Greetings- We've tried seeds from various dehydrated chilis with mixed success; it probably depends on the heat level of the particular dehydrator. I managed to sprout some seed from a year-old ristra once. But for our own seed we let the fruit ripen on the plant; when harvested I slice off the sides of the pod & air-dry the 'remains' on newspaper indoors for 2 weeks, then pull the seeds off the dried placenta, seal in plastic bags, & freeze. In general I'd say that a dehydrator is likely to be too warm [at least in spots] for the seeds. We have an inexpensive greenhouse to get us through the colder months; it isn't always needed herein n-c Florida. Ours has steel arches covered with heavy-duty polyethylene that is treated to make it ultraviolet- resistant. Make sure of this feature, or use vinyl---regular polyeth ["Vis- queen"] breaks down in sunlight! The other caution is to anchor any greenhouse to the ground---we returned from an out-of-town trip to find the greenhouse apparently missing & finally discovered it partially dismantled behind the barn where a high wind had deposited it.
