Most plants are picky when it comes to temperature. Although most species can tolerate slight dips in temperature (like those experienced at night in outdoor gardens), continuous exposure to temperatures that are either too hot or too cold will kill your plants or, at the very least, adversely affect crop yield.
Indoor gardening almost completely eliminates concerns about temperature from the equation because I’m assuming the inside temperature of your home remains relatively consistent.
There are a couple of temperature-related considerations that do affect indoor gardens.
Avoid putting your garden near objects that get extraordinarily hot (or cold for that matter). The oven, heaters and the air conditioner are all potential enemies of your plants.
Also keep your garden away from drafty windows and doors in the winter months. Constant bursts of cold air could stunt the growth of plants and significantly reduce yields.
