INTENSE PK Ultra 15/19 PK Booster

🌱 INTENSE PK Ultra 15/19 PK Booster — Guide and Product Information

INTENSE PK Ultra 15/19 is a concentrated PK booster formulated to be used alongside a base nutrient during the flowering stage. It is designed for growers who want to strengthen their bloom feeding programme with additional phosphorus and potassium, while keeping application practical and cost-effective thanks to its concentrated formula.

As part of our Nutrients and Boosters range, this product is suited to growers looking to fine-tune flowering nutrition in a wide range of indoor horticultural setups.

🌿 What INTENSE PK Ultra 15/19 is used for

PK boosters are commonly introduced during flowering to supplement a standard feed regime with extra phosphorus and potassium, two key elements associated with bloom development and overall plant performance in the later stages of growth. INTENSE PK Ultra 15/19 is intended to complement, rather than replace, your main nutrient.

• ✔ Supports flowering-stage nutrition
• ✔ Designed for use with a base nutrient
• ✔ Concentrated formula for efficient dosing
• ✔ Suitable for growers refining bloom performance

📦 Available Options and Sizes

INTENSE PK Ultra 15/19 is available in the following sizes:

• ✔ 1L
• ✔ 5L
• ✔ 10L

The smaller size can be a practical choice for trialling the product or for smaller grow spaces, while the 5L and 10L options may suit larger or more frequent feeding schedules.

💧 Flowering support and feeding flexibility

Because INTENSE PK Ultra 15/19 is made to supplement any base nutrient, it can be worked into many feeding programmes where additional bloom support is needed. This makes it a useful option for growers running different substrates or nutrient brands, provided compatibility and dosage are checked before use.

If you are building a broader bloom nutrition plan, you may also wish to explore products such as PLAGRON Terra Bloom Flowering Nutrient or complementary additives like PLAGRON Sugar Royal 5L.

🏡 Suitable applications

INTENSE PK Ultra 15/19 is suitable for indoor horticultural growers who want a concentrated bloom additive to support flowering plants. It is generally most relevant where plants are already established on a complete nutrient programme and require a PK supplement during the appropriate stage of development.

It can be considered for use in hobby and intensive growing environments where careful feed management is part of the routine. As with all concentrated nutrient products, measured application and regular monitoring of the nutrient solution are recommended.

Avoid overfeeding, especially when working with a concentrated additive.

• ✔ Add only to a complete nutrient programme
• ✔ Use during the correct flowering period
• ✔ Measure carefully due to the concentrated formula
