Tonight, I had a minor catastrophe happen. One of the spots (where a tomato plant is going to grow) was not sending out water. The sponge was wet, but there was only a slight drip every now and then, and not the steady stream that is usually there. I tried to clean it with a Q-tip, but that didn’t work. So, I moved on to the screwdriver.
On the bottom of the Aerogrow, there are a bunch of little screws. I expected a network of tubes to be running through here, but surprisingly, when I did surgery on my machine, I found out there wasn’t. The top and bottom piece are made from molded plastic, and form a wide open area where water can run through. Each spot for a plant has a ridge where that water gets in, travels around the plant in a trough, and then out through the hole. Honestly, when you look at the bottom of your machine, it’s exactly like that, but about 1/8th of an inch deep.
There was a little gunk on there, probably from hard water. Not too much, but I wouldn’t want to eat supper off of it or anything. ;) I cleaned this up, and used a Q-tip in the trough area, right before the water goes through the hole and into the plant.  After cleaning it, I put it back together and put it in. This was a false start because I forgot to screw everything back in place, so I took it out and put the screws in this time. But because it was so late at night and I wasn’t thinking clearly enough to realize that I forgot the screws, I figured out what happened. I think, anyway.
When the screws were out, it was leaking water from all the screw holes, and the normal holes in the middle spots. But it didn’t have enough pressure to get to either of the end spots. What I think happened was that with all the cleaning and scrubbing, a screw on one side came a little loose. And water being water, it took the path of least resistance and never got to that hole sufficiently enough to come out. After tightening the screws, it seemed to help. Now, even though I don’t think the gunk was a problem, cleaning it certainly didn’t hurt.
So there you go. If you’ve got water coming out properly on all the holes except one, I’ll bet it’s an end one. And if it is, try tightening the screw before you take everything apart. I bet that will fix it.
Finally, and just so you can amuse yourself at my expense, I scrambled to figure out why it wasn’t working, and just grabbed the pods and set them to the side. When it came time to put them back in, it took me a minute to figure out which was which.
