What it does

Turns a canning jar into a sprouting kit
Grows radish, clover, bean, and other healthy sprouts
Drops onto standard mason jar threads
Saves money on store-bought sprouting kits
Pairs with a mesh screen for proper drainage

You add the sprouting lid to a mason jar and grow fresh sprouts on the kitchen counter. Radish, clover, bean, alfalfa: this lid handles all of them, with drainage that supports the rinse-and-drain cycle sprouts need.

The lid threads onto a standard mason jar, so you can use jars you already own. Pair it with a fine mesh screen between the lid and the jar threads for proper drainage and clean rinses.

Use it for kitchen herbs, salad sprouts, and homegrown microgreens.
