CO2

CO2 in hydroponics is crucial for the process of photosynthesis. Without this, your plants will probably stop growing correctly and become deficient. Photosynthesis takes place most noticeably in a plant’s leaf tissue. With the proper lighting, water and CO2, sugar production takes place to help feed the plant as it develops.

Most of the carbon in plants comes from the CO2 within the immediate environment. There’s a sufficient supply of carbon dioxide airborne for your plants to grow perfectly healthily. There are usually around 330 to 450 parts per million of CO2 in the air we all breathe, which is fine for most plants, as they need a minimum of 200ppm.

CO2 in the air is the crucial limiting aspect of growing plants hydroponically because water and nutrients are usually readily available. The carbon dioxide levels that you would typically find are enough. As this amount gets used up, the amount of carbon dioxide within a closed environment becomes more and more depleted.

Not replacing Carbon Dioxide can prevent plant development, so you should ensure a generous amount is always readily available.
Plants can make good use of considerably more than just the typically occurring levels of CO2; in fact, your plants will make excellent use of as much as 1,000 and 1,200ppm in the air.

So using extra CO2 within your growing room or tent will have a fantastic outcome on your plants’ development and health. They’ll be more vigorous and develop faster than ever before. You can expect to see as much as a 50% increase in your yields at harvest, everything else being equal.

However, too much carbon dioxide may be harmful, so you shouldn’t overdo things. A plant’s ability to transpire will reduce if there is too much CO2 around, adversely affecting the photosynthesis process and the number of nutrients plants can uptake or process usefully.

You can check the local carbon dioxide levels in several ways; one of these is by using a Digital Carbon Dioxide Controller to let you know how much CO2 is present and help you easily control the amount.

CO2 kits and systems work to supply and monitor carbon dioxide in a growing room or tent to foster better and more rapid plant development. The average level of CO2 in the air is about 400 ppm. So by enriching these levels to around 1,500 ppm, you will ensure that your plants will benefit.

The CO2 levels in your growing area should be a maximum of 1,500 ppm at the absolute top of the peak of supply, and no more than that for optimum healthy plant growth, although any level between 1,000ppm and 1,500ppm is going to produce vastly improved yields.

The plants’ flowering stage is the most important when adding any carbon dioxide to your growing room or tent. Adding CO2, notably during the first two or three weeks of the flowering stage, can often dramatically start flower production and increase flower sizes significantly.

Carbon dioxide enrichment works best when contained in a sealed growing room. You should avoid using air-cooled grow lights, as most of these are not entirely airtight and may draw air from your growing space. It also restricts any excess humidity from venting outside, so a dehumidifier is typically considered mandatory in such situations.

CO2 is a gas, and any gas density will increase as the temperature decreases. Different gases have different weights. Carbon dioxide is heavier than oxygen (O2), so we should expect CO2 molecules to sink below any oxygen molecules or any local layer of oxygen.
