Truth be told, anyone who gets into indoor cannabis farming, expects to have high yields and be professional while at it. And there is nothing wrong with this. However, you do need to have your grow room set up in a way that will ensure you receive exactly what you wish for. While there are many considerations and setups you ought to make for your grow room, in this article, we shall zero in on CO2 generator setups.
Yes, using fermentation, dry ice and mushroom boxes just won’t cut it. In addition, you cannot afford to sit pretty and wait for global warming to rise and CO2 levels to rise as well to come and save the day.
At the current time, the CO2 levels are 400 parts per million or thereabouts. Sure, you may have come across some blogs that state the levels are at 350PPM but be advised, this data is from years ago. The statistics vary from time to time depending on the prevailing time and weather. Yes, you should be aware of the real climate change. We may want to bury our heads deep in the sand and be devoid of this fact but it is real and should face it head-on.
But that aside, when you are growing cannabis in a grow room, you have the ability to raise the CO2 levels in the room to about 1500PPM. At these levels, your weed will flourish and you will have a high yield – better than you had even anticipated for. At these levels, you will have up to 30% more buds at the time of our harvest. But be warned. Too much of anything is poisonous. Going beyond this CO2 levels will suffocate your cannabis rather have them flourish.
That said, and before we proceed any further if you intend to increase the levels of CO2 in your grow room, you should have proper ventilation. Have the air move around.
Regulators, Generators, and Controllers Explained
Now, it can be easy or it can be hard. With the information provided, hopefully, it will be easy. That said, there are two ways you can approach your set up. First, you can either get an all-in-one ready to use CO2 generator or buy the setup in parts and assemble them yourself. Whichever method you use it is imperative to have a way of controlling the release of CO2 into your grow room.
With all-in-one systems, there are those that burn butane or propane to release the CO2. But these units also release humidity and heat into the room. If you are not willing to deal with the latter, then go for a CO2 tank coupled with a regulator and a controller. The controllers are designed to detect the CO2 levels in the air and the regulator releases just the required amount of CO2 in the air.
How Much CO2 is Enough?
Rather than guessing the proper levels of CO2 in your grow room, it is important if you invest in a controller. It is even safer. Working with a tank and a regulator only means you will have to work with rough estimates. So just in case, your budget does not allow you to get a controller, here are some tips to help you out.
First and foremost, check on the CFH (cubic feet per hour) rating. This is when you are working with a generator. Second, you should measure the size of the grow tent and get its cubic volume. For this, you will have to multiply the height, width, and length of your room.
With a CO2 tank, you can set the flow rate you prefer. While setting the flow, you should remember that the cannabis plants only make use of the CO2 during the day. At night they use Oxygen.
That said, below are some points to take note of:
- A single pound of compressed CO2 spreads out to 8.7 cubic ft. once released into the room.
- To find out just how much flow you would need, multiply the cubic size of your grow room with 0.0015 or by 0.0013 if you are long to play it safe.
- Set the regulator to the right PSI
- Set your timer to have just the right amount of gas released.
Quick question, why is a timer necessary? Well, while CO2 is important for your cannabis growth, it can be harmful to humans who use oxygen all the time. You do not want to be around CO2 for too long.
Now that we have gotten that out of the way, let’s jump into a review of some of the best CO2 regulators for growing cannabis.
