Hello everyone
I have a 4 tier mini greenhouse that I would really like to make my highland chamber and day temps are 78-75 F
And the nighttime temps are usually the same as the day time temps. I use a zoomed hygrotherm to control the humidifier and fan but the fan doesnt seem to make the mini greenhouse cool enough at night. I want to be able to make it go to at least 55 degrees F. But i dont know what to use. I have thought about using a thermoelectric peltier cooler but not sure completely how to set it up and what parts to buy. If there is a cheap way for cooling please tell me thank you.

A few more fans might make it a bit cooler at night, but not near 55F - to get that, you'll have to invest in a more expensive cooling device. 3 computer fans can get my setup to around 60-62F every night with the humidifier running.

You could do the cheap method and just pipe a window air conditioner into it during the night if you already have one on hand. Just remember to keep the humidifier running since air conditioners also act as de-humidifiers.

yup, that amount of temp drop needs an AC
