Fox Farm Open Sesame

Set more bud sites and stronger blooms in early flower

Fox Farm Open Sesame is a high-phosphorus soluble bloom fertiliser with an NPK of 5-45-19, formulated for the early weeks of flowering when a plant is establishing the bud sites that fill out later. It is a fast-dissolving powder, the first stage in Fox Farm's early-bloom lineup, used on its own or worked into an existing feed schedule.

Key Benefits

• High-phosphorus NPK 5-45-19 aimed squarely at early bloom and bud-site development.
• Supports vigorous blooming with stronger, more numerous flowering sites.
• Fast-dissolving soluble powder suited to hydroponic reservoirs or soil and coco watering.
• Flexible dosing for standalone use or alongside an existing nutrient programme.
• Encourages sturdier stems to carry the extra flower load through bulking.

Struggling to get strong bud development early in flower?

The switch into flower places heavy demand on phosphorus just as the plant is setting the bud sites that will later fill out, and a base feed alone does not always cover that spike. Open Sesame is timed for that early window to fuel vigorous flowering structure from the start.

How to Use

• When to start: begin around the 5th to 6th week of the plant's life, at the transition into bloom.
• Hydroponics, standalone: around 1.6g per litre, flushing the system every two weeks.
• Soil and coco, standalone: around 0.8-1.6g per litre once a week.
• Alongside other nutrients: cut back to around 0.4-0.8g per litre.
• Root-zone only: designed for feeding, not foliar spraying; adjust to plant response.
