Canna Aqua Flores A & B, 1 L, Set of 2

The CANNA Aqua Flores A & B pair is a complete two-part nutrient system designed to support flowering and fruiting. This setup is rich in compounds that stimulate flowering, with an NPK formula of 4-0-6 in Aqua Flores A. The duo is intended for hydroponic cultivation, providing a balanced nutrient profile that helps plants achieve dense blooms while maintaining stable growth in reusable water systems.
CANNA Substra Flores Hard Water A and B Nutrients, 5 L

These hard-water formulas are crafted for hydroponic systems that use water with elevated mineral content. The Substra Flores hard-water duo is designed to meet all nutritional needs of the plants, delivering balanced elements for steady growth. The packaging emphasizes compatibility with hard-water supplies, helping to stabilize nutrient availability and reduce pH fluctuations in demanding water environments.
Canna Substra Flores AB Hard Water A and B Nutrients, 1 L

This AB bundle provides a compact, hard-water-specific solution for hydroponic systems. The two-part formulation ensures complete nutrient coverage, with attention to elements essential for plant development in challenging water conditions. The 1 L size is convenient for trial runs or smaller setups while preserving the same nutrient balance as larger formulations.
Canna Aqua Flores A Plus B (Flower), 5 L Set

The Aqua Flores A Plus B set provides a flowering-focused nutrient approach. As part of CANNA’s flowering regimen, this 5 L pack aims to optimize bloom formation and overall flower quality, with emphasis on stability and ease of use. This option is suitable for growers seeking a reliable, scalable solution for larger hydroponic or recirculating systems.
Canna Aqua Flores B 5 Liter

As the complementary component to Aqua Flores A, the B part supports balanced nutrient availability and contributes to efficient nutrient uptake. The 5-liter size is designed for ongoing flowering cycles in hydroponic systems, helping ensure consistent bloom development and overall plant vitality in water-based cultivation setups.
Buying Guide: Key Purchase Considerations For Water Canals and Canna Plants
When choosing nutrient systems for hardy water canna and related aquatic plants, consider the following factors to optimize growth and minimize maintenance challenges.
- Water type and hardness: Hard-water formulations are specifically designed to counter mineral interactions that can impact uptake and pH stability. If your tap water is mineral-rich, hard-water blends may improve results.
- Nutrient balance: Flowering-focused mixes emphasize increased phosphorus and potassium to support bloom formation, while base mixes supply essential nitrogen for vegetative growth. Matching the growth stage with the correct product minimizes deficiencies and overfeeding.
- Two-part systems vs. single-bottle blends: Two-part systems can offer more precise control over nutrient availability and pH management, especially in recirculating systems. Single-bottle blends are simpler but may be less adaptable to stage changes.
- Aquatic compatibility: For water lilies and other aquatic ornamentals, ensure products are suitable for hydroponic or pond-based setups. Some formulations are tailored to hydroponics, which can differ from pond soil needs.
- pH stability and buffering: Nutrient solutions with pH-stabilizers help keep the reservoir within the optimal range, reducing plant stress and nutrient lockout. This is particularly important in water-centric environments.
- Volume and scalability: Larger 5 L containers suit established systems with frequent feeding, while smaller 1 L or 2 L packs are ideal for trials or smaller installations. Plan based on growth cycles and reservoir size.
- Ease of use and labeling: Clear instructions and compatibility with your system (recirculating hydroponics, ebb and flow, etc.) reduce the risk of misapplication and improve consistency across grows.
- Safety and compatibility: Always verify that a nutrient line is compatible with your water features, pH management approach, and any other supplements you use to avoid adverse chemical interactions.
