Hi All,
Re-filling FE canisters is proving very expensive over here so have made some enquiries about getting a pub CO2 cylinder.
Managed to get my hands on one that I can get refilled for free when I need to but I'm unsure about the gas mix they use for refilling.
The mix is 50% CO2/ 50% Nitrogen. Now I know we add nitrogen in ferts but does this mean that injecting nitrogen is safe?
If nothing else, I assume it means that I will need to inject 50% more CO2 than I would if I had a 100% CO2 filled cylinder?
Thanks
