Ok. I am once again getting ready to order my seeds and I will be starting some indoors. (Mostly annuals for my containers, and some perennials as well) I have tried for 2 years to obtain some PRO-MIX. As I have read it is the BEST for seed starting... but I can NOT find it locally in the southwest metro of Minneapolis, and I refuse to pay $70 online for shipping! I have read some other posts who say Jiffy pots are also very good. And I can get them CHEAP, AND I am rather intrigued at the NO MESS possibility- no filling cells!!! So I wanted to know if any of you guys have tried them and the pro's and con's you have encountered.
