Variety: All Purple. To cure I managed to build a heat incubator. I made it as an expanded polystyrene box, I put electric heat tape inside to maintain temperature. Washed, wet tubers have been packed into plastic bags with a few small holes, then put to plastic fruit crates. All of that is placed inside expanded polystyrene, hermetic (almost hermetic) box together with electric heat tape + thermo regulator to maintain the temperature inside. Polystyrene box is a very good isolator, so it's easy to maintain the required temperature inside.
I also have some temperature sensors. The first one, directly inside the box, is connected to temperature regulator and it's set to +32 °C (89 °F). Sensor inside plastic bags, with tubers inside shows 30-31 °C (86-88 °F) and humidity 90-95% so, the conditions look fine.
However, after 2 days tubers started sprouting, and some new, thin, white roots appeared on them, while the cure process is definitely not finished yet.
Does this sound ok? Have you experienced similar issues with sprouting? Is that really a problem? Am I doing anything wrong? How long should I wait to be sure they are cured correctly? And how do I know it's enough for them.
I guess sprout is not my only problem, I have no idea what's that on them:
It does not look like mold, but not looking good. Only some of them were affected.
