You've tried growing indoor plants but have experienced limited success. No matter where you live, it is nearly impossible to achieve perfect growing conditions throughout the year. For indoor gardeners, a T5 fixture might be the ideal solution to remedy previous failures.

Indoor crops need sufficient lighting to thrive. Traditional light bulbs don't promote plant growth. Fluorescent lighting may be the solution to turn misfortune into success for indoor planting. T5 bulbs seem to fill a void in the grow light industry where traditional T8 and T12 fluorescent bulbs have failed.

About Harvesting / Cultivating

Many people want to grow herbs, plants, and crops year-round. In some regions, natural lighting isn't adequate. Also, excessive rain or poor growing conditions limit the success of outdoor gardening in some areas.

The solution to this issue is to use indoor grow lights to enhance indoor plants. Grow lights mimic natural, outdoor sunlight. This allows an indoor gardener to cultivate a garden successfully, no matter where they live.

Why Grow Lights Are Needed

Grow lights using T5 bulbs create almost perfect growing conditions for individual plants. While some crops and plants require direct sunlight, others require lighting from an angle. Some plants or crops grow best if they are under high-light settings for only a portion of the day. With outdoor crops and plants, there is no control over light/dark conditions. Grow lights allow a gardener the ability to control lighting conditions.

Grow lights allow a gardener to:

  • Mimic natural sunlight indoors
  • Create almost perfect growing conditions for plants and crops
  • Choose how much or little light plants are exposed to
  • Select the lumens, and light-rating that grow lights emit

What Are T5 Fixtures?

A T5 fixture is a fluorescent light fixture that is fast becoming a favorite for gardening in an indoor setting. T5 fixtures come in various lengths, to support from one to four bulbs. Grow lights work using a specific light spectrum to promote vegetative growth, and the T5 bulbs fit this use very well.

Why Choose Fluorescent Lighting?

Fluorescent lighting is possible because of a chemical process. Gases and mercury vapor interact to produce powerful UV-lighting. The process results in a "white light" inside of the bulbs, rather than the subdued lighting traditional light bulbs emit.

The ballast controls the fluorescent bulbs. Bulbs contain inert gases, the ballast generates a low amount of heat, which causes the gases to react. The reaction produces light. The ballast also stabilizes the bulb and controls output. Fluorescent lights won't damage crops and plants and they are more energy efficient than traditional lighting options.

Choosing The Best T5 Fixtures

Before selecting a fluorescent fixture, it is important to compare several models. Indoor growers should understand the lumen and power output, and how to set up their lights. There are a few factors you should consider when choosing a T5 fixture for indoor gardening. Most T5 fixtures can be mounted horizontally or vertically, increasing their versatility.

Space Coverage

Most fixtures are available in 2-foot up to 8-foot-long frames. If you are in a small apartment, a single-bulb, 2-foot-long fixture might be perfect. However, if you have plenty of room, you might choose a more prominent fixture. The size of the coverage area determines the size of fixture needed.

Crops You're Growing

The vegetables and plants you're growing also impact lighting decisions. Overly powerful fixtures emit higher reflection levels which might kill plants. Likewise, a fixture without enough power will limit a garden's potential. Understanding how the lighting will affect your specific plants will aid in decision making.

Development Stage

T5 lights are best for getting seedlings to begin to grow. The T5 bulb is a blue spectrum light so that it can support plants through the initial vegetative process. Older plants might require more advanced spectrum lighting for maximum indoor growth.

Pros / Cons Of Using T5 Fixture

There are positives and negatives associated with using T5 bulbs for indoor growing. It is essential to understand how they operate for maximum results.

T5 bulbs are excellent in some growing conditions but not in others. Some of the pros of using these fixtures include:

  • Most emit low levels of radiant heat
  • You can control bulb output
  • They support early plant growth and development
  • Some fixtures work on a timer
  • arrow-right
    You can mount them vertically or horizontally

There are some cons gardeners should be aware of before using T5 fixtures. Some of these drawbacks include:

  • Aluminum housings for many of these fixtures aren't as durable as other materials
  • Quick burnout rate with T5 bulbs is a common complaint
  • They are best for the vegetative state, meaning you'll only use them for a short period of growth time
  • Some units heat up quickly and might require a fan or other ventilation to prevent overheating
