Red Wiggler Worm + Cocoon Starter Mix: Everything Your Bin Needs to Get Going

Fed 'n Happy Starter Mix is perfect for anyone starting their very own worm farm, Johnson-Su bioreactor or composting bin, and for the vermicomposter who wants to increase their operation's capabilities.

Our mix is made up of 1/4" castings along with cocoons and juvenile Red Wigglers, and it's brimming with microbes to get your bin's microbiome started. It all comes from the same worms that produce every Fed 'n Happy product, raised on our Hutchinson, KS and Central Iowa farms.

The best start you can give your composting operation.

Frequently Asked Questions

How many worms are in the mix?
Naturally, the worm count and size vary by season, but we can guarantee our mix is the best start you can give your composting operation.

What's the difference between Starter Mix, Cocoons and Live Worms?
Starter Mix combines castings, cocoons and juvenile worms to start a bin or bioreactor. Cocoons are the most economical way to seed or grow a population. Live Worms are adult worms by the pound, ready to start composting right away.

Do Red Wigglers need to be refrigerated?
No. Red Wigglers do best at about 60–80°F, so room temperature is ideal. They slow down below about 50°F and start to die above about 85°F, so keep them out of direct sun and away from heaters.

How is Starter Mix shipped, and what does FOB Hutchinson mean?
You can pick up your order at our Hutchinson, KS facility, or we can arrange shipping. FOB (Free on Board) Hutchinson means ownership and responsibility pass to you once the carrier picks up and signs for the order at our dock. From that point you own the product in transit, and any freight damage claims go through the carrier.
