Achieving healthy, thriving plants indoors depends heavily on setting up the right grow lights. Whether you're growing seedlings, houseplants, or edible gardens, CTT Light provides expert recommendations to ensure optimal plant growth.
Seedling Grow Lights
- 💡 Color Temperature: Use full-spectrum bulbs with a color temperature of 5,000-6,500 K to mimic natural sunlight, supporting strong seedling growth.
- 💡 Distance: Position seedlings about 15 cm below the light for adequate exposure. Pale, leggy seedlings often indicate insufficient light, so adjust the distance as needed.
- 💡 Light Cycle: Provide 14-16 hours of light per day to promote healthy seedling development.
Grow Lights for Indoor Plants
- 💡 Color Temperature: Choose bulbs tailored to the specific plant species to deliver the right spectrum of light.
- 💡 Distance: Maintain a distance of 30-60 cm between the plant leaves and the grow light for proper illumination.
- 💡 Light Cycle: Provide 8-14 hours of light daily, depending on the plant's needs. Short-day plants like poinsettias and Christmas cacti require at least 12 hours of darkness each day to bloom.
Grow Lights for Edible Indoor Gardens
- 💡 Color Temperature: Full-spectrum bulbs are ideal for overall plant health. Fruiting vegetables like tomatoes and citrus benefit from warm bulbs (2,500-3,000 K), while leafy greens thrive under cooler bulbs (6,000 K).
- 💡 Distance: Position grow lights 15-30 cm above vegetables and herbs for sufficient light intensity.
- 💡 Light Cycle: Leafy greens need 10-12 hours of light daily. Sun-loving herbs and fruiting plants, such as basil, tomatoes, and peppers, require 14-18 hours of light, making high-output LED grow lights an excellent option.
