LED Grow Lights

There's no single magic number, it depends entirely on the light's power and the plant's stage. For seedlings, start with lower-power lights about 24-36 inches away. For vegetative growth, you can move them closer, maybe 12-24 inches. During flowering, powerful lights like a 100W LED grow light might need to be 18-24 inches away to avoid burning the tops. The best way to know for sure is to watch your plants. If leaves start to look bleached or brown at the tips, the light is too close. Start high and lower it a little each day until you find the sweet spot.

Red and blue lights target the two most critical wavelengths for photosynthesis, which is super efficient for plant growth and flowering. It's great for commercial setups where you're maximizing yield. A full spectrum LED grow light mimics natural sunlight, appearing white to our eyes. This makes it much easier to actually see your plants, check for pests, and enjoy their natural color. For houseplants and general indoor gardening, most people prefer full spectrum. We offer both, including LED panels, LED bulbs, and LED strips.

For hydroponics, you absolutely need lights rated for high humidity or direct splashes. The key is water resistance. We have a couple of IP65 waterproof grow LED lights that are perfect for this. They're sealed against moisture, so you don't have to worry about condensation or spray causing a short. 

Absolutely. A lot of our customers are serious DIYers. We sell the individual LED components for people building their own panels from scratch. A simpler DIY grow light project is using our horticulture light strips. You can cut them to length and stick them under shelves or build a custom frame. It gives you total control over the shape and size of your lighting.

Generally, no. One of the biggest advantages of LEDs over older HPS or metal halide bulbs is how little heat they put out. Our larger UFO and panel grow lights have built-in fans or substantial heat sinks to manage their own temperature. For LED grow light strips, as long as you have decent air circulation in the room, they don't require dedicated cooling. 

Your plants will tell you. Look at the leaves closest to the light. If the edges start to curl up, or if you see yellowing or white bleaching on the top leaves while the lower leaves look fine, that's a classic sign of light burn. It's different from a nutrient deficiency, which often shows up on older, lower leaves first. If you see signs of stress, just raise the light by 6-8 inches and watch the plant for a few days.

This depends on the plant and its growth stage. For vegetative growth—when the plant is focused on growing leaves and stems—16 to 18 hours of light per day is the standard. For flowering or fruiting plants like tomatoes or cannabis, you'll typically switch to a 12-hours-on, 12-hours-off cycle. That dark period is critical to trigger flowering. Seedlings and clones do well with 18-24 hours of light. Using a simple wall timer is the easiest way to keep this consistent.

LED grow light strips are the best choice for lighting long or unusually shaped areas. Think multi-level shelving for seedlings, vertical gardens, or lining the inside of a grow tent. You can get even coverage over a large surface area where a single bulb would create a bright spot in the middle and dim edges. Bulbs are simpler for a single houseplant on a table or a small cluster of pots. 

That's because the light is emitting very specific, narrow bands of red and blue light. Plants primarily use these two colors for photosynthesis, so it's a very efficient way to grow them. The light looks purple or pink to our eyes because we're not seeing the other colors of the spectrum. While it's great for the plants, it makes it hard to judge their health. That's why many people now prefer the best full spectrum grow lights, which appear white and let you see your plants' true colors.
