Night time outdoors

50s is too low, if you have an option to bring them in, that is the best way to go... if the hassle is too great, they will survive but it'll likely hurt yield a bit if it is many days in a row.

The most beneficial temperature for your outdoor cannabis garden is considered anything between 10 degrees Celsius (50 Fahrenheit) to 30 degrees Celsius (85 Fahrenheit). But that doesn’t mean multiple nights or/and days with temperatures at 10 Celsius (50 Fahrenheit) are any good for your weed plants, in fact, not at all. It is simply acceptable for your green beauties to experience a few (up to 3-4) nights within those temperature rates, and not anything more than 5 days. Now, what you must absolutely stay away from is anything below 40 Fahrenheit (4 degrees Celsius). Such low temperature can damage the tissues of your plants almost immediately. Of course, your strain choice will play a huge role in determining the most suitable temperatures for your green beauties. For example, auto-flowering marijuana plants are very resistant to colds. That’s because this type of marijuana varieties are a fusion of Cannabis Sativa, Cannabis Indica and Cannabis Ruderalis. Cannabis Ruderalis is a native Russian kind of marijuana that is genetically capable of resisting cold temperatures and finishing early with flowering. And indeed, the time that your cannabis plants will require to finish their entire growth process is also extremely important for outdoor marijuana growers and sustaining the right temperatures. Thus, if you live in a geographic region with a very short summer (for example only a month or two), then you need to choose strains which will be able to mature within the time frame. Otherwise, you ought to think about covering your green beauties with a nylon/ polyethylene plastic installation, working similarly to the concept of a greenhouse, to keep them save from trouble. Some cannabis cultivators use simple heaters, such as gas patio heaters to keep their plants warm and cozy at night, as well, and this also does the trick. In the case of very hot hours, when the heat goes above 85 Fahrenheit (30 degrees), make sure to build a quick shadow for your green princesses. You can simply stick 4 pieces of wood forming a square around your garden and throw an old sheet in case of emergency. Hope this helps my friend! Happy growing! 👊
