5 Best CO2 Regulators For Grow Room 2020

Growing plants need some basic elements to survive. One such all-important element needed is carbon dioxide (CO2). It is even more important in a controlled environment such as a grow room. CO2 is needed because they ensure a high yield of crops; therefore it is necessary to invest in the Best CO2 Regulator for Grow Room.

CO2 regulators ensure your plants get an adequate amount of carbon dioxide which helps to support photosynthesis especially because there is lack of sunlight in grow rooms.

Why Use CO2 in Your Grow Room?

Currently, the atmosphere is made up of 400 PPM (parts per million) of CO2 regardless of the prevailing global warming. However, some plants (such as cannabis) can utilize as much as 1500PPM of CO2 that used to be in existence before now. Hence, the more CO2 is available, the larger the plants are and the more yield it results to.

This is where CO2 regulators are needed as they play an essential role in the success of your grow room. These regulators are made specifically to release a high amount of CO2. This is done by the release of carbon dioxide gas from the generator tank into the grow room to be used up by the plants.

Regulators are usually used for large scale growing operations or in places that deal with the professional growth of cannabis.

How to Pick the Best CO2 Regulators For Grow Room?

While there are many regulators on the market with the claim of being the best, you may end up purchasing one that’s not good enough to meet your needs. Hence, it’s important to consider some factors before purchasing a CO2 regulator; this will facilitate a good choice. The factors include:

Materials

It is important to consider what the regulator is made up of. Most regulators are made of brass (especially the products reviewed in this article), they are ideal hence you should consider one of high quality that will not be damaged by external factors. A very good casing ensures the components of the regulator are shielded against moisture and dust.

Ease of Use

This is another important factor that must be considered if you hope to enjoy the product. Since CO2 is just one part of the system, it’s ideal that it is user-friendly. There is a need for comprehensive instructions on the use of the equipment to enable users quickly get a hang of it. Purchase a regulator with self-calibration features as this will ensure you don't have to adjust it yourself thereby giving you ease of use.

Size of Grow Room

Before buying a CO2 regulator, it is necessary to get the measurement of the grow room to avoid buying one that is too big or too small. CO2 regulators have a limited size of growing room space they can cover to ensure optimal performance. Hence depending on the size of your grow room, you may need to install more than one CO2 regulator.

Sensor

The sensor is one of the key features of a regulator. Sensors ensure the unit will turn on its own when its time (usually during the day). While at night it is expected to automatically turn off without having to press anything. If this is not the case, then you have wasted CO2 as well as energy.

Display

The display of the CO2 regulator should be easy to view regardless of the time of the day. Whether its day or night, you should be able to see if the level of CO2 concentration is right and if it’s not, then more needs to be released and vice versa.

Warranty

All CO2 should come with some form of warranty even if it’s just for a year. The longer the warranty, the better the product. A warranty ensures that the product is shielded against defects and that there’s a replacement from the manufacturer once an issue arises so long as it’s not due to your negligence.

High-Pressure Gauge

Most CO2 tanks have 800psi, but the CO2 regulator to be bought should have at least 1000psi. it should also have a low-pressure gauge with reading between 15 to 30 psi and should not exceed 200psi. When it's reading 30psi, it means that the regulator output is a maximum of 15 psi and anything lower than that means it’s less than 10psi, a number that is generally not suitable for CO2 release. If a low-pressure gauge reads more than 200 psi it then means that adjusting the pressure to a suitable range (between 10 to 30 psi) will be difficult.

How to Setup CO2 Regulator in Grow Room?

To set up a CO2 regulator for your indoor garden, you will need the following materials:

  • 20 pound CO2 tank
  • Tighten control CO2 regulator

The CO2 regulator comes with plastic washers, 12 feet of dispensing tubing and instructions that include flow meter setting and a timing chart.

The CO2 regulator is a device that uses a pinwheel knob to control the flow of the CO2 from the tank to the output tubing and ultimately enriching your garden.

To set up a CO2 regulator take the following steps:

  1. 1
    Attach the regulator to the tank by installing the plastic washer and then securely fasten the brass output to the thoracic connector located on the tank
  2. 2
    Attach a simple CO2 to the bottom of a reflector
  3. 3
    Put the CO2 regulator into either a 24-hour time or into a CO2 monitor-controller
  4. 4
    Once either the 24hour timer or monitor controller is set up correctly, you are ready to enrich your garden with CO2

While installing, take note of the following:

  • Ensure the regulator's face is pointing outward to be easily recognized and monitored
  • For flowering gardens, we recommend CO2 setting between 1200PPM and 1500PPM during daylight periods only
  • For larger rooms, the regulator flow may be very high; in this case, it is recommended you use an inline CO2 heater. this helps to protect the CO2 regulator and ensures it lasts longer
  • The CO2 heater should be placed between the CO2 regulator and the tank. This prevents cracking of the regulator, internal diaphragm and possible regulator freeze-up that occurs with high CO2 flow conditions
