What’s Inside the Stash System

Stash Base 2.2–4.0–2.3
A dry soil amendment and vegetative fertilizer designed to build rich, biologically active media.

  • Supports strong vegetative growth and root development
  • Broad spectrum nutrition with nitrogen, phosphorus, potassium, calcium, iron, organic biochar, crustacean and fish meals, alfalfa, insect frass, kelp, neem seed kernel meal, oyster shell dust, volcanic and glacial rock dusts, and more
  • Includes slowly released nitrogen to help sustain plants over time

Stash Bloom 2.0–8.0–6.0
A bloom-focused fertilizer that powers flower development and quality.

  • Higher phosphorus and potassium to drive flowering, stacking, and color
  • Added calcium for strong cell walls and structural integrity
  • Formulated from sulfate of potash, calcium sulfate, fish bone meal, alfalfa meal, insect frass, and volcanic calcium metasilicates

Stash Blend 2–1–5 Premium Plant Additive
A bioactive additive that supercharges the entire program.

  • Corn steep liquor and seaweed extract for NPK and natural potassium
  • Humic acid (from Leonardite) to improve nutrient uptake and soil structure
  • Soluble silicon for plant strength and stress resistance
  • Four beneficial bacterial species to support nutrient cycling and soil vitality
  • Endo mycorrhizae (Glomus species) to enhance root function and nutrient absorption

How to Use the Stash Nutrient System

All rates are based on 1 gallon of growing media or soil and can be adjusted by crop type and cultivar.

As a Soil Amendment

  • Incorporate Stash Base, Stash Bloom, and Stash Blend at their amendment rates into fresh soil or media.
  • Mix thoroughly to ensure even distribution.
  • Compatible with a wide range of organic and non-organic fertilizers and media types.

Top Dress Fertilization

  • Broadcast Stash (Base & Bloom) fertilizers over the surface of existing pots or beds.
  • Lightly work into the top layer of media.
  • Irrigate thoroughly so the entire pot or bed is saturated.

Side Dress Fertilization

  • Place fertilizer in a trench or furrow 3–6 inches from the main stem and 2–4 inches deep.
  • Water so the side-dressed zone and root zone are fully saturated.

Stage-Specific Program (per 1 gallon of media)

Stash Base

  • Soil Amendment: 2½ Tbsp
  • New/Young Plants: 1½–2½ Tbsp
  • Vegetative Rate: 3–4 Tbsp
  • Flowering Rate: N/A

Stash Bloom

  • Soil Amendment: 1 Tbsp
  • New/Young Plants: ½–1 Tbsp
  • Flowering Rate: 2½–4 Tbsp

Stash Blend

  • Soil Amendment: 1 Tsp
  • New/Young Plants: 0.5 Tsp
  • Vegetative Rate: 0.5 Tsp
  • Flowering Rate: 1 Tsp

Tablespoon values are approximate, assuming ~10 g dry fertilizer per 1 Tbsp.

Liquid mixing for Stash Blend:

  • Mix ½–1 Tsp per gallon of water
  • Add Blend last when mixing with other nutrients

Veg and Bloom Strategy

  • Vegetative Stages

    • Amend soil or media with Stash Base before planting.
    • Top dress or side dress with Stash Base as needed every 2–3 weeks.
    • Add Stash Blend to boost vigor, root health, and nutrient uptake.
    • Small additions of Stash Bloom can help younger plants establish in new pots or beds.
  • Flowering Stages

    • Transition from Stash Base to Stash Bloom as plants enter bloom.
    • Apply Stash Bloom every 2–3 weeks at the recommended flowering rate.
    • Continue using Stash Blend to support metabolites, resin, and overall plant quality.
    • Gradually taper off fertilization as plants reach the desired stage of senescence.
