This year I bought some Jiffy Peat Pellets and some Coconut Fiber Pellets. The coconut fiber pellets work just as well as the Jiffy peat pellets however the sprouting time is a little longer. They do however seem to hold moisture better. When first starting they take longer to expand fully, but not a big deal for me. Overall I think these coconut fiber pellets work great for my needs, and I will be using them again next season.
