I’m sure I have something to trade for the Cosmonaut Volkov… What are you looking for? I have all sizes, seasons, mostly heirlooms and many Russian and Ukrainian tomatos. I have my own Strains I am working on developing also, but they are not stable yet, so they would be considered experimentals. I am on the F4 generation for those. I have non-tomato seeds in limited supply as well, and tons of dill, mustard and kale seed. Let me know what types of seeds you are interested in.
