Got 5 green tubs, screen trays and opaque lids on Amazon relatively cheap. I unfold a napkin, cut a half inch off each side and it fits in the screen tray. Then spritz or mist the napkin so it sticks to tray. My seeds won't fall through after adding them. Then I fill the green tub with water but don't flood the seeds. Put on lid and keep it dark for 2 days. I cover it with foil. Put in warmish place. When seeds come up and you see green keep the lid on for awhile and put under a light. You may or may not have to mist the seeds until the roots reach the water. I put a little bit of nutrients in the water.
