FoxFarm Open Sesame

Early Flowering Fertiliser for Strong Growth

FoxFarm Open Sesame is a soluble flowering fertiliser designed to support plants during the early stages of bloom. Formulated with a strong phosphorus and potassium profile, it helps plants transition into flowering and begin forming bud sites across the canopy.

Used during the first phase of flowering, Open Sesame provides nutrients that plants require when shifting from vegetative growth into bloom.

It dissolves easily in water and can be used in hydroponics, coco coir, and soil systems as part of a structured flowering nutrient programme.

Please note: these items are purchased to order so extended lead times will apply.

Key Benefits

• Supports early flower development; encourages plants to begin forming bud sites
• High phosphorus and potassium formula; designed for the start of the flowering stage
• Water-soluble powder; dissolves easily into nutrient solutions
• Suitable for multiple growing systems; works in hydroponics, coco coir, and soil

Why You Need FoxFarm Open Sesame

The first stage of flowering is when plants begin forming the bud sites that will later develop into full flowers. During this period, plants require higher levels of phosphorus and potassium to support the transition into bloom.

Open Sesame is designed specifically for this early flowering window, supplying the nutrients needed as plants begin producing flowers. When used at the correct stage, it helps establish a strong flowering structure before switching to later-stage bloom nutrients.

How to Use FoxFarm Open Sesame

1. Start early in flowering: Begin using Open Sesame during the first stage of the bloom cycle.
2. Mix into your feed: Dissolve in water and add to your nutrient solution.
3. Recommended dosage: Use 0.25–0.5 teaspoons per US gallon (approximately 0.3–0.6g per litre).
4. Use for early bloom period: Apply during the early flowering phase before switching to later-stage bloom boosters.

Top Tip: Open Sesame is designed for the early bloom stage. After this phase, growers often switch to mid- and late-flowering boosters to support continued bud development.
