SUPERthrive – pint

SUPERthrive is a non-toxic vitamin solution designed to work directly on seeds and roots to encourage vigorous root development and more robust plant growth. The pint size delivers the same highly concentrated formula — 1 tablespoon treats 15 gallons — now enhanced with kelp for additional nutrition. It is compatible with any fertilizer program and suited to all growing environments.

Why Choose SUPERthrive Pint

SUPERthrive has been used by growers for decades. Here is what distinguishes this product based on its documented formula and characteristics:

• Broad-spectrum vitamin formula: SUPERthrive delivers 50 biousable normal pure complexes to the root zone, supporting both germination and established plants at all growth stages.
• Kelp enrichment: The current formula includes kelp, adding natural sea-derived nutrition alongside the original vitamin base. This makes SUPERthrive useful beyond a simple vitamin supplement.
• Extremely high concentration: At 1 tablespoon per 15 gallons, a single pint bottle provides enough concentrate for approximately 240 gallons of solution — making it economical for regular use in a home or commercial grow.
• Non-toxic and non-pesticide: Safe to handle and classified as non-polluting, making it compatible with organic and conventional feeding programs alike.
• Works at transplant and rooting stages: The formula acts directly on seeds and roots, making it particularly useful during transplanting, cloning, and any stage where root establishment is the priority.

Best Uses for SUPERthrive Pint

SUPERthrive is categorized as a growth and bloom booster additive. These are the scenarios where growers most commonly reach for it:

• Transplanting: Add to the water or nutrient solution immediately before and after transplanting to reduce transplant shock and support fast root re-establishment.
• Seed soaking and germination: A dilute solution applied during seed soaking or early germination encourages faster, more vigorous root emergence.
• Cloning: Apply to cloning water to support cutting survival and root initiation before transfer to a rooting medium.
• Routine feedings as an additive: Add to any existing fertilizer mix — whether soil, hydroponic, or coco — without altering the base nutrient program. Pair with a root inoculant such as Advanced Nutrients Tarantula for a combined microbial and vitamin approach to root development.
• Recovery from stress: Use after pest damage, nutrient lockout, or environmental stress events to help plants resume normal growth.
• Foliar application: Can be diluted and applied as a foliar spray during vegetative growth when rapid recovery or additional nutrition is needed.

Compatibility

SUPERthrive is designed as a universal additive that works alongside fertilizers, not as a standalone feed. The following covers what the canonical product data confirms about its compatibility:

Growing media: SUPERthrive is suitable for use in soil, soilless mixes, coco coir, rockwool, and hydroponic systems. Because it is a vitamin solution rather than a nutrient concentrate, it does not meaningfully shift EC or pH in properly mixed solutions at the recommended dose.

Fertilizer programs: Compatible with all fertilizer types — synthetic or organic, single-part or multi-part. Add it to the reservoir or watering can alongside your regular nutrient mix. For growers using a comprehensive root-zone product such as Earth Juice Hi-Brix Molasses as a carbohydrate supplement, SUPERthrive can be added in the same feeding without issue.

Growth stages: The formula is documented as suitable for use from seed through harvest, including during propagation and transplanting phases where its vitamin action is most directly useful.

Mixing note: Always add concentrated supplements to water, not water to concentrates. Measure with a dedicated syringe or measuring cup and add to the reservoir before or alongside other inputs.

Dosing Guidelines

The canonical product data provides the following application rate for SUPERthrive:

Standard rate: 1 tablespoon (approximately 15 mL) per 15 gallons of water or nutrient solution. This is the recommended rate stated on the product for general use.

At this concentration, the pint bottle (16 fl oz / approximately 473 mL) contains roughly 31 tablespoons, giving approximately 465 gallons of treated solution from a single pint.

Transplant and stress applications: Some growers apply SUPERthrive at the standard rate immediately before and after transplanting, and again at the first feeding after a stress event. The formula’s vitamin complexes work through root absorption, so direct root-zone application is the most effective delivery method.

Foliar use: When applying as a foliar spray, use at or below the standard dilution rate. Apply early in the light cycle to allow foliage to dry before the dark period.

Always measure concentrate accurately. The formula is highly concentrated; there is no documented benefit to exceeding the stated dose rate.
