As plants need CO2 is there any plants that I can grow in my greenhouse that feed off oxygen and give off CO2?

Question

Just to ballance things out. Thanks.

Answer 1

All plants require carbon dioxide to survive, and give off oxygen. I know of no plants that work "backwards". That's why trees and plants are important to our environment. They give off the oxygen we humans need to survive, we humans give off CO2 that the plants need to survive.

Answer 2

Nope, ventilate whenever possible. I've seen some greenhouses that have rabbit production under the benching. Larger production facilities employee the addition of CO2 from bulk liquid tanks to promote plant growth. Hemp growers are know to use Co2 bottles, like those for soda pop dispensers, in their indoor growing spaces. I've been growing in my 4500 sq ft greenhouse for over 20 years and have never had the normal oxygen level fall more than 1 to 2 percent at night. Normal O2 concentration is 21% by volume.

Answer 3

Plants engage in two major processes: photosynthesis and respiration.

Photosynthesis is a process whereby plants manufacture simple sugars, using water, carbon dioxide and light energy.
A 'waste product' of this process is oxygen, which is given off as a result of the water molecule being split.
Thus in photosynthesis, oxygen is given off by the plant.
Note that as photosynthesis requires light and doesn't occur during darkness.

Respiration is the process whereby some of the more complex chemicals synthesised from the products of photosynthesis are broken down in the cells to produce energy.

Respiration requires oxygen, and thus plants take in oxygen, and the waste products of respiration are carbon dioxide and water.

One difference between these two processes is that plants continue to respire all the time, whereas they only photosythesise during the day.

The rate of photosynthesis can be maximised by ensuring composts are at field capacity, correct levels of nutrients to ensure chlorophyll production, a temperature above 6C, extending daylight through 'daylight' lamps, and enrich carbon dioxide levels through the release from CO2 gas canisters.
The latter is used commercially, but is unlikely to be worthwhile to the amateur, as normal ambient CO2 levels are perfectly adequate for normal plant growth.

Answer 4

Thats your job, some people talk to their plants for the CO2 they provide, so when you water them in the mornings and evenings you'll be giving them all the carbon dioxide they need - plus there's always some in the air already.

Answer 5

Plants give off Co2 at night so you should be ok on that front.

Answer 6

You don't need to - Plants use oxygen and give our CO2 at night.

Answer 7

Plant some humans.

Answer 8

Nature is balanced.
When the temperature is warm enough leave the door open.
If it is too cold you will need an heater and that will produce CO2.

Answer 9

holly ****.......I'm going to build myself a pollygreen house soon, and now your worrying me ........don't i just put seeds in the ground and bingo! I've grown a supermarket?

Answer 10

Hmmm....never heard anything like that before...
