I sprout a mixture of barley, wheat, sunflower seeds and small red lentils, to try to maximize nutrition.
When using smaller and softer grains, like wheat, the key to sprouting is to not over soak the grains. Many sites say to soak them initially "overnight" or even for 24 hours. I have found that 6 hours is plenty for the initial soak. Then, I rinse the seeds once or twice a day, making sure they drain throughly. I put my trays at a slight slant to really make sure the water drains cleanly and fully. By Day 4, I have a nice, dense 1/2 inch of green sprouts, at which point I feed to to my rabbits and chickens.
When I was doing the overnight soak and not draining thoroughly, I really struggled with stinky seeds, poor sprouting, and mold problems. Since limiting the first soak and tilting the trays after watering, I haven't had any problems at all with mold.
