Earth Juice Grow is a natural-organic liquid base nutrient for the vegetative stage with a 2-1-1 guaranteed analysis (2% N, 1% P₂O₅, 1% K₂O). It is non-burning with no salt residue and is designed for hand-feeding applications, indoors or out. This listing is the bulk 5 US gallon (20 L) size. This page gives the retailer-published specifications, explains how the organic feed becomes available to the plant, and is honest about what is not published — all cited. It is a base nutrient in the Nutrients & Additives range, not a bloom booster or additive.
What it is
Earth Juice Grow is one of the recognisable natural-organic liquid feeds sold under the Earth Juice brand (the brand’s site, earthjuice.com, now redirects to Pennington, which carries the line). It is a nitrogen formulation for vigorous green vegetative growth — stem and leaf development — rather than a flowering feed. The 2-1-1 NPK is delivered from oat bran, sea kelp, bat guano, steamed bone meal, natural potash, blood meal and feather meal — recognizable whole-ingredient organic sources rather than concentrated mineral salts. Because it is non-burning with no salt residue, it is more forgiving of dose error than a synthetic veg base. This listing is the bulk 5 US gallon (20 L) jug, the format aimed at growers who already know the product and want to buy the veg base in volume.

Why choose Earth Juice Grow
- Whole-ingredient organic sourcing. The 2-1-1 analysis comes from named organic inputs — oat bran, sea kelp, bat guano, steamed bone meal, natural potash, blood meal and feather meal, so you can see where the nitrogen, phosphate and potash originate rather than reading a salts blend.
- Non-burning, low-salt chemistry. Because it is non-burning with no salt residue, the feed is more forgiving of over-dosing than a concentrated synthetic veg base and does not leave a salt crust in the root zone.
- Built for hand-feeding at any scale. It is designed for hand-feeding indoors or out, which suits soil, planting-mix and container growers who feed from a watering can.
- Bulk economy. The 5 US gallon (20 L) jug is the volume format for growers who go through veg base steadily and want to buy it in one container rather than re-ordering quart or one-gallon bottles.
How an organic liquid feed becomes available to the plant
An organic feed like Earth Juice Grow does not act the way a synthetic mineral salt does. The nitrogen in its organic inputs is not immediately in a mineral form the roots can take up. Penn State Extension explains that soil microbes play a vital role in how much nitrogen becomes available to plants: as they break down organic residues they either immobilize nitrogen, making it unavailable, or mineralize it — releasing ammonium, a mineral form that is available for plant uptake. That is why an organic base is typically used in a living soil or planting mix where a microbial community is present to do that conversion, and why the feed’s forgiving, non-burning character matches a soil-and-coir hand-feeding style rather than a sterile recirculating reservoir.
Best uses
- Vegetative-phase hand feeding in soil or planting mixes. The primary use: mix at the 1 to 3 Tbsp per gallon of water and apply with every watering through the vegetative cycle, indoors or out.
- Organic soil and container gardens. Because it is a natural-organic liquid feed, it fits growers running a soil or planting-mix program who want an organic nitrogen source for early growth rather than a synthetic salts base.
- Bulk-volume feeding. The 5 US gallon (20 L) size suits multi-plant indoor rooms or outdoor container and raised-bed gardens where the smaller bottles would be re-ordered frequently.
Compatibility and handling notes
- Hand-feed only. It is designed for hand-feeding applications. Natural-organic liquids carry suspended particulate from ingredients like bone meal and kelp, so they are not intended for drip emitters, misters, or recirculating hydroponic reservoirs where fine orifices clog and organic matter destabilises reservoir chemistry.
- Shake before measuring. Heavier organic solids settle out of a natural feed; agitate the jug (or a decanted working bottle) before drawing a dose so the working strength stays consistent.
- Layer microbial inoculants separately. An organic liquid base supplies the NPK; the microbial mineralization it relies on happens in the medium. Root-zone inoculants and biostimulants can be run on their own schedule alongside it. This listing is a base nutrient, not an additive.

Frequently asked questions
What is the NPK? 2-1-1 — 2% nitrogen, 1% phosphate, 1% potash, a vegetative-stage ratio weighted to nitrogen.
How much do I use? 1 to 3 Tbsp per gallon of water, applied with every watering. Start at the low end and step up as the plant establishes.
Can I run it in a hydroponic reservoir? No — it is designed for hand-feeding only, not automated or recirculating hydroponic systems.
Will it burn my plants? It is listed as non-burning with no salt residue, which gives a wider margin than a concentrated synthetic base — though any feed can over-concentrate if heavily overdosed.
Who this is for — and who should skip it
Suited: soil, planting-mix and container growers who hand-feed and want a natural-organic liquid nitrogen base for the vegetative stage, and who go through enough veg feed to justify the 5 US gallon (20 L) bulk jug.
Not suited / its limits: it is hand-feed only — not for drip, aeroponic, NFT or recirculating hydroponic systems. It is a vegetative feed, not a flowering base, so a bloom-stage product is needed for the flowering phase. Its 2-1-1 ratio is low-concentration, so growers wanting a high-nitrogen push may prefer a stronger feed.
Source-tier note. The Earth Juice maker site (earthjuice.com) now redirects to Pennington and its product page did not return a spec sheet this session, so every value above is grounded to the carrying retailers Planet Natural and Sunset Hydro, which reproduce the label and resolve for a visitor. The 5 US gallon size is the retailer-listed size; the “20 L” on this listing is the nominal metric label (5 US gallons is about 18.9 L).
Items held (not sourced this session, not stated as fact): the exact SKU / UPC; OMRI certification status; the calcium percentage (steamed bone meal contributes calcium, but no figure was sourced); the per-litre dose and any finer mild / medium / strong tier breakdown beyond the 1–3 Tbsp per gallon range; target feed-pH numbers; shelf life; pet-safety; the “since 1991” heritage claim; and the live retail price (the storefront price field is the source of truth at deploy). None were reproduced here because no source read this session stated them as figures we could publish.
