T5 lights are great for helping your plants to grow. T5 lights are a type of fluorescent lighting, with the T indicating that they are tube style lights and the 5 indicating that the tubes are 5/8 of an inch in diameter and there are numerous types of T5 grow lights and grow light systems available on the market.
High output lights, such as T5 lighting, do not give off a lot of heat, so you are able to place them much closer to your plants then you would be able to do with traditional bulbs. This allows you to give your plants a higher level of light, which can help them grow and flourish. Also used for indoor growing, fluorescent lights help to mimic the light of the sun, and this is a help for getting those plants to grow as well.
You can also use T5 fluorescent lights for cultivating your seedlings or even for cloning. It is very important to make sure that you choose the right type of bulb for your needs in order to be successful, however. For growing vegetables, cultivating seedlings and cloning, you want to use bulbs that are in the blue light spectrum. If they say “cool white” then this should be sufficient for your needs.
T5 light fixtures and grow light systems using these type of high output bulbs will help you to see a larger growth with your vegetables and plants. Because T5 light bulbs do not put out a lot of heat, you are able to place them closer to the tops of any of the plants that you are growing. Usually keeping them one to 3 inches from the tops is good, but on the odd chance that they do touch the plants, no harm will be done to the plants. The lights should not burn the plants like traditional metal halide bulbs would.
The way T5 lights are typically set up for growing plants is that there are several bulbs lined up next to each other, although in some grow light systems, there is just a single T5 bulb suspended above the plants or two bulbs set up side by side. The best style of T5 bulbs to use in order to get the best growth are the long tubular ones. There are many types of lighting and bulb options available to the avid plant grower, however, so it is worth doing a bit of research and looking into what is going to work best for you and for your plants.
