Just get a good fan that exchanges the air at least every five minutes. Cooler temps r not a horrible thing. Just make sure to not let them get too hot. In nature temps go up and down. It's ok.
MMJ Reviewed by MMJ on . Warming and Cooling the Room Alright, I'm starting up my first grow and I'm being relatively serious about it on a small scale. It's a box going to be 6ft x 23 inch x 23 inch for personal grow. But where I live gets 17C degrees cooler than where the plants want to be during the winter months and our houses are poorly insulated. That's because during the summer months we exceed 40C degrees. I need a way to cool and warm my room that can follow a thermostat. I want to keep in that 24 degrees celcius sweet spot. Thanks in Rating: 5
