Professor's Nutrients - Flower Boost - Premium Liquid PK Flower Enhancer
Professor’s Flower Boost is a high-grade, concentrated liquid Phosphorus (P) and Potassium (K) flowering additive scientifically engineered to initiate early budding and accelerate nodal development. Formulated to meet the extreme nutritional demands of crops entering their reproductive cycle, Flower Boost works by activating key flowering enzyme production within the plant. It provides the essential mineral foundation required to transform vegetative energy into explosive floral growth.
By providing a perfectly balanced ratio of highly bioavailable PK, this premium liquid booster aids in crucial cellular energy transfer and the storage of complex carbohydrates. The result is a dramatic increase in flower site initiation, faster bud onset, and ultimately, larger, heavier, and far more robust blooms of exceptional quality. Whether you are a commercial producer or a hobbyist, Flower Boost ensures your plants have the fuel necessary to support a heavy, high-density canopy.
Best For: Initiating early flowering and tight nodal stacking, activating bloom-stage enzyme production, enhancing carbohydrate energy transfer, and driving heavy final bloom weights.
Key Features:
- Flowering Enzyme Activation: Triggers the plant's natural hormonal and enzymatic pathways, forcing a rapid transition from vegetative growth to explosive flower development.
- Optimised PK Ratio: Delivers high-purity Phosphorus and Potassium in a highly soluble liquid form, ensuring instant root absorption and rapid cellular distribution.
- Carbohydrate & Energy Transfer: Supports the plant's internal ATP (energy) pathways, allowing efficient translocation of sugars and starches directly to developing flower clusters.
- Faster Bud Onset: Minimises transition lag by encouraging tight internodal spacing and the immediate formation of abundant, healthy budding sites.
- Universal Media Performance: Formulated to remain completely stable in solution, preventing line blockages, emitter clogs, or pH instability in both soil and hydroponic setups.
Specifications:
| Feature | Details |
|---|---|
| Brand | Professor's Nutrients |
| Product Type | Concentrated Liquid PK Bloom Booster & Enzyme Activator |
| Application Phase | Active Flowering Cycle / Bloom Stage |
| Compatible Media | Hydroponics, Coco Coir, Rockwool, Clay Pebbles, and Soil |
| Available Sizes | 1 Litre, 5 Litre, 10 Litre, and 20 Litre |
Directions for Use & Application Rates:
- Hydroponics & Soil-less Media: Add 2ml of Flower Boost per 1 Litre of water or primary nutrient solution.
- Soil-Based Gardening: Add 1.5ml of Flower Boost per 1 Litre of water or nutrient solution.
- Usage Timing: Apply continuously during the active flowering stage alongside your base nutrients to support ongoing flower development and maximum final weight.
Usage Tip: To maximise the effect of Flower Boost, start application as soon as you switch your light cycle to 12/12 (or at the first sign of pre-flowers in outdoor gardens). This ensures the plant has an immediate surplus of Phosphorus and Potassium to support the "stretch" phase and the formation of initial flower sites.

Oversized Item Delivery Options
Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.

Important Notes:
- Shipping costs vary by location and method
- Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.
Business Delivery:
- Business delivery is available for commercial customers only
- If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
- If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order
- Business delivery customers must provide a valid business address and contact information
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

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.
Biosecurity & Interstate Shipping Restrictions
Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:
- Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
- 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.
