Quick Boost Pro-XL is a flowering stimulator designed to boost the development of dense and heavy buds in the most critical phase of cannabis cultivation.
It provides highly assimilable phosphorus and potassium to achieve explosive flowering from the first weeks of the 12/12 photoperiod.

Quick Boost Pro-XL is a specialized fertilizer belonging to the Pro XL Fertilizers line, formulated to enhance the fattening and formation of flowers in marijuana crops.
Its action is based on a synergy between phosphorus and potassium, two essential macronutrients to ensure abundant, compact, and resilient floral development.
Phosphorus is directly involved in the formation of roots and flowers, improving energy transfer in the plant, while potassium promotes protein synthesis, enzymatic functioning, and resistance to pests and diseases.
The use of Quick Boost Pro-XL is recommended from the third week of life, just before switching to 12/12 hours, a key moment to prepare the plant for an intense flowering cycle.
It is a fully water-soluble product and compatible with any type of crop, including soil, coco, hydroponics, NFT, and aeroponics. Thanks to its versatility, it is ideal for professional crops with automatic irrigation systems. Its effect is visible from the first applications, promoting the formation of flowering shoots with shorter internodes, and facilitating the subsequent fattening phase with other additives such as Bloom XXL or Flora Exploder.
The recommended dosage is 0.5 ml per liter of irrigation water.
It should be applied from the third week of life of the plants, just before the change of photoperiod, and then once a week during the fourth and fifth week of the crop (which correspond to the first and second week of flowering).
It can be mixed without problem with the basic fertilizers of the Pro-XL range or other compatible brands.
This combination allows for rapid and effective assimilation of nutrients, tailored to the needs of cannabis cultivation in its most demanding phase.
Quick Boost Pro-XL is a powerful flowering stimulator created by the Pro XL brand to maximize flower production in marijuana crops. Its use is positioned at a strategic stage of plant development: right at the beginning of flowering.
It is designed to provide a solid reserve of phosphorus and potassium, ensuring that plants do not suffer deficiencies during the most demanding phase of the cycle.
The effectiveness of the product lies in its fully soluble and easily absorbable formula, making it a key ally for demanding growers seeking more abundant, homogeneous, and higher-yielding harvests.
