The mineral-and-carbon foundation your plants build on, mixed in once.
Stash Base is an all-natural dry amendment that turns fresh or reused media into a mineral- and carbon-rich foundation for vegetative growth. Rather than a liquid grow feed, it is worked into your soil, where a broad set of natural inputs feeds steady growth and strong roots as the soil biology breaks them down. It is the veg half of the Stash program, the base you build before flipping to Stash Bloom. Mix it in, plant, and grow.
A liquid grow schedule vs. Stash Base
- Separate bottles for grow, cal-mag, and micronutrients
- Mix fresh nutrient water for every watering in veg
- Grow concentrates are mostly water, heavy to ship and quick to empty
- Salt-based feed can build up and stress young roots
- Feeds the plant but does nothing to build the soil itself
- Empty coco or soil starts from zero every single run
- One dry amendment covers veg nutrition and calcium
- Work it in at the start, then just add water
- A dry bag ships light and lasts across a whole grow
- All-natural, slow-release inputs feed gently with little burn risk
- Builds a living, mineral-rich medium that gets better each cycle
- Leaves you with reusable soil you can recharge and replant
How Stash Base builds veg and the medium
A strong vegetative stage starts with the medium, not just the feed. Stash Base uses biochar and glacial and volcanic rock dusts to do the structural work. The biochar acts like a sponge and a reef at once, holding water and nutrients and giving soil microbes a place to live, while the rock dusts slowly release the wide range of trace minerals plants draw on across a full cycle.
On top of that structure, marine, fish, and plant inputs supply the nitrogen, phosphorus, and calcium that leaf, stem, and root growth need. Because that nitrogen is mostly slow-release and water-insoluble, it feeds gradually as soil biology mineralizes it, which keeps vegetative growth steady and makes it hard to burn young plants. You end up with a medium that is fed and alive before the plant even asks for it.
What Stash Base does for veg
A veg feed and a soil upgrade in one bagVeg + soil builder
One all-natural amendment feeds vegetative growth and rebuilds the medium at the same time, so you are not running a grow bottle, a cal-mag, and a separate soil conditioner. Mix it in at the start of the run.
Calcium built in, where veg often runs short6.9% Ca
Calcium is easy to run low on in veg. Stash Base carries a solid dose of it to support sturdy stems and healthy new growth, and it helps buffer the soil at the same time.
Kelp and neem, not just NPKMarine + botanical
Beyond the big three, it brings giant kelp meal for natural growth compounds and trace elements, plus neem seed meal, a botanical input that supports a cleaner, more resilient root zone.
Feeds the whole veg stage, hands-offWeeks per feed
Amend once and most of the work is done. It keeps releasing through veg, so you top-dress only every few weeks instead of mixing a grow feed at every watering.
Turns soil into a reusable assetReusable media
Instead of spent, salt-heavy soil at the end of a run, you get an amended, living medium. Recharge it and replant, and your cost per cycle drops with every reuse.
Works in soil, coco, and next to your lineSoil and coco
Run it in soil, living soil, or coco, on its own or alongside the base nutrients you already trust. It works the same in a hand-watered pot as it does in a raised bed.
Stash Base by the numbers
What's in the bag
Ingredients: calcium phosphate, biochar, crustacean meal, feather meal, fishbone meal, glacial and volcanic rock dusts, alfalfa, insect frass, giant kelp meal, neem seed kernel meal, oyster shell dust, sulfate of potash, calcium carbonate, and fish meal. Because it includes fish, crustacean, and feather meals, Stash Base is not vegan, and it carries the earthy smell natural amendments tend to have.
How to feed with Stash Base
Amend fresh or reused media
Mix Stash Base into your soil or coco at about 2.5 tablespoons per gallon of media before planting. If you can, let it sit and moisten for a few days so it starts breaking down.
Start seedlings gently
Rather than seeding straight into freshly amended soil, dig a small hole and start seeds or young plants in a mild seed-starting mix, then let the roots reach the amended soil as they grow. This keeps tender seedlings from burning.
Feed through veg
As plants establish, top-dress the veg rate of 3 to 4 tablespoons per gallon of media every two to three weeks, lightly work it into the surface, and water as normal.
Switch to Bloom at the flip
When plants move into flower, stop feeding Base and transition to Stash Bloom for the flowering stage. The amended soil stays productive underneath.
