Our revolutionary complete blend of Macro, and Micronutrients, Vitamins B, C, E, and our science base resin enhancer are a first of its kind in the cannabis industry.

It's exceedingly high purity ingredients imported from all over the world provide quality the industry so desperately needs. This amazing product has been in development for 10 years anticipating the world of legal cannabis. Our team is now strategically ready to launch our powdered line of Full Spectrum A&B to the world.

Ease of use and the correct proportion of nutrients makes this formula unlike any in the cannabis market today.

Most base NPK products are exactly that, NPK. At Full Spectrum we recognize the expense of growing cannabis with the elevated costs of quality plant additives and bio stimulants. Our plant science department has created a new formula that has added a high grade resin enhancer with our quattro pro B, C and E stress factors to our base powder “A”. This blend has been created to alleviate stress, fight pathogenic bacteria, fungi, viruses, give a spectacular terpene profile, all while providing the perfect NPK ratios for the cannabis plants growth.

Our Full Spectrum formula allows advanced growers to achieve desired levels of calcium and nitrogen (B) while keeping the full dosage of our (A) at 1.75g/L to benefit plants complete integrity, growth and terpene profile. The science of our food works best when “A” is used at full strength 1.75g/L cutting the calcium “B” only to acquire certain lower levels at the two bloom phases.

*It is recommended to use 1.75g/L of “A” with 0.8g/L Cal + N during the vegetative phase. At this rate it provides approximately 1250ppm. *Day one of bloom requires the grower to cut “B” Cal + N to 0.6g/L keeping the “A” at the full 1.75g/L. At this rate it provides approximately 1125ppm. *It is recommended to cut Cal + N 21-28 days prior to harvest. **We advise to flush with water when ppm/EC gets above industry standard levels or plants may show signs of toxicity.
