They'll germinate cool (60-70 degrees F), but if you put them in a warm spot (75-80 degrees F), they will pop up in just a couple of days. But if you are germinating them warm & quickly, keep a close eye on them and get them to a cooler place as soon as you see the first sign of germination. If you keep them in the warm spot, they will get too tall too quickly and be "leggy," with long thin stems.

Good luck!
