How much can a 400 watt HPS yield?
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.
How far should a 400 watt HPS light be from plants?
For 400W HPS, the best distance from seedlings is between 12 inches or 30.48 cm (closest) and 19 inches or 48.26 cm (furthest). What is this? 400W HPS grow lights are the most commonly used HPS grow bulbs. These lights can cover around 16 square feet and produce high yields.

How much area does 600W HPS cover?
1.2m x 1.2mEach 600W grow light covers roughly a 1.2m x 1.2m area. That's enough space for 1 - 4 plants.
How many plants can a 400-watt HPS grow?
Generally, grow lights that use 200-400w's can grow around 1-3 plants per light; lights that use 500-700w's can grow around 4-5 plants per light; and lights that use over 800w's of power can grow 6-8 plants per light.
How do you tell if grow light is too close?
The first signs look like thin outlines on the outside of the leaves, so if you catch this quickly you will have a chance to avoid further damage. If some of the leaves start curling up, it might also be a sign that the plant is too close to the light. Good ventilation usually also helps with this issue.

WHAT LED is equivalent to a 400W HPS?
As a side note: A 400-watt HPS luminaire initially supplies about 50,000 lumens. The rule of thumb is to reduce the HPS lumen output by half to determine the LED lumen output, which would be 25,000 lumens in this case.
Does HPS use more electricity than LED?
LEDs are much more efficient than HPS lamps, which allows them to use lesser watts to achieve the same or higher output. The VOLT Grow® 720W FL-1 light produces a higher light output than a standard 1000W HPS light while using 30% less power.
