OK, I am so disappointed, I have used this system for most of my seed starting since it came out (maybe 30 years ago?) I've needed to replace parts here and there but they seem to last forever. They were a 5 piece self watering system made out of rigid styrofoam. Recently, I wanted to order a few new parts and found that they don't make the system any longer. I'm sure that the self watering feature has saved my seedlings many times over the years. I'm just curious if anyone uses some other brand of self watering seed starting system?
