I save a lot of seeds from bought vegetables etc. I have frequently grown peppers like that, but I save the seeds, let them dry out in a saucer then store them in a packet. I have not tried freezing them, but they should be all right in theory. Try it and see, you haven't lost anything if it doesn't work, but could get something for nothing!! I have in the greenhouse at the moment some melons growing in pots - initially I planted them in some compost and put a poly bag over the pot, holding it in place with a rubber band, and put them on the kitchen windowsill. When they germanated I took the poly bag off and left them a couple of days, then they were moved to the greenhouse and a couple of days later transplanted them into a pot each - so far, so good. I have grown apple trees, oak trees, lemons and pomegranites. I have a couple of palm trees just sprouting and have even grown a date stone - it took about eighteen months to germinate, but it is growing. I like experimenting, and as I say, if it doesn't work, you haven't lost anything. Can produce piccys of the plants, if you like. Go for it..............
