METROP Colosal PK 500g

Product detailed description

Metrop Colosal PK is a water-soluble flowering PK booster in powder form (NPK 0-52-34). It is for growers who want to supply concentrated phosphorus and potassium during the flowering stage and support the formation, swelling and weight of flowers and fruits - in soil, coco and hydroponics.

What Metrop Colosal PK is for

Colosal PK is a pure dose of phosphorus (P2O5 52 %) and potassium (K2O 34 %) without nitrogen - exactly what the plant needs at the peak of flowering, when it is swelling buds and fruits. Phosphorus drives the formation and development of flowers, potassium their swelling, weight and ripening. The powder dissolves easily and the nutrients are immediately available, so the effect on plants is fast. At the same time, it helps regulate water balance and improves the uptake of other nutrients.

Dosage and use

Apply Colosal PK at the first signs of flowering and continue with every watering throughout the flowering period - the dose is 2.5 g per 10 l of water. Stop using it 1-2 weeks before harvest so that the plant can finish on plain water. As with any concentrated PK booster, monitor EC and do not overdo it; more phosphorus does not mean more flowers.

What to combine Colosal PK with

Colosal PK is a PK peak above the basic flowering base Metrop MR2 - MR2 provides complete flowering nutrition, while Colosal PK boosts it at the peak with extra phosphorus and potassium. It also works well with the amino stimulant Metrop AminoXtrem Bloom. However, do not combine two PK boosters at once and monitor EC.

Frequently asked questions

When should Colosal PK be applied and when should it be stopped?

Start at the first signs of flowering and add it with every watering throughout the flowering period at a dose of 2.5 g per 10 l of water. Stop using it about 1-2 weeks before harvest so that the plant can finish on plain water or a flush. This supports the formation and swelling of flowers at the right time.

What is the difference between Colosal PK and MR2?

MR2 is a complete flowering fertiliser with all macro and micronutrients that form the basis of flowering nutrition. Colosal PK is a pure PK booster (0-52-34) without nitrogen, added on top at the peak of flowering for extra phosphorus and potassium. They are used together, not one instead of the other.

Can I use Colosal PK in hydroponics as well as in soil?

Yes. Colosal PK is a water-soluble powder and works in soil, coco and hydroponics. Dissolve 2.5 g in 10 l of water, mix well and check the EC of the solution. In hydroponics, add it to the reservoir and watch how the plant responds so you do not overfeed it at the peak of flowering.
