Naturally, all plants have different needs – do you have any plant specific guidelines?
The short answer is no, we do not offer plant specific guidelines. The reason is the long answer.
Well, when it comes to CO2there are four main groups, some of which don’t use carbon dioxide.
1. Green plants (the green colour comes from the green pigments in chlorophyll molecules)
These plants arecompletely autotrophic. To thrive, autotrophic plants need only solar energy, carbon dioxide, water, and a few minerals. All autotrophic plantsuse carbon dioxide for photosynthesis.
2. Semiparasitic plants
Semiparasitic plants, on the other hand,can't quite do it all from just water, CO2, and sunlight(and a few other nutrients like nitrogen).
They also have totake some nutrients from an autotrophic host plant. They actuallyconnect themselves to another plantand take some of the food they need from the host plant.Mistletoe is an exampleof this kind of plant (which is actually considered a fungi now).
Semiparasitic plantswon’t need as much CO2.
3. Insectivorous Plants
They use carbon dioxide for photosynthesis, but still needs a little something extra.
For example: Venus fly trap and pitcher plants catch andslowly digest insects and other unfortunate little animalsthat fall into their traps. Insectivorous plantscan live without catching animals but they are a lot healthier if they can catch an occasional bugnow and then.
4. Holoparasitic plants
Like semiparasitic plants, theyhave to be directly connected to an autotrophic host plant.
They have to get all their nutrients, energy, water, and carbon from the host plant they are attached to. But these plants have no green parts andcan't perform any photosynthesis, so don't use carbon dioxide.
Since the vast majority of plants grown by our customers are those that absorb CO2during photosynthesis,we don’t offer any plant specific guidelines.
FAQs
Please note, that as CO2 is heavier than air, the exhale CO2 bag should be hung at the top of the grow room to deliver a shower of CO2 over your plants.
When to use CO2 bags in a grow tent? ›
When is the right time to introduce carbon dioxide in an indoor grow environment? For those that are looking to add carbon dioxide to their grow room, the flowering stage is the most important. It is critical that when you supplement CO2 to your crops you do so within the first 2-5 weeks of flowering.
Do CO2 bags work? ›
That being said, with a co2 bag, you can get a max of around 1500 par if available without burning your plants. Without co2, even 1000 par can be too much. Co2 expands the capabilities of your plants to intake everything, but you must be ready to give it everything as well or you're just wasting money.
Where are the three places that CO2 can be stored? ›
The three main types of geological storage are oil and gas reservoirs, deep saline formations, and un-minable coal beds.
What is too much CO2 in a grow tent? ›
Supplemental CO2 is useful for plants growth. However, a sealed grow room can trap dangerous levels of carbon dioxide that can lead to severe health effects such as dizziness, unconsciousness, or can even be fatal.
Is CO2 better for plants at night or day? ›
The justification for not providing additional CO2 for plants during the night is that plants only require CO2 during the day for photosynthesis. At night, there is little or no photosynthesis and, therefore, there is no reason why CO2 should be maintained at artificially elevated levels.
Does CO2 really increase yield? ›
Studies have shown that higher concentrations of atmospheric carbon dioxide affect crops in two important ways: they boost crop yields by increasing the rate of photosynthesis, which spurs growth, and they reduce the amount of water crops lose through transpiration.
How do I know if my CO2 bag is working? ›
You know it is working as the material in the bag will become white. Breaking the material up gently will keep the production levels high. The CO2 produced in the bag is then released into the growroom via the vents in the bag.
Where to hang ExHale CO2 bags? ›
Because CO2 is heavier than air we recommend hanging the bag one to two feet directly above your plants. Each bag comes with a hanger but how you attach it is up to you. After hanging your bag, a continuous shower of CO2 will fall directly onto your plants.
How long does it take for CO2 bag to activate? ›
The bag will start to produce co2 over 2-3 days at an optimum temperature of between 25-30 degrees. Optimum humidity levels are important; therefore, if the bag produces too much moisture , simply pierce the bottom of the bag with a pin to drain excess moisture.
Q: How long does it last? It produces Co2 for about 4-5 months but takes about 1 month to actually start working as … David S. Simply take the exhale bag from it's packaging and place above plants as co2 rains down.
Are exhale CO2 bags safe? ›
ExHale CO2 is a passive delivery system and will not cause harmful concentrations of carbon dioxide. Ingestion-Not a relevant route of exposure (gas). Remove bag from area and provide fresh air for 10 minutes.
Where should CO2 cylinders be stored? ›
The CGA recommends that CO2 cylinders be stored in areas with a temperature less than 125 oF (51.7 oC).
- Never store a charged CO2 cylinder in a passenger vehicle or in the cab portion of any vehicle.
- Empty CO2 cylinders should be stored with the valve tightly closed.
As more people remain in a room, CO2 levels increase quickly if there is not enough fresh air coming into the space. High indoor CO2 levels can cause tiredness, headaches and other symptoms. Increasing CO2 levels show you that the space is not well ventilated.
Where should a CO2 burner be placed in a grow room? ›
CO2 Burners - best for grow rooms
These are housed in a metal box that is hung from the ceiling of the grow room above the canopy of the plants. A tank of either liquid propane, or a natural gas is then hooked up to the regulator, which is then plugged into a CO2 controller.
