Unit price

Grotek Monster Bloom, PK flowering booster

Grotek Monster Bloom is a concentrated powder booster with phosphorus and potassium for flower development and ripening. The formula is labeled NPK 0-50-30 and is used as a supplement to a chosen feeding program.

When should it be applied?

Begin when flower buds form. The manufacturer recommends discontinuing use 1 to 2 weeks before harvest. Follow the label on the specific package and the schedule for your crop.

Blossom Blaster is intended for early flower formation and has a different application. The name Monster Bloom does not refer to the liquid version, Monster Bloom Liquid.

Grotek Monster Grow Pro, growth supplement

From €11,25

Unit price

Grotek Monster Grow Pro, growth supplement

Grotek Monster Grow Pro is a water-soluble powder for vegetative development, roots and plant structure. It combines mineral and organic nutrients.

How to use

Apply during the vegetative period according to the label and chosen feeding schedule. Dissolve the measured amount in water. When combining it with other fertilizers, account for the nutrients already applied.

How to choose the dosage

The dosage for standalone use may differ from the amount used in a combined feeding program. Follow the specific label and the official Grotek feeding chart; do not add together the full amounts of several similar products.

Monster Grow Pro or Growth Booster?

Growth Booster is a separate formula containing nitrogen and phosphorus. A similar purpose does not mean the composition or dosage is the same. For the next flowering phase, consider Monster Bloom according to the feeding program.

Grotek Final Flush, salt-flushing solution

From €9,97

Unit price

Grotek Final Flush, salt-flushing solution

Grotek Final Flush is a solution for flushing accumulated salts from the root zone. It is used for substrate maintenance and during the intended final phase, according to the feeding program.

Dosage

The official European distributor recommends 10 ml per 5 L of water, equivalent to 2 ml/L. Check the instructions for the specific variant before use.

Soil, coco and hydroponic systems

For pots, follow the flushing instructions and allow excess solution to drain freely. For a hydroponic reservoir, follow the separate instructions for use, draining and resuming feeding.

Variants and purpose

Choose an available option from the product selection. Final Flush is a flushing product, not a flowering PK booster like Monster Bloom. Do not increase the dose to add flavor.

Unit price

Grotek Carbo Max 700 g, carbohydrate supplement

Grotek Carbo Max 700 g is a powdered carbohydrate supplement for feeding programs during flowering. It is used dissolved in water or nutrient solution.

Dissolving and dosage

The official guide specifies 100 g per 380 L of water or nutrient solution, approximately 0.26 g/L. Measure with a suitable scale, dissolve thoroughly, and follow the label for your specific program.

When should it be applied?

The manufacturer describes using it during flowering alongside feeding or when changing the nutrient solution. Adjust this to suit your system's operating schedule.

Does it replace fertilizer?

Carbo Max supplements feeding. It does not replace base macronutrients and is not dosed like Monster Bloom. For a supplement aimed at mid to late flowering, compare Heavy Bud Pro.

Grotek Heavy Bud Pro, ripening supplement

From €36,81

Unit price

Grotek Heavy Bud Pro, ripening supplement

Grotek Heavy Bud Pro is a liquid supplement for the middle and late stages of flowering, when flowers and fruits are developing. It complements the regular nutrient program.

Dosage and number of applications

The official guide specifies 2 ml per liter of water and 3 to 4 applications during the ripening phase. This does not mean it should automatically be applied at every watering. Adjust the timing to the crop and the label.

Difference from early-stage supplements

Blossom Blaster plays a role in early flower formation. Heavy Bud Pro is intended for a later stage of development, so the products are not interchangeable just because they are both for “flowering.”

Combining products

Account for all components of the solution. If you are interested in a carbohydrate supplement, compare Carbo Max, without assuming their dosages are interchangeable.
