Do I have Bad Room Syndrome?

Inexplicable poor plant health and vigor may be attributed to Building Related Symptoms (BRS). The quality of indoor air can significantly impact the well-being of both plants and humans. This article will explore the various factors that contribute to poor indoor air quality and suggest solutions for improving the environment for plants.

Impact of Household Materials on Indoor Air Quality​

Homes contain numerous materials designed to resist fading, abrasion, and time. Unfortunately, many of these materials emit toxic vapors at low concentrations, affecting indoor air quality. Some common sources of toxic vapors include:

• Fresh paint, lead paint or solder, and sealers
• Old or new carpets, flooring, and room fixtures

When installing new flooring or wall paneling, it is essential to vent the room thoroughly or remove any problematic materials. Growers should also consider removing plants from the area until the emissions subside.

Effects of HID Lighting on Flooring​

High-Intensity Discharge (HID) lighting can cause certain materials, such as linoleum, to emit vapors. It emphasizes the importance of proper lighting and temperature management in grow rooms.

Preparing a Grow Room​

To minimize the risk of poor plant health, it is advisable to remove most furniture and flooring before setting up a grow room. Inspect the room for green or black mold, particularly in corners and closets. Additionally, check ducting for mold and mildew, and seal central heating ducts if possible.

Importance of Ventilation​

Rooms with stagnant air are most susceptible to vapor buildup. Vapors tend to accumulate during "lights off" periods when ventilation is low or off. Ensuring continuous or periodic ventilation can significantly reduce fumes and improve indoor air quality.

Other Potential Problems​

• Use of non-fish-safe silicone
• PVC in irrigation systems
• Lead solder in old home plumbing
• Rotting insulation and asbestos
• Fusarium wilt

It is crucial to thoroughly check all factors contributing to poor plant health. Pre-testing a room with houseplants can be a helpful precautionary measure.

Frequently Asked Questions​

1. What is BRS? Building Related Symptoms (BRS) refers to the negative impact of indoor air quality on plant health and vigor due to various factors, including toxic vapors from household materials.
2. How do household materials affect indoor air quality? Many household materials, such as paint, flooring, and room fixtures, emit toxic vapors that can be harmful to both plants and humans.
3. What precautions can be taken when installing new flooring or wall paneling? Vent the room thoroughly, remove any problematic materials, or temporarily relocate plants from the area to minimize exposure to toxic vapors.
4. What steps can be taken to prepare a grow room and minimize BRS? Remove most furniture and flooring, inspect for mold and mildew, seal central heating ducts, and ensure proper ventilation.
5. Why is ventilation important in grow rooms? Ventilation helps to reduce the buildup of toxic vapors and improve indoor air quality, promoting healthier plant growth.
