REGENiGROW™ Biostimulant (2 gal)

Not a fertilizer. A living soil amendment that wakes up the biology your garden already has.

Two gallons at bundle pricing — for the gardener (or grower) who's serious about it. Right for the gardener treating soil regeneration as a project instead of an experiment, landscapers running several properties, market growers with real production beds, and small farms making the conventional-to-biological transition.

What it is

REGENiGROW™ is a shelf-stable liquid concentrate made from microalgae (cyanobacteria) we cultivate in our EPL closed-loop biorefineries. We grow the algae in sunlit ponds, digest them anaerobically, and stabilize the result into the liquid in this bottle. What's inside is a complete soil-biology feedstock: amino acids and plant protein, the full B-vitamin family, humic substances that hold nutrients in the root zone, and microfine biochar that gives microbes a permanent home. It's not a fertilizer that the plant takes up directly — it's the food and shelter that lets your soil's own biology deliver nutrition to the plant the way nature does it.

What it does in your garden

• Wakes up dormant soil biology. The amino acids and B-vitamins feed soil microbes that have been starved on depleted ground, sometimes for years. Within days, sparse populations bloom into thriving underground communities.
• Unlocks nutrients your soil was already holding. Phosphorus that was chemically locked to calcium, iron, or aluminum becomes available again. Plants pull several times more nitrogen and phosphorus out of the same soil.
• Rebuilds the mycorrhizal network. The fungal threads that move nutrients between plant roots reconnect. Potassium uptake improves, especially in clay-heavy soils where the network was broken.
• Stabilizes everything for the long term. The microfine biochar holds onto water, nutrients, and microbes year over year, so the biology you wake up this season builds on itself the next.

What our customers see

Across multiple field trials — different farms, different soils, different crops — REGENiGROW™ has more than doubled yields, produced a 17× increase in living soil microbiome measured by an independent lab, and helped plants pull 4–5× more nitrogen and phosphorus from the same ground. The strongest documented case is a 2021 trial at the Crater Road farm in Polipoli, Maui, on weathered volcanic soil — one of the most biologically depleted soil types in agriculture. The full agronomic report and supporting science papers are at regenitech.com/products.

Where to use it

Vegetable gardens. Raised beds. Container plantings. Cut-flower beds. Established landscapes. Small farms. Indoor plants. Lawns and turf. Anywhere you want to rebuild soil biology rather than just feed plants. Two gallons covers two main beds, a small farm pilot, or several properties for a landscaper across a full season.

How to apply

Usage Instructions

Mixing: Use one half cup of REGENiGROW™ per gallon of water.

This is the dose that produced the headline yield jumps in our field trials. Apply two ways:

Soil drench (recommended for the bigger effect). Pour the mixture at the base of plants. Feeds the soil biology and the plants together.

Foliar spray (for a fast boost). Spray the mixture directly on the leaves. Plants take up the nutrients within hours — great for stressed plants, recovering crops, or topping up minerals mid-season.

For best results, use both. And follow the dose — more isn't better. In our trials, doubling the recommended dose actually brought yields back down. Think of REGENiGROW™ as a meal for the soil, not a fertilizer to load up.

Specs

• No live non-native organisms — cleared for use in biosecurity-strict regions including Hawaii, Australia, and New Zealand
• Multi-year shelf life under standard storage conditions
• Made in USA

Better with the full Soil Battery

Think of REGENiCHARGE™ as the soil battery — a permanent carbon scaffold you install once. REGENiGROW™ is the charge that brings it to life. Install REGENiCHARGE™ once at bed prep; recharge with REGENiGROW™ each season. Shop the bundle →

Buying in larger volumes?

If you're a market grower, larger farm, landscaper, retailer, or planning bulk applications, drop us a note at regenitech.com/contact-us. We'll set up the right arrangement — volume pricing, scheduled deliveries, or partnership options through our Distribution Node network. Learn more about the network at regenitech.com/network.

Outside the US?

We currently ship within the United States only. International retail shipping rarely works economically — sending a single quart to New Zealand would cost more than the product. If you're outside the US and want REGENiGROW™ available where you are, the right path is usually to become a Distribution Node in your country. We supply product in bulk; you handle local product registration, import licensing, and regional sales. The program is structured to be as turnkey as we can make it.

Common questions

Is this a fertilizer? No. Conventional fertilizers add nutrients the plant takes up directly, often inefficiently — nitrogen volatilizes within weeks, phosphorus locks up chemically, potassium gets blocked without a healthy mycorrhizal network. REGENiGROW™ takes a different path. It feeds the soil biology that delivers nutrition to plants the way nature does it. Most growers find they need less synthetic fertilizer over time, not more.

Does it have live microbes in it? No, and that's deliberate. The product is stabilized after digestion, so there are no live organisms. What's in the bottle is the food, vitamins, and minerals your soil's own native microbiome needs to wake up. That design is why the product has a multi-year shelf life, why it's OMRI Listed, and why it's safe for use in biosecurity-strict regions where live-inoculant products are restricted.

How often do I need to apply? Most growers apply every 2–4 weeks during the active growing season, alternating between soil drench and foliar spray. For established beds with REGENiCHARGE™ already installed, a monthly recharge through the season is usually enough.

Can I use it on lawns? Yes. Apply as a soil drench mixed into irrigation water, or with a hose-end sprayer. REGENiGROW™ is especially effective on tired or compacted turf where the soil biology is depleted.

Is it safe around pets, kids, and edible crops? Yes. No synthetic pesticides, herbicides, or chemical fertilizers. OMRI Listed for use on certified-organic edible crops. Standard handling care: wash hands after use.

Can I use it alongside my regular fertilizer? Yes — and you'll probably find you need less of it. REGENiGROW™ rebuilds the biological system that makes any fertilizer effective in the first place, so the conventional inputs you do use start working harder.

Does it work on indoor plants? Yes. Dilute at the same half-cup-per-gallon rate for soil application, or use as a light foliar spray. A quart-sized bottle goes a long way for indoor gardens.
