How much area does a 400 watt HPS cover?
How much area does a 400 watt HPS cover?
around 16 square feet
400-Watt HPS grow lights are the most commonly used HPS grow bulb, covering around 16 square feet and capable of producing high yields. 600-Watt HPS grow lights are the most efficient HPS grow lamp. 600W HPS grow lights produce more light output per Watt used than other wattages and cover around 36 square feet.
How many plants can a 400W HPS grow?
Yield Lab 400W HPS+MH Air Cool Hood Reflector Grow Light Kit (Price: $189.95) — A 400w HPS light provides 55,000 lumens, while a 400w MH light generates 36,000 lumens. This light intensity is enough to provide coverage for 1 to 2 plants.
How far should HPS light be from plants?
HPS lights should not be placed inches from the plants, as you would place fluorescent lights; you should set HPS lamps higher, generally between 5 and 8 feet from the plants. Whether you have a reflector with your HPS light makes a difference for how close you can keep it from the plants.
How much does a 400W HPS yield?
Best marijuana yield indoors In theory, the math is simple. 400 watts of an HPS grow light could lead to 400 grams (14 ounces) of weed at the end of the day. 1200 watts would lead to 1.2 kilos (42 ounces) of marijuana, etc.
Can you use HPS for the whole grow?
While either type can be used for the full growing cycle, when combined, using an MH grow light for vegetative growth and flowering under an HPS grow light is the most recommended HID grow light setup because utilizing the strengths of both types at the right times produces the best results.
Whats better HPS or LED grow lights?
LED grow lights are more energy efficient. They produce the same amount of light as HPS lights but consume substantially less energy. LED grow lights do not produce as much heat as HPS lights, avoiding the need for additional ventilation or airflow systems.
How close should my 600W HPS be?
The optimum hanging height for a 600W HPS system is only 40cm or 16″. Even at this low height a lot of light will shine on the side walls and have to be reflected down onto the grow. The reflective materials will not reflect all of the light and there will be some light lost (heating the walls).
How far away from the light do you place your 400s?
My 400s sit about 12 inch away (open ended reflectors) but even plants that come a little closer don’t get burnt. There is a couple of fans blowing towards the lights as Cory-and-Trevor described. Like Scraglor says though, don’t forget about the poor beggars around the edge, you do lose quite some footprint as the light is lowered. 😉
How far away should the HPS be from the hood?
Right now its about 2 and a half feet away. The hood/reflector is not cooled or anything. This is my first time using HPS. This is a very simple answer and a very, very common question. Hopefully, the next person will find your thread when they search for the answer:
What temperature do you Keep Your HPS lights at?
Keep temps between 72-80. So the answer is keep the lights as close as possible while keeping their temperature (not room temperature) between 72-80F. Good luck with grow man!!! Oh yeah, one more thing, HPS is for flower, MH is for veg…
