I would give it a shot. Soak your seeds in
hot water. I start mine in 3/4" soil blocks and bottom
water with
hot water. A heat mat is very helpful. If you don't have one try starting your seeds on top of the refrigerator.
Even if you don't get a great harvest this year you can trim your pepper dig it up, pot it and bring it inside. Then next year you will be ahead of the game.
So sorry you had bad luck with Bakers Creek. I think you might want to contact them. I have always gotten exactly what I ordered in a timely fashion. They are my favorite. I could be wrong, but they seem like the kind of company that would want a chance to make you happy???
Good luck, I hope your peppers grow fast and produce well.
