So it seems that 6 sweet potato plants, in a 100-gallon grow bag (48" diameter x 12" tall) was a pretty good ratio. I haven't weighed the exact amount I pulled out of the dirt, this past weekend, but it was enough sweet potatoes, to pretty much fill a box, 15" wide x 18" long x 12" tall. Okay, so now that I've successfully grown the darn things, I have to find a way to "cure" them! Curing sweet potatoes turns the carbohydrates into sugars, and helps seal up any imperfections/cuts in them, and should be done in an area with 80 to 90 degree F heat, and 80 to 90 percent humidity. A cured sweet potato is typically good for ~4 to 6 months, stored at ~50 degrees Fahrenheit. So how am I going to accomplish this? Luckily, I had purchased a small pop-up "greenhouse", a couple years ago, that seemed custom made for this purpose. So I set it up in my storage area inside the house, lined the bottom with a couple of cheap terrycloth towels, and set up a small ceramic heater, and a jar with water. I suspended a hand towel from the top of the enclosure, with the end in the jar, so it would wick the water up, where the hot air blowing from the heater will blow across it, increasing the humidity inside the tent. Added a combination thermometer/hygrometer, and put the harvested sweet potatoes inside, after giving them a brush with a soft bristle brush, to remove most of the dirt. It's been 3 days now, and everything seems to be working perfectly! Knock on wood, to keep from jinxing it, of course!! The heater thermostat is set to maintain the temperature, and the humidity is sitting right where I needed it. Figured I'd share the idea here, in case anyone else has considered growing some sweets. Everything I've read, about curing them, says to keep them this way for 5-6 days, so I figure come Friday morning, I'll kill the power to the heater, and allow the tent to cool back down to room temperature. Then comes the challenge, on how to store them in the best temperature, so they'll last long enough for me to eat them all!
