Hi, Mary Sue, The seed incubator is a $35.00 item that you can get at OSH or many garden supply centers. It's just a low-power plastic heating pad, which keeps the seeds warm. Atop the pad is a pastic tray with a plastic insert with many wells for planting the seeds. A transparent plastic cover completes the "greenhouse". My great concern is that I've got these seeds germinating (well, some have, and I hope many more will) in a warm moist incubator. But, some are ready to be moved outside, where winter is just starting. I'm not sure of just how to go about acclimating them to the outdoors; I know they need real sunlight and daylength change which they won't get on the dining room table. David
