4 Issues Cannabis Growers Deal With

4 Issues Cannabis Growers Deal With

Growing cannabis isn’t easy. In fact, growing great cannabis consistently is difficult for most. However, the issues growers face are widespread and much more common.

New growers face a lot of the same issues when they get into cannabis cultivation. But even experienced growers can face the same issues, especially when expanding. 

The fact is, the bigger your grow, the more problems you’ll likely have to deal with. From mold and mildew to clogged lines and broken timers, here are some of the most common issues growers deal with, and how to deal with them yourself.

Powdery Mildew

If you’ve been growing, you’ve probably already dealt with powdery mildew. For the lucky few that have avoided PM up to this point, powdery mildew is a fungal infection that destroys your plants.

PM thrives in warm environments, which makes your flower room a great spot to sprout its spores. The reason PM is so hated by growers is that it can’t be cured. Once your plant is infected, it must be destroyed. Then you need to spray down the rest of your plants with some fungicide to prevent the PM from spreading any further.

Luckily there are organic options for dealing with PM so you cannabis plants will still be consumable.


As long as plants exist, so will bugs that try to eat them. When it comes to cannabis specifically, the most common bugs growers encounter are aphids, mites, thrips and white flies. There are other bugs that can be problematic if you are an outdoor grower, like grasshoppers and crickets.

When it comes to bugs like mites, that are so small you can’t see any problem until your plants are affected, it is better to be proactive in the grow. The options for pesticides and insecticides are vast, but there is a select list of products you can use on cannabis. Keep in mind that the permitted products on the list don’t apply in all states. For example, some pesticides permitted in Colorado are not permitted in California.

Irrigation Issues

Irrigation issues normally plague growers who are producing on a larger scale and must use irrigation to compensate. While a drip irrigation system is extremely cost effective and efficient in the grow, one problem can throw off your entire system

Other issues that can arise in your irrigation are mold and mildew, which can do just as much damage to your plants.

One clog in your tubing that goes unchecked can result in the death of however many plants are down-line from that clog. And in a large scale operation, that can mean hundreds of plants. However with regular maintenance, checking your lines for clogs consistently, cleaning them out often, and timers and notification systems that you can set up, these problems can be easily avoided.

Environmental Control Issues

There is a small window of environmental settings that allows cannabis to thrive. Straying too far outside these climate requirements is detrimental for your plants. A lot of new growers will just throw some plants in their room and feed them, without much regard for the temperature or humidity of the room.

The easiest way, though an expensive option for the hobbyist or home grower, is to have an automated environmental control system. You can set up monitors that track your temperatures and humidity, and notify you when there is a fluctuation. Of course, if you don’t have a proper ventilation system or A/C and heat set up in your room, a controller won’t be of much use.

As long as plants are growing, bugs will try to eat them. Hand watering won’t always be efficient. Cold weather will damage your plants if not accounted for. These issues seem obvious, but a lot of people deal with them every day.

But you don’t need to break the bank and build out the next generation grow room to be efficient. There are plenty of DIY options for irrigation, as well as simple and easy to use pesticides that are also organic for use in cannabis. And you don’t need a high-tech environmental controller to stay on top of humidity.

If you’re willing to put the time and work in to save the money, you’ll be fine. Or if you got the change to spare, spend it wisely.
