The Top CO2 Regulators

If you’re looking for some ways to help increase the carbon dioxide levels for your plants, you’ve come to the right place. This article will showcase some of the top CO2 regulators that will help you to monitor and adjust the carbon dioxide levels in your growing space.

What are They?

CO2 regulators work to help create carbon dioxide. They will release certain amounts of carbon dioxide depending the amounts and times that you set for it to do so. Sometimes these regulators can also burn certain things to help create carbon dioxide for your plants.

Why Do Plants Need Carbon Dioxide?

Plants need carbon dioxide in order to help them with photosynthesis. The plants will absorb the carbon dioxide through their stomates which will then help the plant to turn green and grow.

How Much Carbon Dioxide Should My Plants Have?

The right amount of carbon dioxide your plants need depend on how many plants you have and how big your growing space is. You always want to check the CFH rating of a regulator and look to check your CO2 regulator’s directions. Typically, 1 lb. of carbon dioxide is about 8 cubic feet of gas. However, always check your regulator to make sure you emit the proper amount of carbon dioxide. Too much carbon dioxide can be harmful to your plants and if you breathe in too much carbon dioxide it can be deadly. Ideally, you should emit carbon dioxide levels anywhere from 1,200-1,500 PPM (Parts Per Million).

Overall, be sure to always check the right amount of carbon dioxide you should use. It’s best to check your regulator’s user manual to make sure you emit the proper amount with your regulator.

What is a Solenoid Valve?

As you’ll find with many of the CO2 regulator models, they use a solenoid valve. This is an electromechanically operated valve that uses an electric current to help emit carbon dioxide to your plants. It’s a helpful thing to have with one of these regulators so be sure to check to see if the model you are interested in has one.

Pros and Cons of Using Carbon Dioxide

There are quite a few pros and cons you should take into consideration before using a CO2 regulator to make sure it’s something that’s right for you to use with your plants.

Pros

  • Carbon dioxide will help to make your plants grow faster. It will also help with giving you a bigger harvest.
  • Carbon dioxide can work well in hot temperatures so you don’t need to pay as close attention to the temperature amounts like you would need to if you didn’t use it.

Cons

  • In order for carbon dioxide to work well in your grow space you need to make sure you have very bright lights in it.
  • You’ll have to carefully monitor the carbon dioxide levels to make sure they aren’t being overly emitted.
  • Carbon dioxide regulators can be a little expensive. Because of this, it’s best to make sure that you plan out if you really need a regulator before investing in one.

Can I Use Carbon Dioxide Regulators at Night?

It’s best to not use carbon dioxide regulators at night because it would just be wasting carbon dioxide. Your cannabis plants won’t be absorbing the carbon dioxide emitted because they only do so when there’s light available. It’s best to turn the carbon dioxide regulator off at night to give your plants a break and then restart it once daytime comes around again.
