Hopefully, you won’t be using this LED grow light to grow your illegal plants (or maybe legal depending on where you are and what licenses you have), but here’s a great way to keep your plants healthy full of artificial LED light by making LED grow lights!
Specialized grow lights that closely mimic the sun’s rays are a better solution, but you can get the same effect with special LEDs that are also brighter, cheaper and last far longer. These bulbs actually work best as a supplement to sunlight during the day; however, they’ll also provide enough light after dark to ensure that your plants get the 12 to 18 hours a day they need to thrive. We connected three inside a clear plastic tube, a “light spike” that you can stick right into the pot for direct exposure, and added a controller that adjusts the brightness. Or you can string together multiple spikes to cover several plants at once. The system should keep your plants in great shape until springtime—just don’t forget the water.
