Product Nutrients Grow A&B

Grow A&B

Vegetative Growth

Our GROW A (3-0-2) and GROW B (1-2-4) formulas provide the basis for vegetative growth. High performance ingredients enhance photosynthesis, nitrogen uptake, and micronutrient delivery.

Rx Green Technologies’ natural-based program contains a full spectrum of nutrients at balanced ratios for superior plant performance. Developed for growers who want to improve both yields and quality (terpenes, cannabinoid profiles, and potency) through a simple program.

Phosphorus Uptake: The organic acid formulation of our phosphate technology slows the oxidation of phosphorus, resulting in more plant-available phosphorus and less danger of phytotoxicity.

Improves Nitrogen Usage: Our organic acid technology enhances the fixation of CO2 through natural plant metabolites. Metabolites stimulate the plant’s metabolism, increasing photosynthetic processes and carbon fixation. This encourages the plant to uptake more nitrogen, ultimately resulting in increased plant growth rates and greater plant biomass.

Built in Terpene Enhancer: Naturally-occurring compounds enhance the shikimate pathway, which converts carbohydrates into three amino acids: tryptophan, tyrosine, and phenylalanine. These amino acids are the precursors for a variety of molecules that naturally protect the plant from environmental stresses and pests.

Amino Acid Chelates: The amino acid complex keeps micronutrients in an optimal form until they are ready to be utilized by the plant. These amino acids are neutrally charged and therefore easily absorbed by the plant with minimal energy loss. Our micronutrients are more easily absorbed than other products, supporting key physiological processes like chlorophyll production, carbohydrate metabolism, and enzymatic activity.
