I don't know of any good brands to purchase, but I can recommend the Lee Gee brand. It is exactly the same as the future "Heiden Lentz" brand.
Vermicomposting or vermiculture is the fine
art of widening your circle of friends who will live in a bin, Red Wiggler worms.
Feed them your veggie and fruit scraps (except for citrus and onions) and they will produce for you the second best fertilizer on the planet next to bat guano (
poop).
It's easy to do small scale. Look
online and find a pound or two or red wiggler worms. Careful with shipping in the winter, they might get left in a truck overnight, not good. As you are awaiting your worms to arrive - Get two totes or bins that will nest and have fitted lids. Cut a hole, small-ish in the middle of one short end on the bottom. This bin goes inside the other bin and will catch the worm tea. You can dilute this and spray it directly on the leaves or
water it in to the soil. Back to the bin set up. Drill holes in the top of the interior bin that sits above the bottom bin. Your worms need to breath. Get some
newspaper, black and white print only - colored inks may contain heavy metals, and shred it and soak it in water. Wring it out, fluff it up and put it into the bottom of the inner bin. Wad up some newspaper and put it semi snugly in the hole in the bottom of your bin. You want liquids to drip through but want to prevent red wiggler suicides. When your worms arrive, put them in their new home. If you have a good distributor, they will include some starter food with the worms. Harvesting worm poop depends upon how many worms and the size of the bin, the temperature and how much you feed them.
This is a good tip - if you want to avoid fruit flies, freeze your fruit and veggie scraps first, it kills the fruit fly eggs.
Worms like to be in the dark so keep the lid tightly on, put them under the sink, the bottom of a closet or drape some cloth over them. You now have a forever source of great fertilizer.
Oh, your new best friends will multiply if fed well, so you can split them and make another bin, or give them away.
