If extract is your go-to, stop buying it one gallon at a time.
The Underground Case puts four gallons of worm castings extract in your hands at once — enough to treat large areas, run a full application schedule, or keep on hand for when your plants need a fast response. Made on demand from our own worm castings, the extract delivers concentrated biological activity directly to the root zone and foliage without the wait.
Worm castings extract is the liquid version of everything castings do — microbial life, soluble nutrients, and natural growth stimulants — in a form plants can use immediately. Mix with water and apply by spray, drip line, or direct soil drench. Works on anything that grows.
Best used for:
- Regular feeding schedules for large plantings
- Fast foliar applications when plants are under stress
- Growers who already use castings and want extract to match
- Anyone who wants liquid soil biology on demand
