a rubbermaid and secured a small piece of tubing into it with some waterproof caulk. This small piece of tubing is then connected to the rest of the line by that funny white connecter doo-dad. Having a removable connection point makes cleaning very easy.
I find that I don’t necessarily need a check valve since the T-joint is significantly lower than the pump. I used to have one check valve for each line, but I found that the check valve restricted the one line quite a bit, so I removed it. After doing that, I found that the check valve line was much quieter. It seems that without the valve, I experience the gurgling noise. Hmmm
T-joint
A very simple setup here. The resevoir is about a foot above the T-joint. This creates more than enough pressure, even when the water level is quite low. After the T, the flexible tubing continues for about a foot and then connects to the rigid tubing. To make this connection, all I had to do was shove the flexible tubing into the rigid tubing. No leaks! Easy.
Here’s the top of the farm. I used zip ties to secure the rigid tubing to the chain. To get the coiled up, rigid tubing to straighten out, I boiled some water and syphoned it through the tubing. This allowed me to bend it and straighten it with ease.
I used to have some serious gurgling sounds. I found that by lowering the T-joint, I was able to get rid of them. No need for a silencer. The key is to make sure your tubing has lots of water running up it at one time.
One thing I really like about using these chains is that I can adjust the height of my pots at any time without disturbing the others.
Here is the bottom of one of the pots. You can see the net cups full of clay balls through the holes on the bottom. I thought I would have to plug up some of these holes so that water wouldnt be dripping everywhere, but (luckily) I was wrong! By hanging the pots on a slant (see gallery), the water only drips out of one of the holes! This is another nice feature of the chain. I can change the angle or direction of slope for any pot at any time. So, what did I do about the bottom pot?…
For the last pot in the line, I poked a hole in a plastic bag, taped a piece of rigid tubing to it, and shoved a piece of flexible tubing in it. The tube connects straight back to the top of the resevoir. The net cup sits in the plastic bag. This is a simple solution that works like a charm. You can also see that the pot is hung at an angle.
