Carbon dioxide (CO2) is essential for plant growth. In an enclosed growing environment like hydroponics, the average level of CO2 in this growth atmosphere should be about 350 PPM [parts per million]. The optimum agreed level varies between 1000-1500 PPM ranges.
The CO2 is important for healthy plant growth that improves yields as well. However, providing CO2 during day time and controlling its level is also of utmost importance. The continuous air flow in and out the growing unit allows healthy plant growth. To tackle this need LTL CO2 – Daytime CO2 Controller is the most effective device.
Features of LTL CO2 – Daytime CO2 Controller
The LTL CO2 – Daytime CO2 Controller utilizes a series of blinking LED lights to indicate the current PPM level. It also features an external CO2 sensor to offer you with the most accurate readings. Details of these and its some other features are:
The LTL CO2 – Daytime CO2 Controller is a water-resistant CO2 controller but not water proof so install it at a place where water is not adjacent to this controller.
It comes with a built-in photocell that automatically deactivates CO2 during nighttime. During daytime the green LED light on the top right side labeled daytime will illuminate.
This is an analog controller and does not contain digital display to communicates the current PPM setting. Thus, it uses the series of flashing LED lights on the front of controller to indicate the current PPM reading. The number of times the red and yellow lights blinks communicates the PPM value.
The external CO2 sensor is useful for the most accurate readings. But ensure to place it at a plant height and at a location with sufficient air movements.
You can change the setting using two options, CO2 PPM and dead band PPM. The CO2 PPM is your desired minimum set point and dead band PPM supports as a buffer. An illustration will help you understand this. Suppose your CO2 PPM setting is 1100 PPM and dead band PPM is 100 PPM and now the CO2 level drops below 1100 PPM, the CO2 device will get activated and will remain on until the CO2 level reaches 1200 PPM.
Calibrating sensor is also important so that it provides you with the exact readings. For calibrating take the sensor and Daytime CO2 Controller away from the crowd to read the current levels and bring the levels between 300-400 PPM.
- Ensure that the device you connect to the LTL CO2 Controller has proper voltage otherwise it can damage the controller.
- Always connect the device using the outlet on the front face of the controller.
- The safety and operating instructions are readily available for ease in using the device.
- Place LTL CO2 – Daytime CO2 Controller at least 8 ft away from other electronic device such as electronic ballasts or ozone generator that generates large amount of noise.
- For safety measures, always insert the main plug into the power socket outlet that is protected with earth contact.
How is a Daytime Co2 Controller different from a DIY CO2 controller?
Ready to use CO2 Controllers are tested for performance and are more efficient. Since there are a lot of ways to create your own Co2 Controller, people use it as they are much cheaper, unaware of the fact that the efficiency cannot be as good as those products which are tested by time and people.
Why DIY co2 controller is NOT the real thing ?
CO2 Controllers is a product which is required for better performance and growth of the plant. using a Homemade DIY CO2 controller will leave you without the knowledge of what the output is going to be. With a ready to purchase CO2 controller, which comes with a manual and years of use, you get the know how of people and can expect what the output is going to be. The real thing or not is up to you to decide.
How does homemade co2 controller work?
Home Made Co2 controllers are cheap. they are highly customizable too. But can you still manage to build a product which could match the expertise of those in the industry? Home made controllers for Small Tents and boxes are ok. But not for large scale growing.
What is the temperature level and the humidity level to be maintained while using my DIY CO2 controller?
Growing indoors is not an easy job and CO2 only makes things bit difficult for you as it is an additional responsibility that needs to be handled vigilantly. The right temperature is between 85oF (30oC) and 95oF (35oC) in your grow room while humidity level must be 70% for vegetative and 60% for plants in their flowering stages while running CO2.
What is the lumens recommended for DIY CO2 controller?
Its recommended that plants get at least 7500-10000 spectrum of light per sq.ft which will enhance the CO2 to deliver effective results.
If I am building a DIY CO2 controller what should be the CO2 level that is to be maintained?
For indoor crops the most suitable range is 1200-1250ppm. Do not exceed the said limit as it will result in poor yields or phytotoxicity in the environment which can prove detrimental.
When is the best time to use DIY CO2 controller?
First thing you need to ensure that you have eliminated any chances of plant problems. This is the initial point which needs attention as plant problems can occur at any given which can deteriorate your yields. So make sure you have fixed certain issues before considering CO2 for indoor growing.
Can I keep the exhaust fan on while using my DIY CO2 controller?
If you are planning to maintain a stable CO2 environment in your grow room, then it is important (rather mandatory) to switch off the exhaust fans for a good time. This will balance the CO2 level in the indoor grow room thereby pushing the plants to grow healthy and rich. You also need to ensure any leakage points or fan holes are also sealed to ensure CO2 stays in the grow room for optimum effectiveness.
Are there any alternatives other than DIY CO2 controller available in the market?
Yes, you can always go for chemical combos (hydrochloric acid and bicarbonate soda) which release CO2 in the atmosphere. Other commonly used methods include brewing beer in the grow room (by product is CO2 via fermentation), gas heating (CO2 is released by combustion of propane gas), placing dry ice (melting of ice released CO2) in the environment.
Can too much exposure while handling DIY CO2 controller affect me and my family’s health?
As a general rule of thumb, it is better to use only pure food grade CO2 even though there are many types of CO2 available. You can ask your supplier for more product options.
