Managing Temp & Humidity in 60×50×104 cm Box with SF1000D During Late Summer

Lead the exhaust through a window box directly out the window and set the lighting to the night hours and the morning. If it goes over 28 degrees Celsius and the relative humidity falls below 55%, then you should work with an evaporative cooler. If the temperature and humidity rise, a split air conditioner helps a lot. Make sure to pay attention that especially Sativas often want a fairly high humidity (60-70%) and can handle heat better than an Indica or in very dry air.
