How high should you have your quantum boards from your seedlings?

 Lots more growers are starting to use grow lights, especially LED grow lights, but there's a lot of confusion about exactly how to use them. One of the most common questions about using full spectrum LED grow lights is how far they should be from plants.

In general, LED grow lights should be 12-30 inches from the tops of plants. As plants grow, you'll adjust your lights to maintain a consistent distance from the plants. However, the distance will vary depending on the wattage of your lights, the type of plant, and the amount of ambient light.

LED Quantum Boards Placement For Seedling Stage
Seedlings need the least intensity and most distance between the canopy and the lights. You may have the instinct to blast these little guys with high-intensity light to promote fast growth. The truth is, they’re young, vulnerable, and likelier to thrive with a gentler approach. You should pay attention to the height with quantum board led grow light. 

Advantages of LED grow lights

LED lights should be used for indoor gardening because they're energy efficient, easy to install, have a longer lifespan than other lights, and produce less heat than other lights.

Compared to other lights--like high pressure sodium lights, metal halide lights, incandescent lights, and high-intensity discharge lights--LED have a lot of benefits.

For starters, LED lights last way longer--typically around 10 years or 50,000 hours. That's tremendously long, considering the fact that other types of lights might burn out within just a few months or a year.

Another huge plus to using LED lights is their minimal energy consumption. Even if you're not a tree-hugging, granola-eating hippie, that minimal energy consumption means that LEDs will cost you far less than any other type of light.

Let's stack on another benefit to using LED grow lights: Since LED lights produce less heat, you can put them closer to your plants. They can be placed between 12-30 inches above the plants and have a low probability of burning the plants.

Speaking of stacking: since you only need 12-30 inches of space between an LED light & your plant, you can stack shelves of plants & lights vertically, doubling, tripling, or even quadrupling the amount you can grow from each square foot of floor space.

 How Long Should the Grow Light Be Left On?

Different types of plants need different amounts of light. As a general rule of thumb, most vegetables and flowering plants need 12 to 16 hours of light per day, with flowering plants at the top end of that range. Plan on giving most plants at least 8 hours of darkness per day.

Darkness is actually very important for the plant growth cycle. During the day, sunlight helps plants produce energy through photosynthesis. At night, however, plants break this energy down for growth and flowering in a process called “respiration”.

Check your seed packaging or plant tags, or ask at the nursery for specific suggestions. And make sure you turn your grow lights off every once in a while. No one likes to work 24 hours a day – even plants!

 Setting Up an Indoor Plant Growing Area

How do you get sufficient light for houseplants and indoor garden areas? Here are 3 tips on how to best set up your space.

• Consider your indoor garden plot. Whether it’s a single shelf, a basement area, or an entire room, look at how much space you have. Pot plants and beddings accordingly.


• Depending on the type of plant, group the pots or trays 4 to 8 inches apart to allow for growth and easy access for pruning and care.


• You’ll also want to make sure you purchase lights that will illuminate your entire plantings area. You may need more than one bulb or light source to fully cover your growing area. Depending on the size, you may only need to use only one light for houseplants, or you may need more.

 Why your seedlings aren’t getting enough light?

Light is the number one underestimated factor of growing, even at the seedling stage. If seedlings don’t have enough light, they grow more slowly and can become leggy. Overall, growers who do not give seedlings enough light have longer crop timelines and higher rates of seedling mortality. 

Why do growers mistake the level of seedling light? 

• They don’t have enough lighting.


• They place lighting too far from seedlings (bad coverage).


• They don’t leave lights on long enough.  

Usually, these problems are easy to fix: add lights or adjust your seedling light schedules!

Indoor gardening has never been easier. Grow lights for indoor plants allow you to cultivate a wide variety of plants at any climate during any time of year. LED growing lights are specially designed to substitute natural sunlight, stimulating photosynthesis and providing the right color spectrum where the plant can grow and flourish. With the right fixture or bulb, you can have delicious tomatoes in the dead of winter or award-winning violets year-round.
