To safely grow sprouts, you will need a large glass jar, a sprouting lid, a holder for your jar and a tray to catch excess water. You can make your own make-shift sprouting jar using a cheesecloth and rubber band instead of a sprouting lid and create some construction that supports your jar upside down in order for excess water to drain. This may be more cost effective but especially as a beginner it is advisable to get the right equipment. This way you will grow sprouts successfully and safely.
