In addition, every bulb has an independent on/off switch, allowing you to control the lighting duration in the same grow room. For example, short-day plants like chrysanthemums need under 12 hours of light daily, while long-day plants like lettuces or potatoes need 14 to 18 hours of light daily.

Plus, the full-spectrum option is for general cultivation. You should place these bulbs 12-18 inches away from your seedlings.

Plants need rest, just like humans, to transport nutrients into their extremities. That said, you should not leave grow lights on 24/7. But how can you adjust your artificial lighting system when you are not at home?

FAQs

1. What’s the difference between grow lights and regular lights?

Grow lights have some differences from standard LED lights, including higher heat emission, higher energy consumption, lower energy efficiency, a shorter lifespan.

Since these lights are designed to boost the growth of plants and flowers, they can spread light on the same wavelengths as natural sunlight. These lights are more affordable but harder to be found than regular lights.

2. What color grow light is best?

Blue is the best color for a grow light. This color can easily be absorbed by chlorophyll and converted into energy through photosynthesis.

3. Are purple grow lights better?

Although purple grow lights have a limited effect on plant growth when used standalone, you can combine them with red and blue ones to enhance the color, scent, and taste of plants.

4. How many lights do I need in my greenhouse?

For optimum growth, a greenhouse needs at least 6 hours of direct or full-spectrum light. If it can’t receive enough natural sunlight, you should use additional supplement lighting like grow lights.

5. What type of light is best for growing plants indoors?

Full-spectrum light is the best option for growing plants and flowers indoors. This light type provides the perfect balance of cool and warm light like the solar spectrum in nature.

6. What is the difference between red and blue LED grow lights?

Both red and blue LED grow lights are essential for the lush growth of plants, and these two lights should come together for the best plant growth.

But red lights are more important in the flowering stages of plants. They result in more robust development, more leaves (for veggies), better fruit quality (for fruit trees), or better bloom production (for flowers).

7. Should I leave a grow light on 24 hours?

You should not leave a grow light for 24 hours since all plants need darkness to rest. In the darkness, they take a break while transporting nutrients into their extremities.

My Top Pick

The best grow lights for greenhouses are essential supplements to missing sun rays, especially if you live in the North or have limited natural sunlight exposure in your indoor garden.

You can use these lamps to light up dark corners in your greenhouse to ensure equal lighting for all of your plants or turn on grow lights after sunset to give your plants extra light exposure for quick cultivation.

Yet, make sure you pick a high-quality item like Monios-L LED grow light strip. This light set is durable and energy-efficient and comes with all necessary accessories and tools for quick installation.
