OK,last post,I dont want to hog the thread...
Agree,coffee filters,paper towel and paper napkins also work well.Ive used those plastic clamshell trays with 'blotter',works well for the alfalfa and broccoli and radish types very well.Then I put clamshell in a tray to keep bottom moist with frequent water changes (2-3 times a day) after day 4,until then I only spray misted with water.And its cheap,only need to buy seeds.
On day 7... I removed the blotter,rinsed under running water to remove unsprouted seeds and back into clamshell without blotter,Day ten was amazing.Included is a lovely mung bean/alfalfa/avocado salad,also you can make an antipasto style with meat,but not included to not ruin it for the veggie folks here,but it makes a great salad!
