## Description

Product description Photosynthesis Plus enhances biological function at the foliar and root substrate levels, transporting artificial light energy / sun's energy and speeding carbon, mineral and nutrient transfer to plants at much improved rates! The consortium of cultures contained in Photosynthesis Plus is made up of two select Photosynthetic bacterial strains and four Bacillus strains, fermented together over six days, resulting in a complete ecosystem in the bottle. Ecological Laboratories, Inc. claims to be the only worldwide manufacturer of a photosynthetic bacterial ecosystem that is shelf-stable for two years. This same culture group manufactured by Ecological Laboratories, Inc. (QUANTUM GROWTH) is used on tens of thousands of acres of food crops worldwide! Photosynthesis Plus is grown in the bottle you will receive and must remain in this ecosystem throughout its shelf life (two year shelf life unopened, one year shelf life after opening). Photosynthesis Plus has a strong hydrogen sulfide odor which will flash off after opening "if it doesn't smell like Microbe Life, it doesn't work like Microbe Life." APPLICATION USES: Photosynthesis Plus may be used indoors/outdoors as a foliar spray or added to solutions for all hydroponic, NFT drip, aeroponic, irrigation, and continuous liquid feeding systems. MEDIA USES: Photosynthesis Plus may be used with all soil and soilless media including Coco Coir, and is compatible with all nutrient programs - Always check pH and CF levels when using.
