First, I have no interest in either of the following mentioned companies other than that I’m a satisfied user. I recently got a bigger greenhouse  for my birthday and have used it for this years garden plants. A little over 200 plants so far. They have two models on sale right now. I do recommend completely caulking every panel with adhesive caulk. The large one took 30 tubes.
I have ordered this stove  to heat my greenhouse in cool weather and through the winter. I keep two tons of coal for the house coal stove anyway.
This combo will be much better than my old greenhouse system. With them, it is cheaper to heat and I have more available space. With a lot of stored heirloom seed and canning from three gardens we will have plenty of food. – D.M.
JWR Replies: Those are both good suggestions. I can vouch for Northern Tool & Equipmen t  as a reputable dealer, (as I’ve done business with them for many years and they are one of our affiliate advertisers ), but be forewarned that a fair portion of their merchandise is made in mainland China.
Because both stoves and greenhouse have high shipping weights, I recommend that readers shop around and try to find a good price in their local area before resorting to mail order. My favorite mail order stove dealer is Lehman’s , headquartered in Kidron, Ohio. They have a fascinating line of traditional non-electric merchandise, originally developed to service a primarily Old Order Amish clientele.
