Peakboost is an ultra-concentrated, fast acting phosphorus booster and flower site initiator designed for use in early to mid-flower. This Potassium free formula is extremely bioavailable making it the perfect shaping tool for small and large scale cultivators.

How To Use:

Add PEAKBOOST to your reservoir every feeding from the first week to the fourth week of the flowering stage. It is okay to extend or shorten the usage of PEAKBOOST based upon the total flowering time of your specific plant or by the preferences of each individual cultivar.

When mixing with any calcium supplements (like MASSBOOST or MINERAL-CALMAG), be sure to allow one to mix in the solution before adding the other to minimise possible lockout.
