When you decide to grow cannabis, you have to realize that you’re going to run into various problems along the way. It is rare for someone to grow a cannabis plant without experience some type of problem. As long as you remain calm and work diligently to fix that problem, you shouldn’t be able to restore the plant to perfect health. And, you shouldn’t have to worry about it decreasing your yield. One of the most common problems associated with cannabis plants is heat stress. This is a problem that you need to know about so you can identify the symptoms and fix it immediately.
What can you do about cannabis heat stress? Is it going to kill your plants? You’ll learn more about this subject below.
Understanding Heat Stress
First and foremost, you should learn about the basics of heat stress. What does it mean? Heat stress is a serious problem. It mainly impacts plants that are going to be grown outside. However, you may run into this problem when growing plants indoors too. Heat stress occurs when the temperature gets too high and the plant doesn’t receive enough water. The hot temperatures and heat are causing the plant to dry out. This makes them overheat and stress out. If your plants are too hot, you’ll need to remedy that problem immediately.
If you’re growing them outside, this will be more difficult to remedy. If you have an indoor grow operation, it’ll be an easier problem to fix. Cannabis plants can handle a wide array of temperatures. However, there is a fine line here. If you let the temperatures climb up to the 80s and 90s, there is a risk that you’re going to experience problems.
The Common Signs Of Heat Stress
It is wise to learn more about the common signs of heat stress. This is very important since you can remedy the problem easier if you diagnosis it quickly. Unfortunately, the signs of heat stress can easily be associated with other problems. So, you may have to eliminate other issues before you can be positive that you’re dealing with this issue. To determine if your plants are suffering from heat stress, you should look closely at the serrated leaves. Are they starting to curl upward? If so and there are not burns, there is a good chance that you’re dealing with heat stress and not light stress.
If you’ve already entered the flowering stage, you’ll want to look at the buds that are growing. Do the buds closest to your grow lights appear to be bleached or stretched? This is a sure sign that your plants are suffering from heat stress. This problem will also cause your plants to begin developing brown or yellow spots.
What Causes Heat Stress?
Identifying the cause of heat stress shouldn’t be too difficult. However, it may be tough to remedy. First, you should check the temperature in the room. If it too high, you’ll need to work diligently to decrease the temperature immediately. At the same time, you should check the soil. Cannabis plans may experience heat stress when they haven’t been watered often enough. These are the two main causes of heat stress and you should be able to fix these issues easily. Also, there might be a risk that the temperatures are too low.
How To Deal With Heat Stress Outside
Unfortunately, you’re going to have more trouble fixing this problem when growing outside. Are the temperatures too high or too low? You’ll want to find out immediately. If you’ve determined that the temperatures are getting too low at night, you should try using a heater to increase the temperatures. You need to ensure that the temperatures in the growing area remain 60 degrees at all times. This will ensure that your plants remain healthy. You should also take steps to ensure that the area is properly insulated.
If you’re dealing with temperatures that are too hot, you should try using a fan. You’ll also want to pay attention to the forecast in your area. By monitoring the weather report, you may be able to move your plants back inside when it gets too hot. If this is not possible, you’ll want to water the plants early in the morning and try to keep the roots cool. You can also increase the shaded area around the plants. Do your best to care for the outdoor plants so other problems do not occur.
Dealing With Heat Stress Inside
If you’re growing plants inside, you’ll find that it is much easier to rectify this problem. First, you’ll need to find out what is causing it. Does it have something to do with your lights being too low? If this is the case, you should raise the lights. This will reduce the heat placed on the plant and stop the problem immediately. If your grow room is too hot, you can try decreasing the temperature and using a fan. Also, make sure that the plants have plenty of water. Increasing circulation is one of the best ways to minimize heat and protect your plants.
Install a thermometer in the grow tent so you can monitor the temperature at all times. This will enable you to act quickly if the temperatures increase too much and your plants begin experiencing heat stress.
Prevent Heat Stress
Ultimately, it is best to prevent heat stress in the first place. Again, this will be much easier if you’re growing cannabis plants inside. All you have to do is install a thermometer and make sure that the temperatures remain below 90 degrees. If the temperatures climb above that, you’ll need to decrease it immediately. If you’re growing outside, you should consider keeping your plants in buckets so you can move them around when necessary. Otherwise, you need to do what you can to minimize the temperature. One way to do that is throw a canopy over the grow operation. This will ensure that the plants have plenty of shade so they can stay cool.
Also, be sure to water your plants sufficiently to avoid additional issues.
