Supercharge your harvest with Canna PK 13/14. Get bigger, denser buds packed with resin and flavor. Fast, simple, and built to work in any grow setup. Just add during the flowering stage and watch yields explode.

Canna PK 13/14 is a high-quality phosphorus and potassium supplement. It helps plants finish flowering strongly by building dense, resinous buds. After drying, this results in compact, potent flowers.

During flowering, cannabis plants need a lot of phosphorus (P) and potassium (K). Using PK 13/14 ensures your plants get enough of these nutrients for maximum bud development. It improves both the quantity and quality of your harvest.

Canna PK 13/14 contains 13% phosphorus and 14% potassium, the purest forms of these nutrients. Phosphorus boosts cell formation and energy transfer, while potassium increases sugar production, making flowers bigger and more fragrant.

Apply PK 13/14 three to four weeks before harvest. Use it at a maximum concentration of 1.5 ml per 1 liter of water.

Always check EC (maximum 1.8 mS/cm) and pH (below 7.0) after adding it to avoid overdose or nutrient lockout. Follow the CANNA feed chart so you don't over-saturate your cannabis plants. Overdose can burn and stress the plant. Avoid high pH levels above 7.0, as this can lead to saturation and irreversible salt buildup, harming your plants.

Absolutely. PK 13/14 works well in soil, recirculating systems, coco, and run-to-waste setups, both indoors and outdoors. It’s your go-to product for boosting flowering success on any grow medium.

Yes, PK 13/14 can be combined with other CANNA products and CANNA BOOST for enhanced flowering. Never use PK 13/14 in pure form, as it can destabilize your nutrients and cause deposits. Follow instructions, make sure you don't overdose.
