The heat per watt is far greater with an HPS fixture compared to LED. This technology is far more efficient in transferring energy in to light, as it produces less heat and has a higher wattage equivalency to HPS (600w vs 1000w).
Is HPS better than LED?
LEDs are much the same. Though they’re generally more efficient than HPS (with some clocking 2.8 µmol/joule), some LEDs are less efficient than high-quality HPS fixtures, and they give you less light.All too often, the µmol/joule rating on HPS products states the lamp efficiency, not the actual product efficiency.
WHAT LED is equivalent to a 1000w HPS?
Black Dog LED PhytoMAX-2 600
Despite the 600 in the name, this light is easily equivalent to 1000 watts of HPS power and is actually the most powerful fixture on this list.
Does HPS yield more than LED?
Higher Yields
A 600w HPS light can produce up to 150 to 300 grams in optimal growing environments, which is 0.5 grams per watt or less. LEDs, however, can produce as high as 1 to 1.5 grams per watt.Yet, they produce an equal light quality to that of a 600-watt HPS.
Why do commercial growers use HPS?
HPS bulbs provide an incredible amount of intense, raw light which lends itself to producing great yields. Because they’re older, HPS lights are more standardized among different manufacturers, making it a bit easier for growers to compare bulbs and set-ups.
Can I switching from HPS to LED during flowering?
LEDs Provide a Higher Quality Light Spectrum
There was a time when switching from MH to HPS bulbs between veg and flower counted as tailoring your light spectrum to your plants’ needs.When you switch from HPS to LED, your plants receive the blue hues they need for sturdy growth and root development.
Can LED replace HPS?
While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available.LEDs, however, are better able to control their light, which is why a lower-watt LED can replace a higher-watt high pressure sodium bulb.
Does more light equal more yield?
Because light really does equal yield, growers can compare their current flowering light levels to the 1,500 PAR target. Moving from 1,000 to 1,500 PAR offers upwards of a 33-percent yield boost.
How many plants can a 1000w LED light grow?
As such, it could provide solid coverage for up to 4 plants. Yield Lab 1000W HPS+MH Cool Hood Reflector Grow Light Kit (Price: $239.95) With a 1000w grow light, you’ll get 130,000 lumens from an HPS bulb and 110,000 lumens from an MH bulb. That’s sufficient to provide coverage for up to 6 plants.
How much does a 1000 watt LED yield?
The yield from a single 1000w lamp is about 2 lbs per harvest. For me, sometimes 1.5 Lbs and sometimes 2.25Lbs max. Each strain has different yields.
What LED lights do professional growers use?
HPS lights and T5 lights are used by the majority of growers (68% and 67%, respectively) during at least one growth stage, and LEDs are used by more than a quarter of cultivators.
Are LEDs brighter than HPS?
First of all, it is no question that LEDs are more efficient at creating light than an HPS lamp. LEDs will always beat HPS on a light meter But what we haven’t seen is the definitively better growth performance from LED grow lights, even at wattages that are nearly the same.
Can you use HPS for veg?
In response to the general question, can you use an HPS bulb for veg, the answer is yes. However I have pointed out better and more efficient ways to veg your plants.
Is HPS still the best?
Definitely. HPS lamps have driven the indoor cannabis cultivation industry for decades. They work and they work very well. While the top quality LED lights can now match, and perhaps even surpass, HPS lamps, many long-time marijuana growers still prefer the traditional lighting system.
Can you mix HPS and LED?
The way HPS lighting should be installed is so that the light overlaps so shadows are reduced, and light penetrates in a horizontal direction. Having a mix of both HPS and LED lighting provides an ideal distribution of both diffuse and directional light.
Is HPS good for flower?
Ironically, most HID grow light enthusiasts recommend using both MH and HPS grow lights. MH grow lights (metal halide) are suited best for vegetative growth and HPS grow lights are superior for flowering.
What LED grow light is equivalent to 600W HPS?
For example, the US-made Platinum P450 274W LED grow light (which is listed as equivalent to a 600W HPS) offers 11 bands ranging from ultraviolet to infrared.
Does Topping increase yield?
Does topping really increase yield. Some people claim topping does not actually increase yield, because the colas get smaller every time you top. But, it has been shown that the cumulative yield is much heavier when you top your plants. So yes, topping really increases yield.
Does longer veg time increase yield?
The longer you keep your plants in the vegetative stage, the bigger your plant will be, resulting in bigger yields from plants that were vegetated longer.I usually recommend a week of veg time for every gallon of growing medium (ie: a plant grown in a 5-gallon bucket should get about a 5 week veg).
How do I make my yields bigger?
For higher yields indoor, you want your plants to grow wide rather than tall. You want a bushier plant so more buds have access to direct light, rather than a long, lanky plant with several buds hidden under a canopy. By transferring your plants to larger containers, you can encourage more outward expansion.
How far should 1000 Watt HPS be from plants?
We have concluded that the ideal distance from plants for 1000w HPS should be around 20 to 36 inches. Whenever you purchase a new grow light, you can start with the recommended hanging distance and monitor your plants closely. You should back off the lights if you notice any bleaching of leaves.
