Defy Winter – Grow Plants.
Winter in the northeast means closing up doors and windows and spending most of our time inside. I miss fresh flowers and my garden. There are lots of ‘Grow Lights’ which produce light with the same wavelength as the sun and give indoor plants the ‘sunlight’ they need to thrive.
Plants need 10 to 16 hours of sunlight – remember photosynthesis? This is why gardens are happiest in the long, lazy days of summer. There are fewer hours of daylight in winter and even plants in warm windows do not get enough energy to grow healthy leaves, flowers and fruit. If your indoor plant is tall and spindly with small leaves and thin stems, it is not getting enough light. The leaves may be lighter than they are in the summer.
Mid-winter, I am especially interested in creating the right environment to encourage orchids which have flowered, to thrive and flower again. Most orchid plants should be placed 6 to 8 inches below the grow light and be in the light for 14 to 16 hours each day. Saving one or two special orchids will more than pay for the grow lights listed below.
There are four types of grow lights.
- Incandescent lights are the least expensive, but they are not very effective at reproducing the wavelengths of sunlight. The bulb gets hot, so they must be placed a distance from the plant.
- LED lights have been said to produce little useable light for plants, but they are cool. There is a new generation of LED lights which get great reviews.
- Fluorescent Lights are adequate for your indoor herb garden, but they do not give enough light for flowering plants.
- Compact Fluorescent Indoor Plant Lights are newer, brighter, smaller, cooler and more energy efficient than regular fluorescent lights. Plants can be placed close to them to maximize the light they receive.
- High Intensity Discharge Bulbs (HID) are both bright and high efficiency. They are relatively expensive.
All light is not created equal for plants.
- Blue-white light is good for leaves and keeps plants from getting spindly. Metal Halide Bulbs (MH) produce blue-white color.
- Red-orange light is best for flowering plants, but is not the best for leaves.
