Grotek

Grotek is a Canadian plant nutrition brand with over 25 years of experience formulating hydroponic nutrients and additives. Their range focuses on targeted boosters that layer on top of your existing base feed, addressing specific growth stages and performance goals rather than replacing your main nutrient program.

Early in vegetative growth, Grotek Monster Grow is a high-nitrogen booster built for thick stems and explosive vegetative development. Heading into flower, Grotek Heavy Bud is a science-driven bloom booster targeting flower size, density and final yield. For the critical finish window, Grotek Monster Bloom (0-50-30) is a high-PK flower hardener that transforms light, airy flowers into dense, commercial-grade buds late in the cycle.

Formulated for use in coco, rockwool, NFT, DWC, and soil, Grotek products are trusted by growers across Australia and internationally. Fast shipping across Australia.

Frequently Asked Questions

Can I use Monster Grow, Heavy Bud and Monster Bloom all in the same grow?
Yes. They're designed for different stages, Monster Grow in veg, Heavy Bud through flower, and Monster Bloom in the final PK-heavy finish window, so they work together across the full cycle rather than competing.

Do Grotek additives replace my base nutrient?
No. Grotek boosters are designed to layer on top of your existing base feed, not replace it. Continue your regular base nutrient program and add the relevant Grotek product at the matching stage.

Is Grotek suitable for all growing systems?
Yes. The range is formulated for use in coco, rockwool, NFT, DWC, and soil.

Does Grotek ship fast within Australia?
Yes. All products ship from our Australian warehouse with fast tracked delivery Australia-wide.
