  • Further information

What It Does

It adds extra yield and boosts essential oil production. It is able to provide the perfect ratio of phosphorous to potassium for the flowering period of development.

How It Works

It works as a potent PK booster. Phosphorus is a vital macronutrient for every part. It plays crucial roles in photosynthesis, converting light energy into food, fibre and oil, the metabolism of sugars, energy storage, transfer, cell division, enlargement and the transfer of genetic information. Potassium is able to bolster the transport and manufacture of starches and sugars as well as cell division. The formula not only raises plants' overall resistance it provides the all-important sugars during the flowering.

How To Use Field Marshal Critical Mass

Shake well before use. Use from week 4 of the flowering period until harvest. Apply at recommended dosages.
