So where have we got to with the CO2?
First of all another big thank you for EddyZ for all of his help.
We are burning propane gas to produce our CO2.
We set our controller for 900ppm to 1300ppm.
We put in four big burners but our patch is very well sealed and it turns out that we only probably needed one small one.
We’ve found out that just the four very small pilot lights are creating around 2000ppm over night and we burn very little gas.
We pull the plugs out of the burners at seven o’clock in the morning to stop the heat from the burners pushing the vents open.
On an average day the vents open at around 8 o’clock in the morning and any remaining CO2 is lost.
The plugs go back on in the evening at 9 o’clock because the vents don’t shut until the sun goes down.
The CO2 is definitely, in our opinion helping our plants.
The window with extra CO2 is probably around 4hours.
This is our early pollinated 1911 in a very “Happy” patch.
