🌱 CANNA Mono P 20% Phosphor 1 Litre — Guide and Product Information
Product Overview
CANNA Mono P 20% Phosphor is a liquid mononutrient formulated to provide plants with phosphorus, one of the key elements involved in healthy development and productive flowering. As part of the CANNA mononutrient range, it is made from high-quality ingredients and is designed to integrate with wider feeding programmes where targeted nutrient support is needed.
This product is especially useful when plants require additional phosphorus during demanding stages of growth or when you need to respond to a phosphorus shortfall in a controlled and measured way.
Why Phosphorus Matters
Phosphorus plays a major role in the plant’s energy system and is closely linked to bloom development. CANNA states that its liquid phosphorus can directly be absorbed by the plant due to its soluble form, making it a practical option for growers looking to support flowering performance and overall nutrient balance.
- ✔ Supports the plant during bloom development
- ✔ Helps maintain balanced phosphorus availability
- ✔ Useful when correcting phosphorus deficiency
- ✔ Liquid format is easily soluble and practical to mix
Features and Compatibility
CANNA Mononutrients are intended to give growers more control over specific elements within a feed schedule. CANNA Mono P 20% Phosphor is 100% nutrient compatible within the CANNA range and is best used with CANNA base nutrients where appropriate.

Suitable Applications
This product is suited to growers who want to fine-tune plant nutrition with a dedicated phosphorus source. It can be a practical addition during flowering phases or where plants show signs associated with low phosphorus availability. As with any concentrated nutrient, careful dosing and observation are recommended.
Growers using structured feeding schedules may also wish to explore related products such as PLAGRON Terra Bloom Flowering Nutrient or PLAGRON Power Roots Root Stimulator depending on the wider needs of the crop and growing stage.
Related Products and Growing Advice
For growers refining their feeding strategy, additional supplements such as Monkey Magic Plant Booster may be useful as part of a broader nutrition plan.

Setup and Usage Tips
Always add mononutrients carefully and only in amounts appropriate for your plants and growing system. Start by checking your existing nutrient schedule and avoid over-correcting if you suspect a deficiency. Mix thoroughly into water and monitor plant response over time rather than making large adjustments all at once.
Maintaining a stable grow room environment can also help with nutrient uptake. Good airflow, lighting and irrigation practice all contribute to more consistent performance.
