How much CO2 do plants put out while they sleep???

Soooo. Plants are absorbing AND expelling co2 and o2 all the time. The reason growers add co2 is that c3 plants can take advantage of greater than average percentages of co2 and therefore, fix sugars at a higher rate.
This comes from a belief that co2 receptors developed in c3 plants during a period (mesozoic) when co2 levels were much higher than they are now and o2 levels were much lower.

for you desert growers, is that with high heat AND low humidity, your plant will be respiring faster than it can uptake water. It will close its stomata to reduce water loss..and bam. No more co2 is absorbed for production. What the plant then does is a very wasteful process of using rubisco to creat sugars by combining o2 with Rubp instead of co2. This is half as effecting and also creates a toxic C molecule that has to be broken down. I can't remember the specifics but it makes some sort of glypholate? Acid that then has to be evbtually broken down into glycine I think it is
You might be referring to photorespiration which is a process close to what you describe which assists plants to mitigate some of the harmful affects of processes that kick in during heat stress like oxygenation, but yes it reduces. I think glypholate = glycolate.

from my reading.. they use co2 during the lights on period.. and produce co2 at lights off..

7 months later big deal.. first off.. these forums are online allday.. so this information is being read by people all the time.. so getting the right info is what we need.. so if u see a thread thats not active.. but is providing misinformation.. WAKE THAT THREAD UP.. and let people know .. this is a site used to help people become better growers/farmers/breeders. and to inform people.. who cares if its years later. as long as the information is solid.
