Increased co2 The benefits of increased carbon dioxide levels within a greenhouse are widely accepted and understood, and include earlier flowering, higher yields, improved stem strength, and larger flowers. No set up or maintenance EZ CO2 is far less costly than tanks and generators and is incredibly simple to use. Just place it and leave it! It's that simple. You'll reap the benefits of increased CO2 PPM without any of the work or hassle of the other methods. MEDIUM = MORE CO2 We've increased the amount of medium in our bags, compared to others on the market, so you get more CO2 for your money. Simple and uncomplicated EZ CO2 gives off no odors or heat, and is completely self-sustained. It's already giving off CO2 the moment you buy it, and it continues to produce CO2 for the next 6-8 months. ABOUT EZ CO2 is a natural, safe, and inexpensive way of providing your plants with carbon dioxide (CO2). CO2 tanks and generators can be expensive and time consuming, but EZ CO2 requires no set up or maintenance and is easy on your budget! WHY ADD CO2? The benefits of increased CO2 levels within a greenhouse are widely accepted and understood, and often include earlier flowering, higher yields, improved stem strength, and larger flower size. This is because plants use the process of photosynthesis to convert water, sunlight, and CO2 into sugars and other materials essential to their growth and overall nutrition. When there is more CO2 in the air, plants become more efficient at absorbing it and processing it. Faster conversion of CO2 into sugars and nutrients results in faster plant growth. Additionally, plants take in CO2 through small pores on the underside of their leaves called stomata. When the levels of CO2 are higher, the plants do not need to open up these pores as often or as wide, resulting in less water loss and reduced likelihood of taking in damaging air pollutants.
