Know before you buy
Open Sesame is specifically formulated for the early flowering and ripening stages. You should introduce it when you are ready to initiate blooming or see the first signs of bud development.
Yes, Open Sesame is fully water-soluble and designed to be compatible with hydroponic and aeroponic systems. Its formula is engineered to minimize salt and residue buildup, making it safe for recirculating water setups.
Open Sesame is pH-balanced to support optimal nutrient uptake. However, you should always check the pH of your final water mixture after adding any fertilizer to ensure it remains within the ideal range for your specific plants.
It is highly versatile and can be used on flowers, vegetables, trees, shrubs, and houseplants. Because it is a high-phosphorus bloom booster, it is best reserved for plants that are currently in their flowering or fruiting phase.
Because it is a quick-release formula, it provides immediate nutrition to the plant. It is best used as a targeted supplement during the early flowering weeks; follow the specific dilution instructions on the packaging to avoid over-fertilizing.
