  • During the day, keep your indoor cannabis plants turned off to let them cool. However, turn the lights back on at night until they appear dry.
  • If there is moisture on the leaves, remove it before turning the lights back on or moving the plants into direct sunlight.
  • Be sure to mix the solution thoroughly before using it.

The versatile spray can not only be used to wash vegetables, but also other garden flowers like zinnias, impatiens, squash and cucumbers.

Leaf Fungus and Soil Gnats

If you want to start, begin by cutting off some of the leaves on your cannabis plants that have been most affected.

How to Kill Bugs with Baking Soda?

Sodium bicarbonate can also keep various types of insects away, including sap-sucking caterpillars, carpenter ants, and silverfish.

Sap-sucking pests

To naturally repel pests, mix two tablespoons each of baking soda and organic soap with two cups of water. Be sure to use bio-degradable soap so as not to damage the surrounding area with harsh chemicals.

If you have young plants, begin by spraying them with a diluted solution. A more potent mix may damage the leaves if they appear weakened due to infestations. If you garden outdoors, spray your plants weekly or as needed—for instance, after rainfall. While indoor plants are being sprayed, make sure all lights are turned off first.

Caterpillars

To create the anti-caterpillar powder, mix together baking soda and regular flour in equal parts. Then, use a brush to apply the mixture directly onto the flowers or vegetables you want to protect. The caterpillars will eat it and die within several days. If they return later, simply repeat this process.

Other critters

How to Fix Other Plant Damage with Baking Soda?

Deposits can form on cannabis plants due to a variety of reasons, such as bad weather, excess nutrients or pesticides, and even construction work taking place nearby. This build-up can impede the plant’s key metabolic processes – including photosynthesis and transpiration – by causing a coating.
