Sounds simple right? Yet it has been a total nightmare. I live in a tropical city, 27-30 degrees C all year round, with humidity levels ranging from 75 to 95% all year. So a nightmare scenario for growing without mold. When I use the AC it will drop the temp to whatever I want and also lower the humidity. but the dehumidifying performance of the AC is only good when you set the temperature lower than 25C I also have a dehumidifier on the room and it alone can hold around 50% RH. at the expense of increasing the temp to 32C The problem is I can never find a sweet spot when both the AC and Dehumidifier are on. If I turn on the AC to keep temps in check around 30C (remember this is a sealed CO2 enriched room) and also the dehumidifier it will keep RH around 30 to 35% which is too low for veg. Is 32C safe to run with CO2 enrichment ? The roots are safe at around 20C by using a water chiller.
