Unit price perA concentrated 5-45-19 soluble fertiliser designed to support vigorous bud development as plants make the transition into flowering.
FoxFarm Open Sesame is an early flowering fertiliser formulated to deliver targeted nutrition when plants move from vegetative growth into bloom. Its high-phosphorus 5-45-19 analysis makes it particularly suited to the first sign of buds and the early to middle stages of the flowering cycle.
The soluble powder contains nitrogen, phosphorus and potassium alongside sulphur and chelated iron, manganese and zinc. It dissolves into water for straightforward application through hydroponic reservoirs or conventional soil and soilless feeding programmes.
Open Sesame can be used as a stand-alone flowering feed or at a lower concentration alongside other nutrients, giving growers flexibility when building it into an established feeding programme.
Why choose FoxFarm Open Sesame?
What is FoxFarm Open Sesame used for?
Open Sesame is designed for the point at which plants begin moving out of vegetative growth and into flowering. FoxFarm recommends introducing it from the first sign of buds and using it through the middle weeks of the flowering cycle.
Its 5-45-19 formulation places particular emphasis on phosphorus, while also supplying potassium, nitrogen and selected micronutrients. This makes it a stage-specific fertiliser rather than a general-purpose feed intended for the entire crop cycle.
It can be used in hydroponic and aeroponic systems as well as containers, ordinary garden soil and soilless growing media.
How to use FoxFarm Open Sesame
For stand-alone hydroponic use, add 6g per 4 litres of water in the reservoir. FoxFarm recommends flushing the system every two weeks.
For stand-alone soil use, mix 3 – 6g per 4 litres of water and feed once per week.
When combining Open Sesame with other nutrients, use 1.5 – 3g per 4 litres of water for hydroponic or soil applications. When used in soil alongside other nutrients, feed once per week.
Always add Open Sesame to the final volume of fresh water and mix thoroughly. Do not mix concentrated soluble fertilisers together while they are still dry. Open Sesame is intended for root-zone feeding and should not be used as a foliar spray.
