What are light sources at night?
Light sources include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that comes from them.
Is artificial light expensive?
Artificial light sources They are generally considered to be the least energy-efficient choice of electric lamp but are inexpensive, turn on instantly and come in a range of sizes and shapes.
Can plants survive in artificial light?
Researchers can successfully grow plants using only artificial light in growth chambers. But sunlight is best for most plants. It's generally more intense than artificial light, and it's pretty equally distributed among the different wavelengths that earthly plants have evolved to like best.
Which grow lights are best?

- They're earth-friendly. ...
- Fluorescent lights are more affordable, and may be a good choice if you're new to indoor gardening or grow just a few plants.
What's better led or HPS?
LEDs are far more efficient than HID lighting. Pound-for-pound — or rather kilowatt-for-kilowatt — they produce more light than HPS fixtures. ... Along with better electrical efficiency comes better efficacy. A tailored LED spectrum provides plants with what they need for increased growth on a per-kilowatt basis.
Can you use LED and HPS together?
Therefore, if you combine the already tested and true HPS luminaires with the more efficient LEDs, plants will be able to take and use wavelengths that they need (when they need them), while also providing radiant heat and diffuse light from the HPS luminaires in addition to being able to extend your light use with ...
Can you switch from LED to HPS?
You can switch but keep the HPS higher than normal for a bit to allow the plant to adjust from the lower W LED.
Is HPS full spectrum?
Metal halide conversion bulbs that operate on HPS ballasts or digital ballasts have the same type of full-spectrum output as standard MH bulbs and usually have the added benefit of a higher lumen rating.
Can you veg with LED flower with HPS?
You can switch or use all of them. I use 400W hps for flower, and a small 300/127W led for veg, when not testing a larger 900/380W LED.
WHAT LED is equivalent to 600W HPS?
Platinum P450 274W LED grow light
How many plants can grow under 600w HPS?
Also question is, how many plants can I grow under 600w HPS? Sixteen plants that are grown under a 600-watt HPS lamp could produce about 37.
Is HPS still the best?
HPS grow lights allows for quick growth, fat big sprouts/shoots and constant big yields. They effectively turn electricity into light, and they emit a type/color of light that promotes better budding. Despite all the latest types of lights, HPS lights are still the most commonly type of grow light used these days.
Which is hotter MH or HPS?
MH IS hotter than HPS. CFL's (up to a point) are cooler than HPS.
How much area does a 1000W HPS cover?
These lights range in power from 100 to 1000 watts. The 400 and 1000 watt lights are the most useful. A 1000 watt grow light can light up an area of about 7 feet square when the light is suspended 2 feet above the plants. A 400 watt light would work for an area of about 4 feet square.
How much electricity does a 1000W HPS use?
Wattage/Current For example, running a 1,000-watt HPS light with about 1,050 watts of actual power draw for 12 hours a day will consume 4,600 kilowatt-hours (kWh) a year.
