Aptus Peakboost
Best bloom booster for growers seeking larger, higher-quality harvests.
Aptus Peakboost is a specialized liquid nutrient concentrate designed to enhance plant flowering and bulking. It strategically delivers high levels of plant-available phosphorus, separated from potassium to prevent nutrient antagonism. This ensures optimal uptake of essential micronutrients like zinc, iron, and copper, which are often hindered by standard fertilizers. Peakboost is ideal for use during weeks 2-6 of the flowering cycle to improve final harvest quality and yield, and can be lightly applied during vegetative growth to support overall plant health.

Know before you buy
Peakboost is designed to be used during weeks 2 through 6 of the flowering cycle. This timing ensures your plants receive the necessary phosphorus boost during their most critical bulking phase.
Yes, you can apply it lightly during the vegetative stage to support overall plant health. Use a diluted rate of 1 ml per gallon for vegetative growth.
Separating phosphorus from potassium prevents nutrient antagonism, which is a common issue where one nutrient blocks the uptake of another. This separation ensures your plants can effectively absorb essential micronutrients like zinc, iron, and copper.
While it is specifically formulated to work seamlessly within Aptus feeding programs, it is a mineral-based nutrient that can be integrated into most standard feeding schedules. Always monitor your total EC levels when mixing products from different brands.
Peakboost is a versatile liquid concentrate that can be applied either as a soil drench or a foliar spray. Choose the method that best fits your current irrigation or maintenance routine.
No, Aptus Peakboost is a mineral-based fertilizer and is not organic certified. It is designed for growers who prioritize precise, quick-release nutrient delivery for maximum yield.
