Hey there BisonKit, man if you live in the tropics you should really invest in an air conditioning. That's because AC does make the air drier , it's really an investment for you that you can keep for many many grow cycles. the quality of the final product will be much better also, potency and even the final yield because of optimal conditions. See : growth rate is determined by VPD Vapor Pressure Deficit which is the relationship between the temperature and the humidity, learn more here : https://pulsegrow.com/vpd basically the point is that it's very important to keep the correct humidity. The only thing i will add now is that you should be careful about the AC : dont extract too much air too quickly, and make sure you're recirculating the air just a bit also. Hope this helps ! 🚀
