Professor's Nutrients - Grow Fast - Premium Vegetative Accelerator
Professor's Nutrients Grow Fast is a dynamic growth booster scientifically engineered to shorten the vegetative cycle by dramatically accelerating plant growth. Formulated with a specialised blend of multiple nitrogen variations, Grow Fast ensures rapid, effortless root absorption for an almost instant plant response. This targeted nutrient surge provides the vital energy needed to build a stronger, bulkier plant frame with thick stems and robust lateral branches.
By maximising vegetative vigour, Grow Fast effectively prepares your plants to support massive, heavy flower yields before they transition into the bloom phase. It is the definitive additive for commercial and hobbyist growers looking to minimise turnaround times and maximise canopy potential. A well-grown vegetative plant is the foundation of a high-yielding harvest, and Grow Fast ensures that foundation is built as quickly and strongly as possible.
Best For: Shortening the vegetative growth phase, accelerating leaf and stem development, building robust plant structures to support heavy yields, and priming crops for a highly productive flowering stage.
Key Features:
- Multi-Form Nitrogen Blend: Combines multiple fast-acting nitrogen sources to guarantee immediate uptake, preventing vegetative stalling and driving rapid green growth.
- Accelerated Vegetative Cycle: Drastically cuts down the time required in the "veg" phase, allowing for faster crop rotations and more harvests per year.
- Bulkier Plant Framework: Promotes tight nodal spacing, thick woody stalks, and robust branches capable of bearing maximum weight during the flowering cycle.
- Transition Readiness: Optimises internal plant processes and carbohydrate storage, ensuring a smooth, shock-free transition into the bloom phase.
- Highly Concentrated & Versatile: Dilutes perfectly in water without falling out of solution, making it ideal for both automated hydroponic systems and hand-watered soil gardens.

- Application Window: Use throughout the vegetative cycle. Discontinue use immediately prior to the start of the flowering/bloom stage to avoid excessive nitrogen levels during bud development.
Usage Tip: To maximise the efficiency of Grow Fast, ensure your grow room humidity (VPD) is kept within the ideal vegetative range. This allows the plant to transpire effectively, pulling the multi-form nitrogen blend through the vascular system at an accelerated rate for even faster visible results.

Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.

Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:

- Seeds cannot be shipped to Western Australia (WA).
Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
