Greensprouting potatoes – getting some well developed sprouts before planting seed potatoes in the ground – can lead to earlier and greater yields, or enable you to grow longer-season varieties. To greensprout, keep seed potatoes at 70 to 75 F in the dark for a week to break dormancy, and then keep them around 50 F and provide at least 12 hours of light for a few weeks so that sprouts emerge but stay short (about 3/4 inch).
