How far should a 150 watt HPS 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.
What size HPS light do I need?
Using HPS Equivalency and Wattage to Calculate LED Grow Light Requirements
| Grow Tent Size | Total Square Foot | Total Watts Required |
|---|---|---|
| 2 ft x 2 ft | 4 sqft | 200w |
| 4 ft x 4 ft | 16 sqft | 500w |
| 5 ft x 5 ft | 25 sqft | 1250w |
| 8 ft x 8 ft | 64 sqft | 3200w |
How far should a metal halide light be from seedlings?
For seedlings, LED grow lights should generally be mounted between 24-36 inches above the plant canopy – however, this depends on the power (wattage) of the light source.
How far should 250W HPS be from plants?
What is this? For 250W HPS, the distance of the lights from seedlings has to be between 10 inches (25.4 cm) and 14 inches (35.56 cm) from your plants. Place your hand where the seedlings are for about 30 seconds. If the light is too hot for you, that means it’s also too hot for your plants.
How much area does a 400w 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.
How many grow lights do I need for a 10×10 room?
How many plants per LED grow light?
| Grow Room Size | Square Feet | Recommended # of Plants in Veg |
|---|---|---|
| 6′ x 6′ | 36 | Up to 36 |
| 4′ x 8′ | 32 | Up to 32 |
| 8′ x 8′ | 64 | Up to 64 |
| 10′ x 10′ | 100 | Up to 100 |
How far should HPS be from seedlings?
The HPS distance from seedlings should generally be between 10 and 14 inches from plants. However, the optimal distance between an HPS light and seedlings will vary, depending on the HPS wattage, from 10 – 25 inches. For 1000-watt HPS lights, a distance of 5 feet might be needed.
How far should your grow light be from your plant?
12 to 18 inches away
There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.
Can you veg under HPS?
In response to the general question, can you use an HPS bulb for veg, the answer is yes.
How much area does a 400 watt HPS cover?
How far should 400W HPS 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 many watts do I need for a 10×10 room?
Multiply the width by the length for each room or room segment, if applicable. Multiply the result by 1.5 to determine the estimated watts to sufficiently light a room. For example, for a room 10 feet wide by 12 feet long, multiply 10 times 12 to get 120, then multiply by 1.5 to get 180 watts.
How much light do I need for a 4×4 grow room?
You can scale up the wattage with respect to your grow space. Just remember that one square foot of grow tent space needs roughly thirty-two watts of real wattage. According to research, a 4 x 4 requires around 512 watts, but the wattage can range from 500 to 650 watts.
How do you calculate HPS from MH?
What is the Difference Between Metal Halide and High Pressure Sodium? Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange.
