CO2: The Do's and Dont's (Q&A with Donnie from MyCO2) | GroWell (2024)

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.
