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.

All-Natural Dry Inputs Veg Nutrient + Soil Builder Soil, Living Soil, Coco Made in the USA
Built by growers, not a marketing department. Stash Nutrients was developed by the home growers behind the From the Stash podcast, Mr. Grow It, Pigeons 420, and Rob from CLTV, working with a professional nutrient chemist. Stash Base is the vegetative and soil-building formula from that line, made in the USA.

Why it's different

A liquid grow schedule vs. Stash Base

Liquid Grow Schedule
  • 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
Stash Base (Dry)
  • 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.

Why growers run 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.

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

1

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.

2

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.

3

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.

4

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.

Questions

Before you buy

For most soil and coco grows, it is enough on its own through veg. Stash Base supplies nitrogen, phosphorus, potassium, calcium, and a broad set of trace minerals, so you can amend and grow without a separate grow bottle. If you like a specific liquid line, you can still run it, since Stash is compatible with organic and synthetic nutrients.
It works in soil, living soil, and coco. In coco, use a lighter up-front mix and lean more on top-dressing as plants grow, since coco holds fewer nutrients than soil. It is not made for deep water culture or other pure-hydro reservoirs, because it is a dry amendment that releases as it breaks down.
Go easy at the start. Freshly amended soil can be strong for tender seedlings, so start them in a mild seed-starting mix and transplant into the amended soil once they have a few sets of roots, or use the lighter young-plant rate when you mix. Established plants handle the full rate fine.
It is measured per gallon of media, so your total depends on container count and how much soil you are building. As a rough guide, a tablespoon of dry amendment is about 10 grams, so a 5-gallon pot amended at the mix rate uses a little under a cup. For an exact number for your setup, call us and we will work it out with you.
Every input is natural, and it is a strong fit for living-soil and no-till beds, where it amends and remineralizes the bed between runs. We do not claim a specific certification on this page, so if you need a certified input for a particular program, call us first and we will confirm the current label with you before you order.
It has the earthy, mealy smell natural dry amendments carry, strongest right after you water it in. Mixing it into the soil rather than leaving it on the surface keeps the smell down and keeps it from drawing fungus gnats or other surface pests.
