Temperature control

I like Spuwuky's idea for an evaporative water cooler - but yes, that WILL raise the humidity. Summertime growing is a trial whether you're growing outdoors or in a tent! I don't know where your tents are located but if you've got MULTIPLE tents, I would set an a/c up in the room they're in (essentially in their lung room) - not inside the tents themselves... when you cool down the lung room, there will be a much better shot at controlling the temps inside the tents.... cool air is brought in from the cool room, etc... Good luck!

High Valleywestbuds, If the temperatures do not exceed 30 °C I would just change the times that the lights are on. Put then on at night and switch them off by day. If it is hotter then 30 °C and you really want to know the best advice what kind of AC you should purchace then read this article: https://hydrobuilder.com/learn/beginners-guide-choosing-sizing-acs/ Happy Growing! 😋

In my 4x4 AC Infinity, I have - 3 Monkey Fans - 2 Humidifiers (One is not enough to get above 60% humidity where I live) - A standing oscillating evaporative water cooler. The evaporative water cooler is basically a fan that blows air through water pads. You can fill it up with ice water and it will help bring your tent temps down, but can also raise humidity. I vent into the room directly and have a dehumidifier running to keep the room at 55% max at all times so I can pull in lower humidity air if I need to drop it, but since you're having heat problems I would recommend venting out a window or into another room so that you're not pulling in that hot air again.
