Peat pots or peat pellets? The pellets take some getting used to, but again it's not given me problems.
The nylon netting ending up in the landfill is a more compelling argument against their use for me personally.
With that said, we're going to try an experiment this fall. We've got a bunch of empty toilet paper rolls that we're going to fill with our soil mix. A coffee filter at the bottom holds everything inside it. On transplant, cut the toilet paper tube out. - I've used the peat pellets for years but have had enough questions about them myself that I'm investigating newer possibly better methods.
