So you've rounded up your rich soil and organic seeds, but things start getting tricky when you look at those darned sprouting trays!

How to Grow Microgreens

Microgreens are the superfood seedlings of herbs, vegetables, beans, and seeds. They're crazy health-boosters packed with 4-6 times the vitamins and phytonutrients found in the same plants when they're mature. Not only that, but they're very inexpensive and simple to grow all year around.

We've been homesteading for several years now and love our chickens, bees, herb and veggie gardens, but growing microgreens is actually new territory for us. So we think it's best to send you over to some of our favorite resources who have it all covered:

How to Grow Microgreens Indoors without Toxic PlasticHow to Avoid Toxic Plastic in Your Indoor Garden

The problem with growing microgreens is that most seedling cells/inserts, small flexible pots, and trays are made from polystyrene plastic (you know, the same #6 stuff used in disposable utensils and some straws), which should always be avoided.

A reader of ours confirmed that a basic stainless steel tray like this one works wonders for growing microgreens, and you can even grow in an oblong glass baking dish too for that matter.

And don't forget to give paper egg cartons a try! They just happen to be a perfectly sized non-toxic, biodegradable seedling starter. Then if you decide to move your indoor garden outside during growing season, you can plant them right in your garden without having to transfer the sprouts.

NOTE: Don't forget to stay away from foam or hard plastic egg cartons though because they're usually made from polystyrene (#6 plastic) too.

Just so you know, it's not really necessary to get all fancy and buy something new. We often re-use milk jugs, juice bottles and all sorts of containers made from safer plastic. The best options are made from polyethylene, LDPE, HDPE and polypropylene and should be marked with #2, #4 and #5 recycling codes.

We've rounded up plenty of great possibilities in case you'd rather go for the perfect size and shape for a countertop.
