## Abstract

The present invention provides an effective pest control solution for indoor cannabis applications. The interior atmosphere is controlled to expose the live cannabis plants or post-harvest plant products to low oxygen levels (higher than 1% but lower than ambient air) and high carbon dioxide levels for one or more periods of less than 48 hours. This combination is effective to prevent or eliminate pests without harming the plants.

## Claims

### Claim 1

A method of controlling pests in an airtight indoor space, the method comprising:
maintaining, during a consecutive period of treatment, a controlled atmosphere inside the airtight indoor space comprising a carbon dioxide concentration of 5%, an oxygen concentration of 5%, and a nitrogen concentration of 90%;
wherein the relative humidity of atmosphere inside the airtight indoor space is 10% during the treatment, and wherein the consecutive period of treatment is 1 hour.

### Claim 2

A method of controlling pests in an airtight indoor space, the method comprising:
maintaining, during a consecutive period of treatment, a controlled atmosphere inside the airtight indoor space comprising a carbon dioxide concentration of 5%, an oxygen concentration of 5%, and a nitrogen concentration of 90%;
wherein the temperature of the atmosphere inside the airtight indoor space is 10° C. during the treatment, and wherein the consecutive period of treatment is 1 hour.

### Claim 3

A method of controlling pests in an airtight indoor space containing living plants, the method comprising:
maintaining, during a consecutive period of treatment, a controlled atmosphere inside the airtight indoor space comprising a carbon dioxide concentration between 20% and 40% and an oxygen concentration between 0.5% and 5%, a remainder of which being nitrogen,
wherein the consecutive period of treatment is between 12 and 24 hours.

### Claim 4 (depends on 3)

The method of claim 3, wherein the oxygen concentration is greater than 1%.

### Claim 5 (depends on 3)

The method of claim 3, wherein the nitrogen concentration is about 70%.

### Claim 6 (depends on 3)

The method of claim 3, wherein the carbon dioxide concentration is about 25%.

### Claim 7 (depends on 3)

The method of claim 3, further comprising turning on a controllable light source within the airtight indoor space during at least a portion of the consecutive period of treatment.

### Claim 8 (depends on 3)

The method of claim 3, further comprising turning off a controllable light source within the airtight indoor space during at least a portion of the consecutive period of treatment.

### Claim 9 (depends on 3)

The method of claim 3, wherein the living plants are cannabis plants.

### Claim 10 (depends on 3)

The method of claim 3, wherein a maximum air leak tolerance inside the airtight indoor space is 0.15 cm2 per 100 m3 of volume of air.

### Claim 11 (depends on 3)

The method of claim 3, further comprising watering regularly the plants during the period of treatment.
