Question to IRI have a question in to IR about dosing CO2. To me the growing area looks fairly airtight. Could they dose 1200+ppm of CO2 in there?

They've responded and are asking the growing & cultivation team. I asked my question fairly late on Friday and got a response Saturday at 8:40pm. Pretty sure the team is working hard for SH'ers at the moment.
GLTA!
