Which Is Better, LED or High Pressure Sodium?

Light Spectrum and Plant Growth

The light spectrum emitted by grow lights plays a crucial role in plant development. HPS lights are known for their high-intensity yellow-orange light, which is beneficial during the flowering stage but less so during the vegetative stage. In contrast, Horticulture LED offer a customizable full spectrum, allowing growers to tailor the light output to the specific needs of their plants.

Modern Horticulture LED can be designed to emit a full spectrum of light, closely mimicking natural sunlight. This flexibility enables growers to optimize conditions for both vegetative growth and flowering, promoting healthier and more robust plants throughout their life cycle.

Heat Management

Heat management is another critical factor in choosing grow lights. HPS lights generate a significant amount of heat, which can create challenges in maintaining optimal growing conditions. Excessive heat can stress plants, increase water consumption, and necessitate additional cooling systems, leading to higher operational costs.

Horticulture LED produce far less heat, reducing the risk of heat stress and lowering the need for extensive cooling systems. This advantage not only helps in maintaining a stable growing environment but also contributes to overall cost savings in terms of energy and equipment.

Lifespan and Maintenance

The lifespan of grow lights is an important consideration for any horticultural operation. HPS lights typically have a lifespan of 10,000 to 24,000 hours, depending on usage and maintenance. In contrast, Horticulture LED can last between 50,000 to 100,000 hours. This extended lifespan translates to fewer replacements and lower maintenance costs, making LEDs a more cost-effective solution in the long run.

I prefer to use LED. What about you?

about a year and a half ago I would have told you how much I hated LEDs

after learning how to with grow them I like them a lot

be safe and grow well

I prefer the Sun :slight_smile:

But using LED lights can save more space and increase production capacity.

not sure how ?

maybe

I have never used anything but led but I know you just can’t beat the modern LEDs with the full spectrum array and you can run a LED roughly 700 Watts cranking for like 20 bucks a month if that can’t beat that

yeah definitely!

not here in New York

never used HIDs ?

everything has its place and its use

all the best and grow well

a single plant in a 30 inch by 30 inch 7 foot tall closet under a single 400 watt HPS

did a pound 2014

@dequilo Damn how much is your power ours is only 11 cents a kilowatt but I have solar so I do most of my light work during the day so basically my power is free as long as I don’t go over 8 KW an hour and I don’t use a lot at night our bill stays pretty small and we’re grandfathered in for 5 years for 5 cents a kilowatt because our solar back feeds into the grid
I did the calculating for the solar myself and added the grow room in when it was running full tilt plus a little to compensate for fluctuations :wink:
Pulled a pound and a half in my 3x3 about 2 years ago with two hlg 300 L’S in there which is a little over 500 watts 400 was my sweet spot though with a UVA added in

last time I looked it is 23 cents a kilowatt delivered

I am covering a 8 foot by 16 foot room with a 8 foot ceiling when I work inside

I was covering it with 4800 - 5500 watts of HIDs mixed MH/HPS

I have it covered with 1200 - 1500 watts of LEDs now

so I save some bucks when I work inside, now I am more of an outside grower

now as I can do 6 plant an not have Johnny Law jacking them

I hope to do 24 pounds off the six plants I am growing but we will see this is

42.8 N in New York

all the best and grow well
