Grotek, fertilizers and supplements by growth stage

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.

Dosage and compatibility

Measure in grams and dissolve thoroughly in water. Do not automatically layer it with other high-PK supplements. When using a complete program, adjust the overall concentration to account for all components.

Difference compared with Blossom Blaster

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

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 Vitamax Pro, a molasses and kelp supplement

Grotek Vitamax Pro is a liquid supplement containing organic matter and mineral nutrients. Its ingredients include fermented molasses and kelp. It complements the feeding program during the growth period.

Dosage and frequency

The product guide recommends 1 ml per liter of water, applied weekly during the growth period. Follow the label and the official Grotek feeding chart when combining it with other products.

Vitamax Pro or Vitamax Plus?

These are different products in the range. Choose based on the full product name, and do not automatically transfer the dosage from the other formula.

Role in the program

Vitamax Pro complements the base feed. For concentrated powder feeding during growth, compare Monster Grow Pro. Do not add several products just because they are all intended for growth.

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.

Grotek Blossom Blaster, early flowering supplement

Grotek Blossom Blaster is a highly concentrated powder supplement for early flower formation. It contains phosphorus and potassium and is used as part of a feeding program.

Dosage and timing

The product guide specifies 1 g per 10 L of water, with one repeat after two weeks. It is intended for the initial development of flower buds; follow the label for your specific crop.

Blossom Blaster or Monster Bloom?

Monster Bloom is a separate PK booster with a different formula and application schedule. Do not automatically combine their full doses.

Check the full product name

Blossom Blaster and Blossom Blaster Pro are separate products. This page is for the powder Blossom Blaster. When choosing a package size, follow its label and the official Grotek feeding chart.

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.

Grotek Growth Booster, vegetative growth supplement

Grotek Growth Booster is a water-soluble powdered product containing nitrogen and phosphorus for vegetative growth. It is used to supplement the regular nutrient program according to the plants’ needs.

Dosage

The official guide specifies 1 g per 10 L of water. Dissolve completely and apply according to the label, growth stage, and nutrients already added.

Growth Booster or Monster Grow Pro?

Monster Grow Pro is a different formula. Both products are intended for growth, but they should not automatically be combined at their full dosages. Check what nutritional role the base fertilizer already serves.

Preparing the solution

Measure small quantities with a suitable scale and add products separately to water. To transition to flowering, consider Blossom Blaster according to your chosen schedule.
