Dyna-Gro Grow is an all-purpose liquid base nutrient with a guaranteed analysis of 7-9-5 (N-P-K), a single complete formula that contains all six essential macronutrients and all ten essential micronutrients that every plant needs — 16 essential plant nutrients in one bottle. This listing is the 5-gallon size. It is a liquid mineral concentrate used to promote both foliage and blooms, marketed by the maker as a one-formula feed for soil, soilless media, and hydroponics. This page gives the published guaranteed analysis, the container size, and the maker’s dilution directions, and is honest about the details the sources read do not publish. It is a concentrated liquid nutrient you dilute in water — not a dry amendment or a ready-to-use spray.
What it is
Dyna-Gro Grow (now sold under the SUPERthrive brand) is the vegetative “grow” formula in the Dyna-Gro complete-nutrition line. Rather than a multi-bottle A/B program, it is a single all-purpose, nutritionally complete formula used to promote both foliage and bloom growth. The maker’s guaranteed analysis is 7-9-5, a slightly higher-phosphorus-to-nitrogen ratio that the maker describes as suited to poor and rocky soils, container-grown plants, and hydroponics. Because it carries the full complement of macro- and micronutrients in one product, it is intended to be used on its own rather than layered with additional base bottles. The container here is the 5 gallon size, a bulk format for growers feeding many plants or running larger reservoirs.
Every plant requires a set of essential mineral nutrients — the macronutrients nitrogen, phosphorus, potassium, calcium, magnesium and sulfur, plus micronutrients such as iron, manganese, zinc, copper, boron and molybdenum — to complete its growth cycle, which is why a “complete” formula that supplies all of them can serve as a stand-alone feed in an inert or depleted medium.
Guaranteed analysis and specifications
The guaranteed analysis below is reproduced from a carrying retailer that prints the maker label in full; percentages marked as guaranteed follow the maker’s published figures.
| Guaranteed analysis (N-P-K) | 7-9-5 |
|---|---|
| Total Nitrogen (N) | 7% (2.6% ammoniacal, 4.4% nitrate) |
| Phosphorus (P2O5) | 9% |
| Potassium (K2O) | 5% |
| Calcium (Ca) | 2% |
| Magnesium (Mg) | 0.5% |
| Sulfur (S) | 0.05% |
| Micronutrients | Boron 0.02%, copper 0.05%, iron 0.1%, manganese 0.05%, molybdenum 0.0009%, zinc 0.05% |
| Essential nutrients supplied | 16 (all six macronutrients and all ten micronutrients) |
| Form | Liquid concentrate (dilute in water before use) |
| Container size | 5 Gallon |
| Retailer SKU | 719007 |
The maker notes that nutrients marked as guaranteed are assured in all states, while the remaining trace minerals are held at levels ideal for crop growth but sometimes below individual state labeling thresholds — so a few micro figures (such as cobalt, sodium, and nickel) appear on the label as ideal concentrations rather than state-guaranteed minimums.
Why choose it
- One complete formula. It is a single all-purpose complete formula, so you can feed everything from vegetables to houseplants without buying and mixing separate base bottles.
- Full micronutrient package. With 16 essential nutrients, it supplies calcium, magnesium, sulfur, and the trace metals in the same bottle, which the maker positions as a fast correction for nutrient deficiencies in poor or depleted media.
- Flexible across media. The maker lists it for poor and rocky soils, container-grown plants, and hydroponics, including foliar spraying and use through injectors or siphon mixers.
- Bulk size. The 5-gallon jug suits growers running multiple reservoirs or feeding a large plant count who want to buy the concentrate in volume.
Best uses
- Hydroponics and soilless media. As a complete liquid mineral feed it works in recirculating and drain-to-waste systems and in inert media such as coco or rockwool, where the plant relies entirely on the nutrient solution.
- Container and houseplants. The maker highlights it as an all-year formula for container plants, including African violets and orchids, thanks to the low soluble salts and the slightly higher phosphorus.
- Poor or depleted soils. It is marketed to replenish minerals in rocky or depleted ground where a complete, readily available feed helps correct deficiencies.
Compatibility and systems
Because it is a liquid concentrate that can be used with fertilizer injectors, siphon mixers, and soilless mediums, it fits standard hydroponic reservoirs, hand-watering, drip, and injector-fed setups. It is a mineral salt nutrient, so it is diluted into the water supply rather than applied dry. As with any concentrated salt feed, growers monitor solution strength and pH for their crop; the specific EC and pH feed targets are not published on the sources read here and are HELD below.
Dosing and dilution (maker directions)
Follow the label directions for your setting. The published dilution rates are:
- Houseplants / indoor: 1/4 to 1/2 teaspoon per gallon of water with every watering.
- Outdoor / garden: 1 teaspoon per gallon of water, once a week.
- Hydroponics: 2 to 3 teaspoons per gallon for recirculating systems, or 1 to 2 teaspoons per gallon for non-recirculating systems.
- Foliar spray: 1/4 to 1/2 teaspoon per gallon of water sprayed directly on the leaves.
- Injector concentrate: a 1:15 concentrate at 2 to 4 fluid ounces per gallon, or a 1:100 injectable concentrate at 10 to 18 fluid ounces per gallon.
Mix into water and apply as you would any liquid feed; do not apply the concentrate undiluted.
Comparison
| Attribute | Dyna-Gro Grow 7-9-5 | Typical multi-part base program |
|---|---|---|
| Bottles to feed | One complete formula | Two or more parts mixed in sequence |
| N-P-K | 7-9-5 | Varies by part and stage |
| Micronutrients included | All 16 essentials in one bottle | Often split across parts / supplements |
| Form | Liquid mineral concentrate | Liquid or dry, varies |

Frequently asked questions
What is the NPK? The guaranteed analysis is 7-9-5.
Is it a complete nutrient? Yes — the maker states it contains all six essential macronutrients and all ten essential micronutrients, a total of 16 nutrients.
Can I use it in hydroponics? Yes — the maker directs 2 to 3 teaspoons per gallon for recirculating systems, or 1 to 2 teaspoons per gallon for non-recirculating systems.
How big is this size? 5 gallons.
Who this is for — and who should skip it
Suited: growers who want one complete 7-9-5 liquid feed for soil, soilless media, or hydroponics, and who need the concentrate in a bulk 5-gallon size.
Not for / its limits: it is a concentrated mineral-salt liquid, not a dry amendment or a ready-to-use product, and it must be diluted before use. Despite the store’s category filing, the sources read do not present it as an OMRI-listed or certified-organic input — its guaranteed analysis is a mineral formulation — so it should not be treated as an organic-program input on the basis of this page. A grower committed to certified-organic inputs should look elsewhere or verify certification directly.
HELD (not stated because not sourced this session): any organic / OMRI certification; the maker “derived from” ingredient statement; the maker part number; recommended EC and pH feed targets; shelf life; the warranty term (held per policy); and the live retail price (the storefront price field is the source of truth at deploy). The guaranteed analysis and dilution rates are reproduced from carrying retailers because the maker’s own product page now redirects to a storefront that does not serve the label in machine-readable text.
