Description

Superthrive Super Thrive is a concentrated plant vitamin solution made for transplanting, propagation, and ongoing plant vigor across a wide range of garden and hydroponic setups. It’s a plant tonic-style input for growers who want simple support around root development and stressful transitions.

This formula is built around kelp-derived plant nutrition and a small nitrogen profile, with an NPK of 0.5-0-0. It’s derived from kelp and includes thiamine hydrochloride (B1), giving you a compact, recognizable ingredient story without turning into a heavy fertilizer. If you’re looking for a gentle, low-number option that still brings a defined nutrient identity, this is that category.

Where this product stands out is in what it’s positioned to do for the plant. It helps root development, builds plant vigor, and helps reduce transplant shock, including for larger, established plantings. Those benefits make it a natural fit when you’re moving plants into a new container, resetting a garden bed, or keeping valuable ornamentals steady through handling and environmental swings.

It’s also broad in plant scope. The label calls out indoor plants and outdoor plants, along with flowers, seedlings, and trees and woody plants. It also names lawns and sports turf, plus orchids, making this a flexible option when your collection includes everything from houseplants to landscape projects. For growers who like one dependable “support” bottle that can show up in many parts of the garden, that versatility is a key buying reason.

System-wise, it’s listed for hydroponics and propagation, and it also references foliar spray on the label, which makes it suitable for foliar application where that approach is part of your routine. Additional listed application areas include hydroseeding, landscaping, reforestation, and water gardens, reinforcing that this is meant to travel well between different growing styles rather than being locked into a single niche.

This is a good fit for growers who want a kelp-derived plant vitamin solution with a low NPK and clear transplant-and-vigor positioning, especially for mixed plant collections that span indoor plants, outdoor plants, and propagation-focused work.

How To Use

How to Use Superthrive Super Thrive - 4 OZ

Step-by-step mixing and feeding instructions for Superthrive Super Thrive - 4 OZ.

Mixing & preparation

Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Superthrive Super Thrive - 4 OZ well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.

Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

  • Week 4: mix 0.33 ml per litre of water or nutrient solution.
  • Week 5: mix 0.33 ml per litre of water or nutrient solution.
  • Week 6: mix 0.33 ml per litre of water or nutrient solution.
  • Week 7: mix 0.33 ml per litre of water or nutrient solution.
  • Week 8: do not use this product during this week of flowering.

Tips for best results

  • Maintain pH and EC/ppm within the range recommended for your growing medium and crop.
  • Use fresh nutrient solution whenever possible and avoid leaving mixed solution stagnant for long periods.
  • Store nutrients in a cool, dark place away from direct sunlight and extreme temperatures.
  • Keep bottles tightly sealed when not in use to reduce air exposure and preserve product quality.
  • Use clean measuring tools and regularly rinse or clean your reservoir, lines, and irrigation equipment.

Common mistakes to avoid

  • Do not mix different nutrients or additives together in concentrated form before adding them to water.
  • Do not exceed the recommended dosage unless you are following a tested, crop-specific feeding plan.
  • Do not skip pH or EC/ppm checks when growing in hydroponic or soilless systems.
  • Do not allow the nutrient solution to freeze or overheat, as this can damage the formulation.
  • Do not ignore the directions on the product label for your specific crop, growth stage, and system type.

Frequently Asked Questions

Why is total nitrogen (N) important for plant growth, and what makes it different from other nutrients?

Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.

Why is water insoluble nitrogen important for plant growth?

Water Insoluble Nitrogen is important because it acts like a slow-release nitrogen reserve that feeds plants steadily over time, which helps maintain consistent green growth and reduces sudden nutrient swings; it’s unique from faster nitrogen forms because it must be broken down in the root zone before plants can use it, so timing and soil conditions matter as much as the total nitrogen amount.

Why is water-soluble nitrogen important for plant growth, and what makes it unique compared to other nitrogen sources?

Water-soluble nitrogen is important because it dissolves in water and becomes available to plants quickly, helping drive fast green growth, strong photosynthesis, and rapid recovery from nitrogen deficiency. It’s unique because it works immediately rather than relying on slow breakdown or conversion, so it delivers faster results—but also requires more careful control to avoid overfeeding, soft growth, or nutrient imbalance.

What does kelp extract actually do for plant growth?

Kelp extract supports plant growth by acting as a biostimulant that helps roots stay active, improves stress tolerance, and encourages steadier new growth without functioning like a heavy fertilizer. It’s unique because it influences plant processes and recovery more than it supplies major nutrients, so it works best as supportive “management help” rather than a direct N-P-K replacement.
