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

For optimal results, for vegetative growth choose fluorescent light bulbs that are labeled either as "Cool White" or "Cool" colored (also labeled as "6500k" colored).

Any part of the plant that is further away then 1-2 feet from the fluorescent grow lights is not getting an optimum amount of light, especially in the flowering stage when plants need a lot of light to produce buds.

However, you can use either type of lights during either stage and still get good results. People also use "Daylight" (5000K) bulbs with success.

There are many different levels of fluorescent grow lights including the T5, the T8 and the T12. I strongly suggest sticking with the T5 style of fluorescent grow lights for cannabis because they give off the most amount of light for the size, and are specifically designed to be able to support taller plants up to 24 inches.

Note: Some growers may have heard of “Induction” grow lights, which are pretty rare these days but still pop up from time to time. There are two types: “Magnetic Induction” grow lights do okay for growing cannabis but they’re pretty much glorified fluorescent lights. “Plasma Induction” grow lights actually perform pretty poorly at growing cannabis.

Fluorescent Lamp Cons

T5s, meanwhile, get their name from their tube shape and 5/8” diameter. T5 bulbs usually come in a set, where multiple tubes are placed side by side in a panel. As a result of this set-up, T5s provide more even light coverage. You’ll need to hang T5s from a fixture, but don’t worry, as they’re often very cool and won’t cause heat damage.

Another great thing about CFLs is that they can be positioned in innovative ways. Some people place them horizontally, while others dangle them vertically over the plants. Since they can fit into a small space, they’re pretty good for stealth growing.

CFL vs. T5 Tube Fluorescent Bulbs

The type you choose is really up to you and the size of your grow room – T5s might work better in a slightly larger space. Either way, fluorescent bulbs are not as powerful as other lighting types. As a result, they are best for small grow rooms with only a few plants. Cultivating on a larger scale requires the use of HIDs or LEDs, for example.

Please note that this bulb is not the best on the market. However, it is cheap and will do the job in the smallest grow tents.

There’s a lot to learn when you enter the world of marijuana growing. Newbies are confronted with a vast wealth of information and a steep learning curve. You need to learn about watering, feeding, pruning, and more. But before you even begin to grow your cannabis plants, you need a set-up.

Other Types of Lights

T5s are the preferred fluorescent bulb of choice for more experienced growers. However, CFLs definitely work, too. Bear in mind that you’ll have to put up with a smaller yield with both types of fluorescent lighting.
