Hi @Klimbim, yes the UTM is a great design, but poorly executed. Connecting wires to screws with a cable tie is a joke, I used solder eyelets, so soldered the wire onto the tag and then attached the eyelet to the screw with two nuts.
But I’m not using my UTM much and considering removing it completely. I have the water tube plumbed into a dedicated watering head (shower head) attached to one side of the UTM. I plan to do the same with the seeder, that way the dodgy tube connections can be avoided. The seeder has the metal needle hanging down, so I’d just remove that when not seeding, and otherwise leave the needle holder in place attached to one side. At the moment I don’t see the need for any other tools (for my purposes, which is just growing vegetables!).
I might add another watering tube and attach a misting head to it, for watering delicate seedlings, I find the drenching from the shower head is pretty hard on some plants.
