Types of Grow Lights

How to use Grow lights is quite essential to know, but before that, what matters a lot. So, there are mainly three types of Grow lights that are used much.

Led Grow Lights

So, when you decide to do a Plantation in a large area, you can prefer LED Grow Lights without any second thought. They are reliable and produce very little heat that will be the safest and adaptable environment for the crops or plants you want to grow.

Fluorescent Grow Lights

A decent light bulb for your plants and cheaper than LED Grow Lights. These are used for small quantity plantation and specific plants individually. The best part of this is they come into bulb shapes and easily fit in a regular bulb socket.

If you do not want to have large fixtures and setups, Fluorescent Grow Lights is an option for sure.

They regulate the excellent weather of a specific plant as they have adequate light intensity required by a plant so that you can use them according to your convenience, even at small places and with no unique fixtures and sockets. These are the best for moderate light-seeking plants to grow naturally.

HID Grow Light

These Grow lights are also handy for large Plantation and well known before the LED Grow Lights come into the picture.

They are expensive than LED Grow lights but pertains well penetrating power for large scale crops. They consume more electricity, so not OK power efficient than the LED ones.

If you want to grow Tomatoes on a large Plantation, then HID Grow Lights is the best option as the light penetrates deep into the foliage than other Grow Lights.

This type of bulbs’ main drawback is that they need unique and large fixtures that can only be used and imposed in large areas and for large quantity crop plantation.

Types of HID Bulbs:

There are mainly two types of HID Bulbs

Metal Halide Bulbs

These bulbs are widely used for Vegetative Growth on a large scale, and these are labeled as MH bulbs. These are generally with High Spectrum.

High-Pressure Sodium Bulbs

These bulbs are widely used for Flowering plants, and these are labeled as HPS Bulbs.These have a Low Spectrum.  

The above categories are used as a conjunction; however, they also require their unique Fixtures. Though they are not of much power efficient bulbs, they are trendy and widely used, assuming they are power efficient and with good results.

How to install Grow Lights:

How to use the Grow lights has already been discussed in detail, so now, for installation, we need to have a better idea as installation requires unique fixtures, which depends on the quality and quantity of bulbs.

Construct a Rack

Proper construction of the rack is quite essential for the plant’s growth. They should be adjusted at an appropriate height for the proper growth of plants and your crops.

When plants grow to a definite height and level with time, the rack where the bulbs have been installed should be adjusted accordingly.

For this, you can use the chain method by which you hang your bulbs or use pulleys to adjust the height of bulbs from Plants.

You can create this installation on your own or purchase them online for better fixtures and adjustments.


Number of Bulbs Required

This is an essential factor in how much vegetation and Plantation need how many bulbs. The vegetation requires specific watt for the best results.

The crops like Tomato’s need more watts between 45-65 Watts for best results and other edible crops need less wattage between 25-30 Watts.  

Wattage information reflects on the label of the bulb. You can check while purchasing them.

Better to know about wattage per square foot required by specific crop, better the results.

You can calculate the total watts required per square foot by merely calculating the number of bulbs required to touch the desired watt range in a specific area of Plantation.

Add the Appropriate Timers

Plugin your bulbs and leave them as it is throughout the day is not wise. So, plug your bulbs in a manner that they give appropriate light at a particular point in time.

If the temperature rises above the specific level, then proper ventilation should also be installed.

To manage this as per its own, plug the bulbs as per the Timer so the light will be adequate at the same time of every day.  The low down according to the temperature rise and at full strength according to temperature falls.

Is There Any Time Frame the Grow Lights Should Be Turned on for?

How to use Grow Lights with proper timings is also very important. Never switch on the bulbs for an entire day. It may hinder the growth, and yield will not be up to the mark. It may lead to plants and crop damage as well.

As per the study, 16-17 hours of light is sufficient for edible crops to grow smoothly. 5-7 hours of darkness is also a significant factor for plants.

More light is needed when you grow something indoor than the one you grow outside, so proper timing of light is a crucial point of concern.

When plants grow to an appropriate height and level, you can fix the stand height accordingly, and the timing of light adjustment should also be checked.

Some Major Height Adjustments for the Best Yield:

  • Fluorescent Grow light bulbs: 4-13 inches
  • HID Grow light bulbs: 26-62 inches
  • LED Grow light bulbs: 14-25 inches
