OK, So... A 4x4 tent with co2 injection needs cooling. SWIM need a portable AC to do this, one with dual hoses to not suck out the Co2. The portable AC is going to be hooked up to a digital environment controller that will tell the Unit when to come on and off. So the unit MUST BE ABLE TO COME BACK ON AFTER POWER IS OFF AUTOMATICALLY. A minisplit or window unit is not going to be an option because there is no place to vent the air, the tent is in a spare bedroom and the houses central air will be used to cool the area around the tent where the AC would be exchanging air from. SWIM has carbon filter and exhaust fans etc. to play around with. Can anyone recommend a reliable dual hose unit? Looking to keep it around 500$ or less and it is very important the unit can turn on automatically via the digital controller throughout the day.
