Fox Farm Open Sesame is a fast-acting early flowering booster designed to help plants transition from veg to bloom quickly while increasing the number of bud sites across your canopy.
Formulated as a high phosphorus and potassium bloom booster powder, it delivers exactly what plants need during the first stage of flowering – helping them commit to bloom and start producing flower sites sooner.
If you want a stronger start to flowering and better yield potential later on, Open Sesame is built for that critical early window.
Please note: This item is purchased to order and may have extended lead times.
The first week of flowering is one of the most important stages in the entire grow cycle. This is when your plant determines how many bud sites it will support.
If this stage is weak or delayed, your final yield can suffer.
Fox Farm Open Sesame is specifically designed for this moment – providing the nutrients needed to push plants into bloom quickly and maximise early flower development.
Start using Open Sesame at the beginning of the flowering stage.
Dosage: 0.3 – 0.6g per litre (approx. 0.25–0.5 tsp per US gallon)
Mix into your nutrient solution and apply during the early flowering phase only. After this stage, switch to a mid- or late-flowering booster.
Use Open Sesame strictly during early bloom – switching to a mid/late flowering booster at the right time is key to maximising overall yield.
