When it comes to growing cannabis—or any fruiting or flowering plant—the right nutrient balance can make all the difference. One product that’s been gaining attention among cultivators is Tundra Hybrid Fertilizer, which is designed specifically to enhance fruit and flower development.

In this article, we’ll break down what makes Tundra unique, how it performs in cannabis grows, and whether it’s worth adding to your nutrient lineup.

What Is Tundra Hybrid Fertilizer?

Tundra Hybrid Fertilizer is a premium nutrient formula developed by Impello Biosciences and is designed to support the transition and flowering stages of plant growth. It’s marketed as a balanced blend of macro and micronutrients tailored for heavy bloom production—particularly in fruiting and flowering species such as tomatoes, peppers, and of course, cannabis.

Unlike many standard bloom boosters that only focus on phosphorus and potassium, Tundra Hybrid uses a hybrid nutrient profile that combines both organic and synthetic elements. This approach gives plants fast nutrient uptake while maintaining long-term soil health, making it a flexible choice for soil, coco, or hydroponic setups.

Ingredients:

According to the SDS on the Impello Biosciences website, the active constituents are:

Potassium <10% ; Phosphorous <8%; , Polypeptides <1%;Kelp extract <5%; Fulvic acid <2%; water (bal.)

Performance in Cannabis Cultivation

In cannabis, the flowering phase is when the buds begin to develop. During this time, plants demand higher levels of phosphorus and potassium to form dense buds, while still needing enough nitrogen and trace elements to maintain healthy foliage.

Growers who’ve used Tundra Hybrid report noticeable increases in flower density, improved terpene production, as well as a vibrant color in their plants.

Buds tend to mature with a tighter structure, and the overall yield benefits from the nutrient balance.

Ease of Use

Tundra Hybrid Fertilizer is easy to mix and apply. The product dissolves quickly in water without leaving residue, which helps prevent clogging in drip systems or sprayers. Most growers use it as part of a two-part feeding schedule—starting with a vegetative formula, then switching to Tundra Hybrid during flowering.

Application Rates

The manufacturer provides clear dosage instructions, depending on the growth stage and plant size.

Adjusting this amount based on strain and environment usually yields the best results.

Containers:

Lite: 5mL / Gallon
Recommended: 10mL / Gallon
Heavy: 20mL / Gallon

Field:

Lite: 1 gallon / acre
Recommended: 2 gallons / acre
Heavy: 4 gallons / acre

Storage

According to the manufacturer, Tundra should be kept in a cool, dry place, with the container sealed when not in use. Avoid exposing it to excessive heat or humidity, as these conditions can affect product quality.

When properly stored, Tundra should remain shelf-stable for up to 24 months.

Verdict

Overall, Tundra Hybrid Fertilizer for Fruit & Flower Development is a high-quality, well-balanced nutrient that delivers impressive results in the flowering phase. It’s perfect for growers who want strong, aromatic, and high-yielding cannabis plants without overcomplicating their feeding schedule.

Its hybrid formulation bridges the gap between organic and synthetic nutrients, giving plants fast access to what they need while maintaining root and soil vitality. While it’s a bit pricier than many basic bloom boosters, the payoff in flower quality and yield makes it a smart investment.
