A LIGHT UP FOR HOMEGROWN CANNABIS   

Lighting can seem very strange and confusing when lighting out hydroponics growing. The idea of hydroponics in growing marijuana without the use of soil is not a new event. It is believed that one of the numerous wonders of the world, "The Hanging Gardens of Babylon", was created by applying hydroponic systems. 

On the other hand, the benefits obtained from fabricated light have only been throughout a sensibly short time. They are now easily possible in an affordable setup by advancing systems and knowledge in this area. But before that visit https://marijuanaseedsforsale.com/ for a wide selection of seeds to start with.

Lighting Apparatus  

To use a produced light in hydroponics requires several samples of kit

• Ballast - needed to control the current to the light fixture.
• A shade/reflector - this points the light to precisely where you want it to go.
• Lamp holder/socket - is typically included with the shade or glass you buy.
• A timer sets the light off and on and regulates the degree of light the cannabis gets.
• A bulb or lamp

These items of apparatus and tools are required free of what type of bulb you are using. There are various ones out ready on the market, from budget to expensive versions. The one you buy is defined by what marijuana strain and what space you are applying as your hydroponic garden. 

What is Light Intensity?

Light intensity fades with distance if you have a wide area for homegrown cannabis. You will plausibly need an augmented wattage of the lamp to allow light to get to the plant. Hence you can use more lamps. 

However, you have more extra heat generated with a higher-powered lamp, which can be disputing to control. That is why many auto-flowering seeds cultivators choose to use a lower-powered light. 

This type of lamp will create less heat and be managed much more leniently but used in a smaller area. It all depends on preference and what you are natural with. Some many posts and resources review the benefits and drawbacks of higher and lower-powered light. However, again, it all cooks fluff to user choice, open area, and the class of cannabis you are aiming to grow.

Artificial lights

Artificial light is manufactured, and mixed-light models provide off different colours. The scale runs from 0-100, with 100 being the best light at showing the object's actual colour is lit. 

For example, the lights used in our homes are usually tungsten incandescent lights, giving off a warm glow. These typically have a CRI of about 95, whereas metal halide lights have a CRI of around 80, which is in the bluish spectrum.

Thus they are usually used in the flowering of the cannabis cycle. The red light stimulates the plant cycle's reproductive phase, often producing better harvests of fruit and vegetables. Due to the poor CRI, the light can make the plants under them appear pale and unhealthy, but this is purely down to the colours in the morning.

Kinds of Lamp

There are three critical types of bulbs used in hydroponics. They are as follows:

The LED (Light Emitting Diode)

You could be querying why LED lights have not been considered as they are likewise on the market to buy and employ in hydroponic cannabis gardens. LED lights affirm to be more energy-efficient and transfer out less heat as opposed to other hydroponic lamps. However, they remain a comparably new technology and, as a result, have some concerns that need to smooth out. Many growers have had queries getting the same penetration of light with LEDs that other lamps can provide.

Metal Halide

A metal halide bulb produces light by passing electricity through a gaseous mixture of mercury and metal halides. It is a type of high-intensity discharge (HID) lamp and was developed in the 1960s.

The metal halides in the bulb improve the colour rendition of the light given out, which is particularly useful in growing marijuana. You may often see reference to the CRI (colour rendition index). This is a measure of the colours given off by artificial light compared to those found in daylight. Daylight displays a variety of colours throughout the day. It, therefore, gives the different types of light needed for plants to grow. 

It is essential to know that metal halide lights emit blue light when using hydroponics, as blue light is needed when your plants start to grow. The seedlings thrive in this spectrum of light as they mimic the light emitted during summer when outdoor plants begin to grow. 

Many refer to metal halide lights like the ones to use during the vegetative stage or growing cannabis. This is where the plants start to produce thick stems and large leaves, making tiny, dense plants that utilize the light more efficiently. When the plants have grown sufficiently and reached the stage for flowering, you need to change to a high-pressure sodium bulb.

High-Pressure Sodium

A high-pressure sodium lamp is again a type of high-intensity discharge light. Similar to the metal halide light, high-pressure sodium lights consist of a gas discharge lamp. However, they contain sodium instead of metal halides and give off a dark pink colour when first switched on. 

This changes when the light has warmed up to a pink/orange colour that is part of the red light spectrum. These lamps have a CRI of 25 and subsequently, if used alone in hydroponics, produce tall thin plants often described as "leggy". 

Side Notes

Both HID lights are combined with the metal halide used to start plant growth and the high-pressure sodium to produce the result. The only problem with using these two lights is the cost of equipment. 

Each of these lights requires a different ballast to regulate and control the current to the light. This can be costly, depending on how big your garden is and how many views you need. However, there are dual spectrum lights on the market that emit both types of light and therefore only require one ballast for your growing needs. 

This is probably the best one to use hydroponics, as the initial outlay is negligible. More advanced gardeners prefer the two separate bulbs to maximize the growth potential and not compromise with the dual spectrum lamp.
