Cold and cannabis, it’s a bit of a love-hate relationship. On one hand, cold can be the pesky villain, causing stunted growth, wilting, and even the death of your precious plants.

So how does the cold actually affect your green buddies? Well, it’s all about the roots. When the soil gets too cold, it can make it hard for the roots to uptake nutrients.

Indoor growing is a splendid way to keep your cannabis snug as a bug in a rug. To keep the chill at bay, you’ll want to maintain a constant temperature around 70-85°F (20-30°C) during the day, and a little cooler at night. Insulate your growing room, and use heaters or heat mats if needed. But remember, don’t turn your grow room into a sauna. Too much heat can make your cannabis sweat, and not in a good way!
