Advantages of Indoor Growing:

When you grow cannabis indoors, you have control over everything–like the weather and the light. It's like creating the perfect space for your plants. But, if you don't prevent pests, they can still find a way in and cause trouble. Indoor growing gives cultivators the upper hand by providing a closed environment where factors like temperature, humidity, and light can be finely tuned. However, even with these advantages, pests can be persistent, making prevention crucial for a successful harvest.


Inspections and Rules:

In many places, cannabis growing facilities need to be checked for pests. For example, in Los Angeles, the rules say that facilities should always be built and operated to stop animals and bugs from getting in. If there are signs of pests, the facility needs to close, get professional pest control, clean up, and then reopen. Government regulations emphasize the importance of maintaining a clean and pest-free environment to ensure the quality and safety of cannabis products. Regular inspections are carried out to catch any signs of pests or vermin, and strict measures are in place to address and eliminate infestations promptly.


Keeping Grow Rooms Clean:

The first step to prevent pests is to keep your grow rooms clean. If your growing space is dirty, pests find it easy to sneak in and destroy your harvest. Air filtration systems, like CleanLeaf, can help keep your plants safe by keeping the air clean. A clean grow room is the foundation of successful pest prevention. Regular cleaning, proper waste disposal, and maintaining overall hygiene create an inhospitable environment for pests. Air filtration systems, such as CleanLeaf, play a crucial role in purifying the air and protecting plants from potential threats.

To deal with them, move infested plants outside, remove heavily infected leaves and buds, and use insecticidal soaps, neem oil, Spinosad, or Essentria IC3. Aphids, being one of the most common cannabis pests, can vary in color and shape. They damage plants by feeding on their juices. Prevention involves identifying their presence early, removing heavily infested parts, and using various treatments like insecticidal soaps and oils.
2. Barnacles:
Barnacles are scale insects that can look different in colors and patterns. To tackle them, spray off bugs, and use insecticidal soaps, neem oil, Spinosad, or Essentria IC3. Scale insects, known as barnacles, can infest plants and cause significant damage. Effective prevention includes regular inspections, physical removal of bugs, and the use of natural remedies like neem oil and insecticidal soaps.
3. Broad Mites:
Broad mites are very small and hard to see. They cause twisted, blistered new growth. To manage them, use neem oil, Essentria IC3, insecticidal soaps, Mighty Wash, Avid, Forbid, Diatomaceous Earth, or heat. Broad mites are a challenging pest to detect because of their size. Prevention involves a combination of treatments like neem oil, insecticidal soaps, and heat control to avoid infestations.
4. Caterpillars, Inchworms, and Loopers:
Caterpillars have many legs, loopers have two sets of feet, and inchworms have three pairs of front legs. To address them, use BT Spray or Spinosad. Shake plants to make worms fall out. These worms can damage leaves, buds, stalks, and the main stem. Prevention focuses on early identification and treatment with solutions like BT Spray and Spinosad.
5. Fungus Gnats:
Fungus gnat larvae are hard to see, and adults are gray to black. To control them, let the top inch of soil dry before watering, use Neem oil, apply Diatomaceous Earth, or use yellow sticky traps. Fungus gnats are common in over-watered conditions. Prevention includes proper watering practices, the use of natural remedies like Neem oil and Diatomaceous Earth, and employing traps.
6. Leaf Miners:
Leaf miners are larvae that live inside leaves and tunnel through them. To handle them, use environmental control, remove affected leaves, and use Spinosad, Neem oil, or BT spray. Leaf miners cause damage by tunneling through leaves. Prevention involves maintaining. environmental control, removing affected leaves, and applying treatments like Spinosad and Neem oil.
7. Spider Mites:
Spider mites are very tiny and cause yellow, orange, or white speckles on leaves. To manage them, control heat, blow air over plants, use Mighty Wash, neem oil, Spinosad, Essentria IC3, insecticidal soaps, or Diatomaceous Earth. Spider mites are challenging because of their small size. Prevention includes temperature control, air circulation, and treatments like neem oil and Spinosad.
8. Thrips:
Thrips are small, almost any color, and damage leaves by leaving shiny spots. To deal with them, use insecticidal soaps, neem oil, or Spinosad. Thrips cause damage by sucking out plant juices. Prevention includes using treatments like insecticidal soaps and neem oil.
9. Whiteflies:
Whiteflies steal nutrients from underneath leaves. To handle them, use insecticidal soaps, neem oil, Spinosad, or Essentria IC3. Whiteflies can weaken plants. Prevention involves the use of insecticidal soaps, neem oil, and other treatments.


Methods for Preventing and Treating Pests:

  • Move plants outside and spray off bugs.
  • Use Avid (not during flowering), BT Spray, Diatomaceous Earth, Essentria IC3, Forbid (not too much), heat (careful with plants), insecticidal soaps, Mighty Wash, Neem oil, or Spinosad.
