Deciding how to control the CO2 level in your grow room – is a pretty tricky choice, none will argue! You want to supply higher amount of CO2 PPM for your plants, but also you don’t want them to get choked-off.
You know the plants need more of CO2 for accelerated photosynthesis. But at the same time, you can’t let the overflowing CO2 from that little grow space to be diffused into your living space! Then there’s this issue, how much flow of CO2 to set in which plantation stage?
In this jam-packed schedule of clock-wise life routine, surely we all strive for a better yield with increased harvest. Still we wish,we didn’t have to check on the CO2 concentration in grow tent air, now and then, every three-four hours!
Well… Now what’s going to amaze you is, all your problems have a pretty simple solution – using a CO2 Controller or Regulator! If and only if you’re into better harvesting with lesser troubles, this onesurely tops the smartest solution available on market.

Frequently Asked Questions (FAQ)
Why does a grow room require CO2?
While breathing, humans inhale Oxygen and exhale Carbon dioxide. On the other hand, trees and plants inhale Carbon dioxide and exhale Oxygen. Which is why along with water and light, Carbon dioxide is an equally vital component for photosynthesis during plant growth. In higher-intensity light (such as LED grow lights, MH, HPS) environments, plants can increase the rate of photosynthesis – if and only if a higher amount of CO2 is supplied too! The increased photosynthesis results into producing more energy, eventually faster growth and bigger yields (up to 20% on an average).
Adding to the brownie points, greater CO2 supplementation makes the plants heat-resistant and stress-resistant.
What amount of CO2 should I give to the growing plants?
There used to exist a much higher level of CO2 in the atmosphere when plants were evolving, thousands of years before from today. That elevated density was nearly 1500 PPM. As a consequence, plants could process more photosynthesis reaction and evolve more, grow more.
Compared to that, in this 21st century, the CO2 concentration in air is not any higher than 400 PPM. But surprisingly, plants have still not lost that potential of using use more CO2 to produce more energy!
Implies that, given the right type of circumstance with brighter light and increased CO2 provision, these present era plants can still reach that maximum effective stage of photosynthesis→maximum energy production →maximum possible growth.
To achieve this efficient optimal growth level, plants can conveniently use 1200 – 1500 PPM of CO2 concentration, without exerting themselves.
But words of caution, anything beyond 5000 PPM of CO2 level will prove to be lethal for your plants!
Why do I need to control the CO2 level in my grow room?
Certainly adding CO2 to your grow room will boost up yields and generate manifold healthier plants. Insufficient CO2 can even cause the plants to die!
But more concentration than the optimal CO2 level will also start to suffocate your plants…
If the amount of CO2 in grow room environment reaches above 1500 PPM, slowly it will have an adverse effect on the plants growth. And if this CO2 density crosses the limit of 5000 PPM, unfortunate to say – your plants will be on the death verge.
This is precisely why, in order to protect your crops from the toxicity of accidental over-CO2-supplementation – your grow room needs a CO2 controller.
How do I maximize the CO2 level using a regulator?
To maximize your efficient output, first you have to pick a CO2 regulator with just right characteristics!
Step- 1: Choose one with a high-quality construction material and easy-to-use.
Step- 2: Calculate the size of your grow room and check whether it needs one or, more than one CO2 regulators.
Step- 3: Make sure the display and sensor works properly.
Step- 4: Do not forget about the warranty period and enquire whether the customer care will co-operate with further defects and replacement issues.
These are some major crucial factors you should keep on mind while purchasing an ideal CO2 regulator for the grow room you love.
