Pete, maybe you can share your germination methods, and also what types of plant
seeds your trying to germinate. Maybe some of us can help refine that or figure out what might also be a problem and help to determine if indeed it is the seeds or not.
Luches. I usually do one or two different Heirlooms a year, just to see if maybe there's something I will like and do regularly. I tend to like my tomatoes done in the soil tho. More of a buffer, and less chance of bottom rot. I'm sure I'll do tomatoes in a Hydro system again, but definitely not in a NFT. Probably in a perilite tube.
