My friend recently got into growing weed, and she sent me an email expressing her concern for pests attacking her plants. I wanted to help her out, but the internet is freaking full of conflicting advice that it’s challenging to know what to do (and there are a lot of assholes on the internet, too).
So here’s my take on how to prevent pests and mold on your weed plants.
Protect your Weed Plants from Pest and Mold
The first thing you’ll want to do is make sure that their environment isn’t conducive to pests or mold. Some things that may contribute to this are:
- Temperature: Too high of a temperature can cause your cannabis plants to dry out, which makes them more susceptible.
- Humidity: Humidity is like your plants’ best friend if you’re trying to grow mold.
- Poor airflow: A lack of airflow gives pests more places to hide and breeds humidity for mold growth
- Light leak: The light given off by your lights will attract insects. It’s better to use the darkest materials possible so that no light escapes
- Crowded conditions: gives pests more places to hide
- Lack of air: Air circulation around the plants themselves is also suitable for pest and mold growth, so be sure to keep your plants spaced in a way that they have plenty of airflows.
Now, let’s talk about some preventative measures to protect your weed plants.
Make sure you don’t use any known carcinogens pesticides and try not to use any pesticides at all. Instead, we’ll be focusing on ways to prevent pests by manipulating the environment and some nontoxic means of getting rid of them (just like with mold).
- Remove any dead leaves or branches from your weed plants. Pests love these spots because they’re dark, humid, and just the suitable environments for problems to breed.
- Keep your humidity down by simply increasing airflow. This is why it’s essential to keep your fans running 24/7, but be careful not to let too much wind hit your plants, so they don’t dry out. If you have a problem with high humidity where you live, consider using a dehumidifier in your grow room.
- Don’t leave any bowls out! Pests like to climb and hide in the leafy bits around the bowl of your bong or smoking apparatus. Ensure to clean it regularly (after every smoke session!) and wipe down anything that holds water.
- Keep your lights off during the night. Most pests are nocturnal, so if you keep your soft, gentle lights on all day and then soft, gentle moon-like light off during the night, problems will have a more challenging time finding their way around.
- Be very diligent about keeping an eye out for any insects that get in! Insects are much easier to eradicate when they’re still small.
- Clean up any spills or messes immediately, so your weed plants don’t spend any extra time in damp, humid environments.
Oh, and one last thing to protect your weed plants: keep the humidity way down during flowering! Most people have their fans on 24/7 to keep things ventilated but turn them off during flowering, which means you’ll want to be very careful not to let the room get too humid.
How many times do you need to water your plants every day?
Right, only once is enough. Can you answer this question for cannabis plants as well? Here are some interesting facts about these plants that might help better understand them.
- Cannabis sativa L. belongs to the family Cannabaceae, consisting of 2-3 genera and approximately 20 species. Of course, there are various subspecies, but the most common one is Cannabis sativa L. What does it mean for us? It means that all cannabis strains have common characteristics, they require a relatively low amount of resources, they have big green leaves, and so on. Let’s take a look at two particular examples – Indica and Sativa strains of marijuana:
- With Indica, the flowering stage is shorter, and their leaves are a darker green. On the other hand, Sativa strains have a more extended flowering period with giant light green leaves.
- For beginners who try growing marijuana for the first time, it’s essential to know that all these distinctive features will help determine whether your plant is an Indica or Sativa strain.
- The main reason cannabis plants get sick is related to the water conditions in your room. More precisely, it’s about pH balance which plays a massive role in growing vigorous, healthy cannabis plants outside of nature. Soil should have a 6-7 pH level because this range helps prevent insects from damaging roots’ tissue and keeps dirt moist at the same time.
What do you think happens when…
…you add nutrient solution to your soil with a pH different from the one mentioned above? It means that cannabis plant roots will be damaged because nutrients in that water won’t dissolve. So what’s going on here? There are three main points to consider:
- Cannabis plants can grow and survive for weeks with a small amount of water, but if water conditions aren’t right, your plant will start dying after 3-5 days. If you see signs such as drooping leaves or yellowing, it might mean something is wrong with your plant…
- Seeds should germinate around 24-36 hours after being inserted into moist soil. Ensure that the earth is well wet, then wait for seeds to sprout. After 3-5 days, your seedlings should be ready to transfer into bigger containers (up to a size of 5 gallons).
- Sexing cannabis plants is possible by the end of week 2. If you see another white pistil growing after the first one does, this means that your plant is female. Otherwise, it’s probably male or hermaphrodite, which isn’t good at all when it comes to marijuana production…
- Your goal when buying seeds is to grow healthy plants. Ones with excellent yield and a high level of THC in the buds. To achieve that, you need to mimic natural conditions in your room because it’s the safest way to grow Cannabis.
Remember that healthy plants result from good growing conditions, which you can easily reach if you pay attention to water pH and avoid using chemicals when adding nutrients to your soil.
Okay! That’s about it! Feel free to ask me any questions in the comments below, and I’ll do my best to answer them. And finally–remember that no matter what you do, your weed plants are going to need some love. If you spend too much time trying to fix things, you’re not spending enough time taking care of your plants 🙂
You got this.
