Pocket CO2, Temperature, and Humidity Meter (CIS)

A thermometer, hygrometer, and CO2 meter in one! This multi-meter is an indispensable tool for anyone concerned about air quality in indoor spaces. This portable, accurate device allows you to monitor CO2 levels, temperature, and humidity quickly and effectively, which is essential for maintaining a healthy environment for plants and mushrooms, as well as your own living space.

• Easy to carry for measurements in different rooms.
• Measures CO2 from 400 ppm to 5000 ppm (1 ppm accuracy), temperature with an accuracy of ±1°C, and humidity up to 99% RH.
• Intuitive TFT LCD display for easy reading of results.

Why measure CO2?

The CIS Pocket meter is an essential tool for anyone concerned with health and safety standards in enclosed spaces. With rising CO2 levels in poorly ventilated spaces, this device offers a simple and effective way to ensure that air quality remains within safe limits. It is especially useful in classrooms, offices, or at home, to ensure a healthy living and working environment.

Importance of CO2 Measurement in Weed Cultivation

Accurately measuring CO2 levels is crucial in the cultivation of weed plants, as our ladies depend on carbon dioxide for their photosynthesis process. Optimal CO2 values can significantly improve the growth and potency of the plants. However, too high or too low CO2 levels can affect the health of the plants and reduce yield. The CIS Pocket CO2, Temperature, and Humidity Meter offers growers the ability to accurately monitor and adjust this vital parameter for an optimal growth environment. Increase the extraction if the CO2 level becomes too high, or reduce it if the CO2 level becomes too low.

The optimal CO2 level for the growth of weed plants is typically between 700 to 1500 ppm (parts per million). In a standard environment, the CO2 content is around 400 ppm, but for weed plants, an elevated CO2 level can significantly promote growth and flowering.

But it's important to know that the effectiveness of increased CO2 levels depends on other growth factors, such as light intensity, temperature, and nutrition. With higher CO2 levels, plants often need more light (lower your lamp) and nutrients. It's also crucial to keep environmental factors within safe limits, as too high CO2 levels (above 1500-2000 ppm) can be harmful to both the plants and people in the vicinity. Therefore, the use of CO2 must be carefully monitored and adjusted to the specific conditions in the grow space.

Importance of CO2 Measurement in Mushroom Cultivation

For the cultivation of psychedelic mushrooms and other fungi, controlling CO2 levels is also essential. Mushrooms require specific conditions for optimal growth, where the right balance of CO2 is a key factor. Too high a CO2 level can lead to elongated, weak stems and small caps, while too low a level can slow growth. With the CIS Pocket CO2, Temperature and Humidity Meter, you can finally map out and adjust the CO2 level for better yields from your grow kit. In addition to the CO2 levels mentioned below, good ventilation is essential to provide fresh air and oxygen and to remove excess CO2, which is crucial for the healthy development of mushrooms. Air exchange is actually the first trigger for a grow kit to start forming mushrooms.

For Psilocybe cubensis (B+, Mexican, Golden Teacher, etc.) you can use the following parameters:

For the growth of mycelium and the formation of mushrooms, a relatively high CO2 content is needed, usually between 5000 to 10000 ppm in the initial stage of mycelium growth. This high level stimulates the growth of the mycelium and prevents premature fruiting. When the mycelium growth is complete and it's time for the mushrooms to form (the so-called fruiting body phase), it's important to lower the CO2 level to about 1000 to 1500 ppm. This lower level is necessary to stimulate the formation of mushrooms. 

For Panaeolus cyanescens (Hawaiian / Blue Meanies / Copelandia) it's better to adhere to the following data:

During the mycelium growth, when the mycelium expands and colonizes the substrate, a higher CO2 level is desired. This is usually in the range of 5000 to 10000 ppm. High CO2 levels during this phase help promote mycelium growth and prevent premature fruiting. However, once the mycelium colonization is complete and the mushrooms begin to form, the CO2 level should be lowered to promote the development of fruit bodies. For Panaeolus cyanescens, this optimal level for fruiting body formation is usually around 1000 to 1500 ppm.

How do you use this CO2 meter?

The CIS Pocket meter is very user-friendly. Turn on the device, let it analyze the space, and read the measurements on the clear screen. Thanks to automatic calibration, it is always ready for use. The rechargeable battery allows for 4 to 6 hours of continuous operation, and with the included USB Type-C charging cable, it's quickly recharged. You can also leave it constantly on the charger, then the CO2 meter will not run out.
