RegulaWorm, acidity regulator / lime blend

Yes! RegulaWorm is a 100% natural lime-based blend. Its granules dissolve in just a few minutes and work faster than regular lime. It also gives your worms the minerals they would normally find in the soil, so they're more active and breed more easily.

It's a great alternative to eggshells if you're vegan or don't eat eggs: one spoonful a week is all you need.

RegulaWorm's best companion is our pH Test: its strips tell you in seconds whether your worm composter is well balanced, so you can dose accurately instead of guessing. Your worms prefer a neutral environment.

If you'd rather take care of all your maintenance needs at once, our 5-Accessory Pack includes 2.2 lb (1 kg) of RegulaWorm, two hemp mats, WormFood, WORMboost, and a mini rake. You'll find all our tips in our guide: "Which accessories does your worm bin need?"

RegulaWorm comes in bags of 2.2 to 6.6 lb (1 to 3 kg) and in a 13.2 lb (6 kg) tub. At one 0.7 fl oz (20 ml) scoop a week, even a small size lasts a long time in a family worm composter. A 2.2 lb (1 kg) bag is also included in the 5-Accessory Pack.

Store it in a dry place, away from light and moisture, with the packaging tightly closed.

Add a small handful of RegulaWorm each week, which is about one 0.7 fl oz (20 ml) measuring spoon. Sprinkle it over the active tray (the top one) when you add your food scraps.

Don't use more than you need, because too much can also throw off the pH. To fine-tune the amount, check the acidity from time to time with our pH Test. RegulaWorm granules dissolve in just a few minutes, so they work faster than regular garden lime.

Yes, RegulaWorm is an excellent substitute for crushed eggshells: both help regulate acidity and provide calcium. The advantage is that it works faster, and there's nothing to crush.

If you use eggshells, grind them into a powder: worms can't eat whole shells because they have no teeth. There's no need to use both in large amounts. Choose one or the other, and add a little every week.
