SUPERthrive Grow – Gallon

SUPERthrive Grow (formerly Dyna-Gro Grow 7-9-5) is a 1-gallon liquid concentrate that delivers all six essential macronutrients and all ten essential micronutrients in a single, urea-free formulation. Built for foliage and bloom growth across soil, container, and hydroponic systems, the 7-9-5 NPK ratio with a high nitrate-to-ammoniacal nitrogen balance promotes shorter internodes, sturdier stems, and a rapid recovery from nutrient deficiencies—without burning roots or forcing a mid-cycle formula switch.

Why Choose SUPERthrive Grow

The points below are drawn from the canonical product description, the SUPERthrive / Dyna-Gro brand label, and the research documentation compiled for this listing.

• Complete nutrition in a single bottle. SUPERthrive Grow contains all six essential macronutrients (N, P, K, Ca, Mg, S) and all ten essential micronutrients in one liquid concentrate. For growers who don’t want to track separate macro and micro bottles or measure multiple parts, this is a true single-formula feed—sixteen essential elements covered with no obvious nutrient gaps.
• Urea-free chemistry won’t burn plants. The 7-9-5 formula is built without urea, the cheap nitrogen source common in low-cost fertilizers that readily burns roots and foliage at high concentrations. By delivering nitrogen primarily as nitrate, SUPERthrive Grow gives plants a directly available nitrogen source and removes the urea-driven leaf tip burn that catches new growers off guard.
• High nitrate-to-ammoniacal ratio builds sturdier plants. Plants fed predominantly nitrate nitrogen grow with shorter internodal spacing and thicker, stronger stems compared to plants fed predominantly ammoniacal nitrogen, which stretches growth and produces softer tissue. For indoor growers under high-output lighting, that means more compact canopies that hold up to heavy flowering loads.
• Single formula for every growth stage. Unlike multi-part systems that require switching from a vegetative formula to a bloom formula mid-cycle, the 7-9-5 ratio is balanced for both foliage and bloom. Growers running short cycles, propagation operations, or mixed-crop gardens can run a single feed throughout the entire growing period.
• Rapid recovery from nutrient deficiencies. Because the formula carries every essential element rather than just NPK, it can address multiple visible deficiency symptoms—interveinal chlorosis, leaf-edge burn, slow new growth—at the same time, without a separate diagnostic to pick a specific corrective.
• Gallon size is sized for serious growers. At ¼–½ tsp per gallon for indoor maintenance, the 1-gallon (128 fl oz) bottle yields roughly 512–1,024 gallons of working solution—more than a year of continuous feeding for a single tent, with a significant per-ounce cost advantage over the 8 oz or quart sizes.
• Distributed by Hydrofarm with the Dyna-Gro heritage. SUPERthrive Grow is the rebranded Dyna-Gro Grow 7-9-5 formula, distributed by Hydrofarm. The formulation is unchanged from the long-running Dyna-Gro version used in commercial nurseries and orchid collections for decades—same product, new branding.

Best Uses for SUPERthrive Grow Gallon

SUPERthrive Grow Gallon is classified under Nutrients & Additives > Base Nutrients. The use cases below reflect the documented application as an all-purpose single-formula liquid feed across diverse growing systems.

• Hydroponic gardens running a single-part nutrient program. Run SUPERthrive Grow as the sole base feed in DWC, drip, ebb-and-flow, NFT, or aeroponic systems at 2–3 tsp per gallon (recirculating) or 1–2 tsp per gallon (non-recirculating). The complete micronutrient package eliminates the need for a separate trace-element supplement. If you are pairing with a root-zone inoculant, Advanced Nutrients Tarantula is a documented compatible additive.
• Container gardens and houseplants on a steady feeding schedule. Container plants, patio gardens, and houseplants benefit from a complete liquid feed at ¼–½ tsp per gallon at every watering. Urea-free chemistry removes the burn risk that comes with cheaper fertilizers, and the 16-element profile suits collections spanning vegetables, ornamentals, orchids, and tropicals on the same bench.
• Poor, rocky, or depleted soils that need rebuilding. SUPERthrive Grow is dosed lightly and frequently in soils that have lost their native fertility, restoring not just N, P, and K but also the Ca, Mg, S, and trace elements depleted soils typically lack. A useful baseline corrective for raised beds, rocky outdoor plots, and recycled potting mixes.
• Foliar spray applications for fast deficiency correction. At ¼–½ tsp per gallon, SUPERthrive Grow is approved for foliar use. Foliar feeding bypasses root-zone uptake limitations and delivers nutrients directly to leaf tissue—useful when correcting acute deficiencies during heavy fruiting. Rinse foliage with fresh water the next day to prevent salt buildup.
• Commercial production with siphon mixers and injectors. Formulated for siphon proportioners (1–3 fl oz per gallon concentrate) and irrigation injectors (10–18 fl oz per gallon concentrate). Greenhouse and nursery operations can use the 1-gallon bottle as a concentrate source feeding hundreds of plants from a single dilution system.
• Mixed-crop operations with overlapping cycles. The 7-9-5 ratio is balanced for both veg and bloom, so a single feed schedule covers seedlings, vegetative growth, transition, and flowering across cannabis, leafy greens, fruiting vegetables, and edibles. Run heavier-feeding crops alongside lighter ones by adjusting dose rate rather than switching products.
• Companion feed in amended-soil programs. Though a mineral-salt formulation rather than a certified organic input, SUPERthrive Grow is regularly used as a corrective top-feed alongside organic amendments and meals. Growers using Earth Juice Hi-Brix molasses as a soil-biology carbon source can pair the two when slow-release amendments aren’t keeping up with a visible mineral deficiency.

SUPERthrive Grow vs General Hydroponics Flora Series

The most common comparison for a complete single-bottle liquid feed like SUPERthrive Grow is the long-standing General Hydroponics Flora Series, a three-part system (FloraGro 2-1-6, FloraMicro 5-0-1, FloraBloom 0-5-4) that experienced hydroponic growers use to dial in stage-specific nutrient ratios. The two approaches solve the same problem—feeding the full 16-element nutrient profile—but they make very different demands on the grower. The table below compares them on the factors that drive a purchasing decision.

The decision comes down to how much control a grower wants over the nutrient ratio at each stage. Flora Series rewards growers willing to learn a multi-part feed schedule and re-balance ratios week by week. SUPERthrive Grow goes the other direction: a single fixed ratio that performs across the whole cycle without thinking about which bottle to reach for. For mixed-crop gardens or growers who want a lower-friction feed, the gallon is the simpler choice; for a single-crop production tent running a tightly optimized schedule, Flora Series still has the edge in tunability.

Compatibility & Operating Range

SUPERthrive Grow is a complete mineral-salt liquid concentrate, so compatibility considerations cover growing media, system type, reservoir chemistry, and interactions with the other inputs commonly used alongside a base nutrient feed.

• Growing media: Compatible with soil, peat-based potting mixes, coco coir, rockwool, expanded clay pebbles, perlite, and other soilless or inert media. The 16-element profile is particularly valuable in inert media where there is no native nutrient buffer—every element the plant needs must come from the feed.
• System compatibility: Works with deep water culture (DWC), drip, ebb-and-flow, NFT, aeroponics, and continuous-feed bench irrigation. Equally suited to hand-watered container gardens and hose-end siphon mixers for greenhouse production.
• pH range: Soilless and hydroponic systems target pH 5.5–6.5 (sweet spot 5.8–6.2); soil-based systems can run pH 6.0–7.0. The 7-9-5 formula does not strongly buffer the reservoir, so growers using high-alkalinity water may need a pH-down adjuster after the nutrient is mixed.
• EC and dose rate: At the indoor maintenance rate of ¼ tsp per gallon the EC contribution is light (well under 1.0 mS/cm); at the recirculating hydroponic rate of 3 tsp per gallon it lands in the typical hydroponic feed range (1.4–1.8 mS/cm depending on water source).
• Stacking with microbial and additive products: Bacterial inoculants like Advanced Nutrients Tarantula can be dosed into the same reservoir without affecting the SUPERthrive nutrient profile. Root-zone enhancers such as Heavy 16 Roots are similarly compatible, and molasses-based carbon sources can be layered in amended-soil programs.
• Inputs to avoid co-mixing: Do not mix SUPERthrive Grow concentrate directly with concentrated Ca-Mg supplements, concentrated phosphoric acid pH-down, or strong oxidizers (hydrogen peroxide, bleach). Always dilute the base feed into the reservoir water first, then add other concentrates one at a time. Combining concentrates can precipitate insoluble salts.
• Water source & reservoir temp: Reverse-osmosis water gives the most predictable results; dechlorinated tap water can be used but contributes background Ca, Mg, and bicarbonate that should be accounted for. Maintain reservoir water at 65–72°F (18–22°C) for best uptake and to limit root pathogens.
• Storage: Keep the gallon out of direct sunlight to prevent algal growth and degradation of chelated micronutrients. Cool storage or refrigeration extends shelf life; store above 40°F (4°C) in winter.

Dosing & Usage Guidelines

SUPERthrive Grow uses a single 7-9-5 formula across every growth stage, but the dose rate changes meaningfully depending on growing system, crop intensity, and whether you are running maintenance or production feeding. The table below summarizes the documented dose rates by application method, all on a per-gallon-of-working-solution basis unless otherwise noted.

Bottle-yield reference: At the indoor maintenance ¼ tsp/gal rate, the 1-gallon bottle yields ~1,024 gallons of working solution; at ½ tsp/gal, ~512 gallons. Even at the heaviest hydroponic 3 tsp/gal rate it still mixes nearly 85 gallons of reservoir-strength feed—four refills of a 20-gallon DWC reservoir.

How to Mix and Apply SUPERthrive Grow

The steps below walk through a complete mix-and-apply cycle for SUPERthrive Grow, with notes on container gardens and hydroponic reservoirs. The procedure is forgiving relative to multi-part nutrient systems, but the same hygiene—clean water, accurate measurement, mix before applying—applies.

1. Shake the bottle gently before measuring. Trace elements can settle slightly during long storage; a quick inversion ensures consistent micronutrient delivery from the first dose to the last.
2. Fill your watering can, reservoir, or feed tank with clean water. Use dechlorinated tap water, reverse osmosis water, or well water free of contaminants. Tap water should off-gas 24 hours or pass through a carbon filter; chlorine and chloramine degrade trace-element chelates.
3. Measure the dose for your application. Refer to the dose table above and measure with a calibrated measuring spoon or graduated pipette. Container gardens at indoor maintenance: ¼–½ tsp per gallon. Hydroponic reservoir, recirculating: 2–3 tsp per gallon.
4. Pour the concentrate into the water, not the other way around. Add concentrate to water, then stir or run the reservoir pump to disperse. Adding water to undiluted concentrate produces uneven mixing and pockets that can contact plant tissue too strong.
5. Stir or run the pump to fully dissolve. Stir a watering can for 10–20 seconds; run a hydroponic recirculation pump for 5–10 minutes before reintroducing the feed to the plants.
6. Check and adjust pH after mixing. Target pH 5.8–6.2 for hydroponic and soilless systems; pH 6.0–7.0 for soil. The 7-9-5 formula does not strongly buffer the reservoir, so adjustments hold cleanly.
7. Apply to the root zone or foliar canopy. Water container and soil gardens at the base until light runoff appears. Fill hydroponic reservoirs to working level. For foliar, spray to wet leaf surfaces evenly and rinse with fresh water the next day.
8. Hold off feeding stressed or freshly transplanted plants. Allow new transplants 3–5 days of plain water before introducing nutrient feed. Heat-stressed or root-damaged plants should also recover on plain water before resuming full strength.
9. Track plant response and adjust dose over time. Watch for leaf-tip burn (overfeeding) or interveinal yellowing (underfeeding or pH lockout). Adjust by ¼ tsp per gallon at a time and observe over 5–7 days before changing again.
10. Refresh hydroponic reservoirs regularly. Drain and refill with fresh nutrient solution every 1–2 weeks even in recirculating systems. Plants deplete some elements faster than others, throwing the reservoir off-balance even when total EC looks unchanged.
11. Store the bottle correctly between feedings. Cap securely after each use. Keep out of direct sunlight in a cool location; refrigeration optional but extends shelf life. The original bottle protects against light degradation of the chelates.
