As a cannabis home grower, finding natural and cost-effective ways to care for your plants is essential. DIY home grower sprays can be a valuable tool in maintaining the health and vitality of your cannabis crop. In this blog post, we will explore various homemade spray recipes using natural ingredients that address common issues such as pest infestations, mold prevention, and nutrient deficiencies. These DIY  pest control solutions offer a convenient and eco-friendly alternative to commercial products. Be sure not to apply anything within a few weeks of harvest or you could spoil the crop, make it smell nasty, or have residues on the flower nobody wants to smoke.

  1. Neem Oil Spray:
    Neem oil for plants is a popular organic pesticide known for its effectiveness against a wide range of pests. To make a neem oil spray, mix one teaspoon of neem oil, a few drops of liquid dish soap, and one quart of water. Shake well and spray the mixture onto the affected plants, focusing on the undersides of leaves where pests tend to hide. Repeat every one to two weeks, especially during the vegetative stage.
  2. Garlic Spray:
    Garlic is a natural insect repellent that can help keep pests away from your cannabis plants. To make a garlic spray, finely chop three to four cloves of garlic and steep them in one quart of hot water for 24 hours. Strain the liquid, add a few drops of liquid dish soap, and transfer it to a spray bottle. Apply the spray to the leaves and stems of the plants, concentrating on areas where insects are present or prone to attack. Repeat every week or as needed.
  3. Milk Spray:
    Milk can act as a natural antifungal spray, helping to prevent mold and mildew growth on cannabis plants. Dilute one part milk with nine parts water (e.g., 1 cup of milk to 9 cups of water) and mix well. Spray the solution onto the plants, ensuring thorough coverage. Use this spray during the vegetative stage or as a preventive measure when humidity levels are high.
  4. Compost Tea:
    Compost tea is a nutrient-rich spray that promotes healthy soil and plant growth. To make compost tea, fill a container with water and add a handful of compost or well-rotted organic matter. Let it steep for 24 to 48 hours, stirring occasionally. Strain the liquid and transfer it to a spray bottle. Use the compost tea to mist the leaves and soil of your plants, providing them with beneficial microorganisms and nutrients. Apply every two weeks during the vegetative stage.

DIY pest control home grower sprays offer natural and cost-effective solutions for cannabis home growers to maintain healthy and thriving plants. Neem oil, garlic, milk, and compost tea are just a few examples of homemade sprays that can help combat pests, prevent mold, and provide essential nutrients. Experiment with these recipes and adjust the ingredients to suit your plants’ specific needs. By utilizing these DIY methods, you can cultivate a vibrant and organic cannabis garden while minimizing your environmental impact.
