"Photosynthesis is the process by which plant leaves make carbohydrates. Sunlight, CO2 and water are converted into carbohydrates and O2 by the action of chlorophyll in the chloroplasts of the plant.

Plants growing indoors under artificial light often lack enough CO2 to efficiently photosynthesize. When plants are able to maximize the process of photosynthesis, the result is larger plants with larger yields.

Co2 Mushroom bags can be used for both vegetative plant growth as well as for fruit and flower production. They cultivate CO2 24 hours a day with no need to refill bottles or use expensive CO2 production units."

ALL BAGS ARE 3KG AT THE TIME OF PRODUCTION - WEIGHTS MAY VARY AS THE MUSHROOMS/MYCELIUM CONSUMES THE SUBSTRATE THE BAG WILL WEIGHT LESS
