Cannabis Pests and Molds

Whether you are growing marijuana seeds indoors or outdoors, you will find that most dangerous for your growth are pests and molds. Many times inexperienced growers buy cannabis seeds and waste it, because they do not take precautions to prevent pest and mold infestation and do not fight them properly. There are several kinds of pest that will attack cannabis, namely mites, thrips , white flies, and gnats . These are just the most dangerous pests that you can find in your growth. In the case of mold, most common types are botrytis and pythium.

The most common pest that you can find on marijuana plant are spider mites. These bugs are the nightmare of all growers, as they are hard to get rid of. The infestation comes from either not-sterilized soil or is brought from outdoor plants. Mites attack the leaves puncturing them , and nourish on the chlorophyll. You can detect that your plants are suffering from mites infestation if you see white or yellow spots on the leaves (most often under the leaves). In later stages of infestation it is easier to detect spider mites as they build small white webs around the leaf. If you want to kill the mites either use some pesticides or spray the plants with tobacco juice or neem oil.

Another pest that will reduce the growth of your pot weeds are thrips. They feed on leaves, just like mites, but the results are different. In the case of thrips you will see more regular marks which are white. Also, tiny black spots are indication of thrips infestation, as these are their excrements. The bugs reproduce really quickly and suck out the chlorophyll which destroys your plants . Because of that, fighting them with pesticides is not so efficient. It is better to use neem oil or ladybugs as they prey on thrips. If the infestation is in advanced stages use some biological solutions.

Next type of bugs are whiteflies. They are significantly larger than thrips or mites, so spotting them should be easier. They are as big as a pen tip (2 mm), white and with tiny wings. If you shake your plant a little bit than you should notice them flying around. They damage the plant just like mites, but additionally the lay eggs in the soil. If you want to get rid of them use some insecticidal soap regularly. Other more ecological option is to introduce special wasps into the growth environment. They are known as ichenuemon fly and are natural enemies of whiteflies. However, this process takes much longer.

The last pests worth mentioning are gnats. They attack the roots that spring up from marijuana seeds. These bugs live in humid environment and lay eggs on the soil. Gnats will feed on the roots and suck out nutrients from them, effectively lowering the growth rate of the plant. To destroy gnat infestation you should stir and heat the soil or apply neem oil, insecticidal soap or rotenone. There is also one good trick: put some potato slices on the soil, the gnat larvae will be attracted to it, so after 4 to 5 days just throw out the slices with the little gnats on them.

Besides bugs there are molds , which will also attack your plant and lead to reducing the yield you can get from weed seeds. The most common is botrytis, also known as gray mold. It attacks the biggest most developed buds and produce waste that lowers the power and appearance of your buds. Initially the fungus is white but later it changes to gray color. Botrytis firstly grows on some dying or wounded tissue like withered flower petals and then moves onto the plant. Besides treating your plant with some fungicides you should provide a good air circulation in your grow environment and appropriate heat. All this is done to lower the humidity level as molds develop in humid conditions.

The other most commonly seen mold is pythium. It attacks the root system or the lower parts of the stem. You can detect a pythium attack if see the stem turning brown. You should act then, as later on it will attack the root and things will be much more difficult to handle. Apart from wetness and humidity, this mold develops when the soil temperature is fluctuating. So keeping a stable soil temperature and controlling the humidity level will prevent pythium from growing. If you are attacked by this mold use some chemicals to solve the problem.

To sum up, growers should constantly monitor their plants and look for any changes that may indicate pest or mold infestation. On top of that they should look for any traces of them as fighting the problem earlier is more efficient. Generally you should not worry about mold or pest when you plant cannabis seeds, as they attack during later stages of the growth. However, keeping stable temperature and appropriate humidity level from the beginning is a good principle. Remember it is easy to buy marijuana seeds but growing it and protecting it from external dangers is a tedious, but rewarding task.
