By Far the best plant maturer we have! 

Perhaps the most noticeable implementation of the Third Pillar of Aptus Philosophy: Mineral Antagonism. Finaleboost moves the vast majority of potassium used during the bloom cycle solely into one product. With this formulation, Aptus has allowed for absolute control of heightened potassium application throughout the specific phases of a plant’s growth cycle.

On top of allowing for specific potassium application in consideration of your plant genetics, stage in the growth cycle, or desired flower set behavior, the potassium in Aptus Finaleboost is chelated into an organo-mineral product.

With the addition of L-amino acids, the potassium has eyes only for the plants’ roots and has a much smaller chance of being affected by outside factors.

The specific application of chelated potassium allows for optimal health by removing the negative antagonistic effects of cheap bulk products containing high amounts of both potassium and phosphorous. With Aptus Finaleboost, you will see the difference in your final harvest by having optimal chelated potassium with the elements usually antagonised away including: nitrogen, calcium and magnesium. It’s no wonder some manufacturers want you to load up on Cal-Mag in bloom.
