FWIW I save my plant trays, the ones with the "Grates" on the bottom. Place my tomatoes in a single layer. Place in cellar. Check for rotting ones 2x weekly Comments on other methods. 1. Ripening on window sill seems to make them mushy real quick 2. Adding banana or apple did not appear to speed up process but attracted a lot of fruit flies. 3. Bringing plants in also appear not to speed up ripening either. Did bring in a lot of aphids that got onto other plants. Byron
