OG Rapid Flower Hardener 1L – High-PK Bloom Booster for Denser Flower Development

OG Rapid Flower Hardener has been specifically designed to activate flower production and deliver a significant increase in flower mass. This proprietary formulation delivers results through technology allowing superior plant uptake.

Results can be seen almost immediately with a speedy onset of rapid flowering. OG Rapid Flower Hardener then produces expanding flower mass with daily increases in weight throughout the remainder of the flowering cycle.

OG Rapid Flower Hardener can force a rapid onset of flowering when used in week one of the flowering cycle, or increase weight and density when used in weeks 6–7 of the flowering cycle — or both.

How to Use

Recirculating and Run to Waste Systems: Once plants have grown to your desired height, apply OG Rapid Flower Hardener for 7 days at a rate of 1–2ml per litre of nutrient solution. If making up a new batch during the 7-day period, re-dose accordingly. Flush your system with fresh water after the 7-day period and return to your regular nutrient feeding programme.

To increase flower density further, repeat the above application in weeks 6 and 7 of your flowering cycle. These longer applications at lower dosages provide a more uniform effect across the entire plant. This late application can also be used to increase final flower weight even if the product was not used to initiate flowering initially.

Soil and Sunshine Mix: Once plants have reached your desired height, apply with your current fertiliser on feed days at 1–2ml per litre of nutrient solution. Flush growing media with fresh water after 7 days of use.

Coco: For hand-fed coco systems, follow the soil/sunshine mix directions. For recirculating or run-to-waste coco systems, follow the hydroponic instructions above.

Tip: The manufacturer recommends 2ml per litre, however 1ml per litre is often sufficient given the product’s high concentration.
