Different types of lighting for growing hemp and details

[Grow]

There are different types of lighting for growing hemp. This is the most commonly used:
Discharge lamp (MH and HPS)led
Compact light
Neon lights
Plasma lamp and CMH lamp

1. MH and HPS lights



Advantages
The light transmittance of HPS lamp, the main advantage of discharge lamp is its high light transmittance. This allows them to even illuminate the secondary branches below the surface of the canopy. So far, no lamp can provide a light transmittance equivalent to that of a 1000-watt HPS bulb; on the other hand, their spectrum is particularly suitable for the needs of plants. The cool colors in the spectrum of MH or metal halide bulbs tend to be blue. This is exactly the conditions where the growing cannabis plant most needs to flourish. Finally, MH and HPS lamps are affordable.

Disadvantages
Discharge lamps generate a lot of heat. In winter in cold regions, this can help your growing room warm, but it can also cause serious heat problems in your growing room. Some growers who live in warm areas may not be able to grow indoors in summer, so you must equip yourself with a ventilation system that is strong enough to maintain a proper temperature in the closet.

Taking into account the fact that discharge lamps can become very hot, they are not suitable for small growth spaces. Indeed, we do not recommend using MH and HPS lamps in places with a space of less than 0.4 square meters (60 x 60 cm) and a height of less than one meter. .

2、Samsung LED Grow Lights for growing hemp
LED lights represent a major innovation in the field of indoor culture, the main reason: they significantly reduce energy consumption, but this is not all.

Advantages
It seems obvious that LED lights are energy-saving, but the biggest advantage of LED lights is their energy efficiency. In fact, compared with HPS, LED lights can reduce power consumption by 20% to 50%.



According to most manufacturers, the following is the equivalent relationship between LED and HPS:
120 Watt LED = 250 Watt HPS
270 Watt LED = 400 Watt HPS
480 Watt LED = 600 Watt HPS
700 Watt LED = 1000 Watt HPS

Therefore, eco farm LED lights are perfect for growers who want to reduce their energy footprint, and if you want to keep a low profile on your electricity bill, this is also a good choice. This will prevent you from arousing suspicion from the landlord or electricity supplier.

Another big advantage of LED is its spectrum, which is particularly suitable for the needs of cannabis plants, which is one of the things that reduces light output. This is because the LED spectrum of plants is better than that of discharge lamps. Finally, LEDs have the particularity of concentrating the direction of light flow to plants. This avoids light loss on the sides and above, and all light shines directly down on the plants.

Disadvantages
LED lights for cannabis cultivation are expensive
Okay, as you can imagine, all these benefits come at a price. The price of LED lights is particularly high. For full spectrum led grow light equivalent to 600 watt HPS lights, you will need to spend about 1,000 Euros. Therefore, it takes a lot of time to make this investment profitable. Even taking into account the energy saved.

3、Neon lights for indoor cannabis cultivation
For many years, neon lights have been the standard for horticultural lighting. They gradually gave way to more efficient lamp types such as MH and HPS bulbs.

Advantages
Low consumption, long life
Releases very little heat
Spectrum adaptation
A good solution for small spaces

Disadvantages
Not suitable for flowering period-no special neon lights can bloom,Must be placed very close to the plants and improved daily,With low light penetration, hemp plants can perfectly form buds and finish blooming under a neon light, but the harvest is disappointing compared to the blooming using another light

4. Other little-known garden lighting types: plasma lamp and CMH lamp

Plasma lamp
Plasma lamps have been used indoors since the 1980s, although they have been used since Nicolas Tesla invented the plasma lamps in 1890. As far as we know, only the Gavita brand offers plasma lamps. .

These lamps are very effective for the growth period. On the other hand, for flowering, it is recommended to use them in addition to HPS lamps. In fact, some growers often use HPS lamps in addition to plasma lamps. Even in the growth stage, this plasma/HPS combination is known for providing plants with a perfect growth and flowering spectrum.

Indoor Culture CMH Light
CMH (Ceramic Metal Halide) lamps are very similar to MH lamps. They are based on older technologies than MH and HPS, which have been re-used for horticultural applications. Their spectrum is more suitable for plant growth than HD. The manufacturer recommends using mixed bulbs (4100K) for growth and flowering.



Less heat, the most important thing is to reduce electricity bills. However, many cannabis growers still prefer to use HPS for large blooms.

The negative point of CMH lamp?
Their price, the bulb + ballast + mirror kit from Lumatek is about 380 €. Every time a lamp needs to be replaced, it costs 80 euros for every 5 to 8 sections.

It will be determined in the future whether CMH will replace HPS lights. If the manufacturer's promise is true, CMH may even cast a shadow on the LED.After understanding all the functions and advantages and disadvantages of each type of lamp, choose the best commercial led grow lights for indoor cannabis.
