Sooner or later, every home florist faces the problem of reduced light levels during the cold period. The days get shorter, the sun rarely appears, and the light exposure of indoor pets decreases.
If normal daylight is not enough for plants in winter, you can compensate for it with artificial light. Using artificial lighting is an ideal way to grow or propagate plants in a room without windows. Fluorescent lights are indeed affordable and available in different styles with tubing or spot lamps. The tubing lights should be hung from the ceiling or a frame and will have a reflective background.
Conventional filament lamps are not suitable for this purpose: they are highly heated and can burn plants.
Artificial light bulbs have more ultraviolet, blue light, and less infrared light. Terrariums with lighting are a great option.
Gro-lux fluorescent bulbs are specially designed for indoor growing and emit a mixture of blue and red light spectrum's.
The hanging lamps should hang in the center of the plants so that the plants are not distorted. Wall lights are less practical in this regard. Household lights are not suitable artificial lighting and do not have the desired effect on indoor plants.
1. When creating optimal lighting conditions for indoor flowers, keep in mind the following
On sunny days, the temperature at south-facing windows rises a lot, and plants located there need to be watered often (but not at midday). Black plastic pots overheat the soil quickly; use ceramic pots for south-facing windows plants. You can also put dark pots in light-colored containers.
If you have a bottom-hung window or a vent, keep them open in the summer. Otherwise, hot air will stagnate.
1. You can prepare the shading in different ways: fabric, metal or paper blinds (be careful: metal blinds must not touch the plants, because they get very hot), you can frame them with a cloth overlay. Temporar options are newspaper or cardboard.
2. Choose energy-efficient LEDs or affordable fluorescents. LEDs (light-emitting diodes) create light when an electric current — a flow of electrons — passes through a special material called a semiconductor).
3. The distance from the plant to the lamp should be not less than 80 cm.
4. If the plants are grown exclusively under artificial light, the lamps should burn from 12 (for shade-loving species) up to 16 (for light-loving plants) hours per day
Arranging plants to sit in groups is a way of offering a varied amount of light to each plant. When taking care of flowers at home, do not forget to shade plants on the south window. This is where you can put more of your varieties if you turn the searing direct sunlight into a pleasantly diffused light. While most plants thrive in 12 - 14 hours of daylight each day, they also need their rest period which includes resting during the winter.
