The Pros and Cons of Several Kinds of Grow Lights for Indoor Agriculture


T5 Fluorescent Grow Lights

Fluorescent tubes are measured by their distance across. Every “T” stands for one-eighth of an inch. A T5 tube is five-eighths of an inch in measurement, a T8 would be one inch in width, et cetera. T5s are best utilized amid the propagation phase of plants since they run cool.

Pros of T5 Fluorescent Grow Lights

  • Generally more affordable than different kinds of grow lights.
  • They emanate a light that covers a bigger zone than most kinds of grow lights.

Cons of T5 Fluorescent Grow Lights

  • Are not valuable during the vegetative phases of development.
  • Are not valuable during the blossoming stages.

High-Intensity Discharge Grow Lights

HIDs or High-intensity discharge lights are extensive bulbed systems that make light by igniting a gas inside the bulb. HIDs are accessible in two sorts: high weight sodium (HPS) and Metal halides (MH).

Pros of HID Grow Lights

  • HID knobs are always dimmable, which can be ideal to modify the measure of required light for a given area.
  • If utilizing a digital ballast, a wide range of HID bulbs can be utilized without changing the ballast.

Cons of HID Grow Lights

  • HID knobs heat up consistently and this can burn plants if not observed or taken proper care of when you put them into a grow room.
  • They require extra equipment to work, for example, a reflector and a ballast. Some HID ballast will just work HPS and some will just work MH, which means several ballasts might be needed.

Double-ended Lighting

Double-ended (DE) lighting is a sort of HID grow light that has recently been made popular in the market. It is a kind of HPS that is a tube and connects at two closures of a ballast. It is much like a fluorescent tube and is not screwed into a single “port” in a ballast.

Pros of DE Lighting in Grow Rooms

  • Double-ended lighting endures longer than single-ended. It likewise stays more efficiently longer. A 10,000-hour SE bulb may have lost a lot of its usefulness after achieving that point of reference, however, a DE one may be as much as 90% effective in the wake of attaining a similar age.
  • DE lighting tubes are more slender than SE knobs. The merit of this is that more light can get to the plants than with single-finished bulbs put at a similar length.

Cons of DE Lighting in Grow Rooms

  • Double-ended lighting can be hotter than single-finished lighting, which can prompt foliage burn.
  • Double-finished lighting can’t take air blowing specifically onto it, for example, from HAF fans or circulation fans. Contact with air impacts the nitrogen inside the knob and brings down the bulb’s effectiveness.

LED Grow Lights

The LED (Light-emitting diode) grow lights are also new in the realm of artificial lighting but is not new to several parts of the world. The advantages of utilizing LEDs are numerous, yet the real deterrent to changing over to them is the cost of purchasing them.

Pros of LED Grow Lights

  • The scope of color spectra accessible is quite wide and can be adjusted and customized relying upon the crop being grown and its current phase of growth.
  • There are numerous makers of LED lighting with an extensive variety of highlights and advantages.

Cons of LED Grow Lights

  • Purchasing LEDs are on the expensive side. They are normally way more expensive than other grow light alternatives.
  • Some LEDs, with an aim to reduce purchase cost, emit less light than several kinds of grow lights. This can simply be avoided if the LED light preferred is no less than 2.0 micromoles per watt of energy.
