Can Gardenias Be Placed in the Bedroom?
The pure and fragrant gardenia is deeply loved by our people, but there is always controversy about whether such fragrant plants can be placed in the bedroom. This article will analyze the compatibility between gardenias and bedroom spaces from three dimensions: plant characteristics, human health, and maintenance needs.
One, the Safety of Placing Gardenias in the Bedroom
1.1 The Truth About Oxygen Consumption
Online rumors suggest that plants will compete with humans for oxygen at night, but in reality, the amount of oxygen consumed by gardenias throughout the night is only equivalent to 0.03% of indoor air. The concentration of carbon dioxide released at night (about 0.1‰) is much lower than that produced by human breathing (about 4%), well within safe limits.
1.2 Air Purification Characteristics
The leaves of gardenias can absorb volatile organic compounds such as formaldehyde and benzene, with a purification efficiency of 0.15mg/m³ per hour. The volatile aromatic substances released can also inhibit the growth of pathogenic bacteria like staphylococcus, combining ornamental and practical value.
Two, Analysis of Bedroom Environment Compatibility
2.1 Light Demand Matching
Gardenias require 4 hours of scattered light per day, and for north-facing bedrooms, it is recommended to place them within 1.5 meters from the window. Using LED grow lights (recommended wavelength 450-650nm) for 2 hours a day can maintain normal growth.
2.2 Key Points for Temperature and Humidity Control
The ideal growth temperature is between 18-25°C, and the relative humidity should be maintained at 60%-70%. During the winter heating season, it is recommended to use a humidifier to avoid leaf edge browning due to dryness.
Three, Taboos for Special Populations
3.1 People with Respiratory Sensitivity
The concentration of linalool released by a single plant in full bloom can reach 0.8mg/m³. It is recommended that asthma patients maintain a distance of more than 2 meters or choose double-petaled varieties (which reduce the aroma concentration by 40%).
3.2 Nighttime Placement Plan
During the flowering period, the plant can be moved to a well-ventilated area after 19:00. This can prevent the accumulation of aroma concentration (which can reach three times the daytime level in a closed space at night) and ensure normal photosynthesis for the plant.
In summary, placing gardenias in the bedroom should follow the three principles of 'choosing the variety, controlling the quantity, and frequent ventilation.' It is recommended to choose medium and small-sized potted plants no taller than 60cm, with no more than 2 pots in a single bedroom, and to open the windows for ventilation twice a day to balance health and ornamental needs.
