All sprouts need warmth. It will not sprout in the refrigerator. I have not yet sprouted almonds, but I know that harder the seed the longer you need to soak and also need to rinse more times as well. My moong sprouts take one day, wheat grain takes two days. I will try almonds tonight and let you know. I just take a thin wet cloth and put them away in the dark warm place inside my oven, not heated though.
My next post will have pictures of my wheat and moong sprouts.
