Humidity issues. 6” exhaust 6” active intake on controllers.

Well, It would be helpful to know what exactly cold means. But for the most part cold and dry is far far easier to manage, and control as an indoor grower than hot and humid. Many indoor growers will only grow in the winter and spring for this reason. Humidifiers are relatively cheap. You could pour a ton of water on the ground or try keeping buckets of water in your tent but that would be real ghetto. I think you should buy a humidifier. Buy once cry once. unless you are going to need more of them. i have 4. You are most likely going to need a humidifier for drying you buds anyway. It's almost a must-have for indoor growers. It gets a lot more expensive when you get into too hot and humid. the lights for the most part make up for the heat, and give growers the day and night temperature differental they strive for. Just for the hardware my humidifiers average. 50 USD, but went through several smaller de-humidifiers before i found one that worked just okay,and that is a 300 USD unit. humidifier not too big a deal to grow top-notch buds. I am not a humidified salesman...lol 😂 but maybe i should be one lol I understand you want to not spend money. shits way to expensive and sheaply made it shard to want to buy anything nowadays. When i got started I was just going to get a good light and nothing else but i quickly realized that would not give me the best results. Things dont always have to be perfect either. plants are resiliant. you could also just try it out and see how it goes.
