Keep the tent or change to green house type room

Facts: I have a 1.5Mx1.5M x 1.7M height tent, small portable AC unit, Co2 tank, Dehumidifier, Mars hydro led lights, inline fan…. Placed on large covered balcony in Thailand, plenty of indirect sun but no direct sun. Problem: When using AC and co2 , the AC unit pulls ALL the co2 out since it has a 6 inch exhaust vent. My two solutions are get rid of the tent and buy 3 inexpensive sliding glass door units and put them against the wall, install a split AC unit (no more sucking air out of the room.) Cost $650-760 USD. It would give me a little more space also. Or keep the tent and stop using the co2. I do see a difference using co2, or any other ideas. thanks
