So I am having difficulty sprouting my chili seeds using the ENO method (wet cloth) because I believe the temperature at my place fluctuates too much between 16°C during the day when I'm working and 21°C when I'm home.
Now I was wondering what temperature the radiator gets when it is on and if it would - for example - be better idea to plant the seeds in soil, cover the container with foil and put those directly on the radiator to get the ground to warm up? Since I believe the ground will stay warm longer during the day and night when the radiator is off. And it won't get the direct heat from the radiator itself so it won't "cook" the seeds being on there directly.
What are your thoughts?
