You kown this could still work - I just like this idea - I think if we just did a bit of a on-line seach then we would know what zone our seeds would work for and label so people would know how to plant their seeds
for exp - I'm zone Zone: 7B
good site for that info http://www.garden.org/zipzone/index.php
so if I get seeds that are only good to zone 9 insead of planting outside I could just grow them in a pot. Or if the seeds just won't work we may need to buy seeds that would work in the zone of our swap person. seeds are cheap - the main thing would be the packet that you would be sending them in.
What ya think?
