Easy Sprout Sprouter

How do i prevent my broccoli seeds from growing mold? i've tried citric acid, dark closet, rinsing throughout the day, etc. details please. thx

Dishwasher safe?

I'm having trouble knowing how to use this as the directions are not very clear. I'm trying to sprout fenugreek seeds. Where do the seeds go?

Is this made of plastic? BPA free?
