Some growers even use fluroescent grow lights such as the T5 successfully to flower their plants (if the plants are kept short/small enough through growth control methods).

If the temperature is under control they can be kept as close as an inch or two away.

T5 grow lights should be kept as close as possible without burning your plants.

Plants tend to drink more water in different stages of growth, but just like humans, they need more water the hotter your growroom gets. This is why you need to install a ventilation system if your grow lights make the room too hot, and why you need to closely monitor how much water the plants need by checking their soil humidity level every couple of days.

Many indoor growers are already familiar with the virtues of T5s, but even if you know your T5 fixtures and more or less know how they work, you might need help with some things, because specifics like color temperature, hanging height and light cycles might not be as easy to figure out.

You are almost ready to go—all that’s left is figuring out the right light cycles, and then you can turn on your lights and start growing. A light cycle refers to how many hours you keep the lights turned on for and for how many hours you leave your plants in the dark. Light cycles are used to simulate night and day. Outdoor plants get a certain amount of hours of light and dark to grow properly, and you need to simulate these conditions indoors, too.

The best height for a T5 grow light is about 6-8 in. above the plants, but you should increase that gap to 12 in. if your plants don’t like heat or they are in the seedling growth stage. If the T5 fixtures are at this height, the light from the bulbs will be intense enough and bright enough for plants, but the heat won’t be able to damage your plants. Some plants need less-intense light, so just monitor your plants and see what works for your indoor garden set-up.

Fixtures: When it comes to choosing a grow light fixture, there are a couple of things to think about. First is the size requirements for this grow light. There are more than a dozen size variations, so you need to figure out the size of your indoor garden and then fit the lights to your space. T5 grow lights typically come in two different lengths and around six different bulb configurations.

You are finally all set to turn on the lights and start growing, but there are a few words of caution before you begin, though. Since you are growing plants indoors and your growroom might be small, you need to watch not only how much water your plants need, but the temperature of the room the plants are in as well.

T5 fluorescent grow lights are energy efficient and provide consistent levels of light to all of the plants within their reach. Whether you’re already up and running with your T5 fixtures, or are just starting out, this article contains helpful advice.

Choosing the Right T5 Grow Lights

The most common T5 grow lights are 2- or 4-ft. long and have 1, 2, 4, 6, 8 or 12 bulbs per fixture. If you are thinking of growing only a few small plants, you might get away with having a 1- or 2-bulb set-up that is 2- or 4-ft. long, but if you want to grow a whole bunch of plants, you will have to invest in an 8- or 12-bulb set-up that is 4-ft. long. This larger size will cover a lot of plant mass without using too much electricity.

Considerably more efficient than their predecessors – the T8 and T12 bulbs – T5s boast a higher brightness output with less energy used per lumen produced. You can also find them in a high-output (HO) option that increases their brightness and efficiency even further.

Why Should I use T5 Grow Lights?

If used during the flowering phase, the maximum lumen capacity of HO-style T5 bulbs can lead to greater yields of a more potent and aromatic flower.

Downsides of T5 Grow Lights

Though they may be less energy efficient, T8 grow lights also produce less heat. Why would you want less heat? This becomes especially important during the early stages of your indoor growth.
