How do you calculate grow room lighting?
Let’s say you are growing in a 5′ x 5′ grow space. If your plants need 20-30 watts/square foot, and your canopy takes up 4′ x 4′ of that space, you will need 320-480 watts of grow lighting.
How far should my LED grow light be from my plant?
12 to 18 inches
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.
How much area does a 1000 watt LED grow light cover?
about 7 feet square
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 many grow lights do you need for 4 plants?
Recommended assuming 4.0 sq ft/plant
# of Plants | Square Feet | Wattage from Wall |
---|---|---|
1 | 4 | 120 to 140 watts |
2 | 8 | 240 to 300 watts |
4 | 16 | 500 to 650 watts |
6 | 24 | 700 to 860 watts |
How many lights should I use in my grow room?
Standard advice says you should aim for 32-50 watts per square foot of grow space. More like 25 watts if your grow space is a dedicated veg tent. So if you were working with a 3′ x 3′ space, you’d theoretically want an LED light with a power draw somewhere between 225 watts (vegetative) and 450 watts (flowering).
How high should light be above seedlings?
Where Should Grow Lights Be Located? 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 close should a grow light be to plants?
In general, you’ll want to hang your light no more than 12″ away from your plants. – Remember: after 12″ fluorescent lighting loses its power, so make sure you don’t raise it any more than 12″ above your canopy otherwise your plants aren’t getting light energy.
How many grow lights can I run?
If you are unsure what voltage you are running at, please see our helpful grow light electrical circuit guide….Lights Per Circuit Calculator.

What area will a 600W grow light cover?
1.2m x 1.2m
Each 600W grow light covers roughly a 1.2m x 1.2m area. That’s enough space for 1 – 4 plants.
How do I calculate the coverage area of a grow light?
In order to calculate the coverage area of a grow light you already own, you can simply look up the manufacturer provided grow light coverage chart. You can also purchase a PAR meter or LUX meter and measure the light intensity across your grow space. Then compare it with what your plants actually need.
How do I use the calculator to calculate lighting placement?
Just select the layout, enter the room’s dimensions, and hit calculate. You can also use the calculator to determine the placement for recessed task lighting above a surface by using its dimensions rather than the entire room. Note: You can actually use any format with the calculator – inches, centimetres, or feet.
What is the grow light calculator and how does it work?
The Grow Light Calculator is part of the Coco for Cannabis Grow Light Guide. We encourage you to read our Grow Light Metrics Primer to learn what all the data means. We explain how the calculator works and the science behind our formulas in our article, “ Calculating Grow Light Efficiency, Coverage & Harvest Potential ”.
How many grow lights do you need for your grow room?
Grow lights have gotten more and more powerful as technology continues to advance, but at a certain point, 2 lights can cover an area more effectively than 1. There are also grow rooms that will need even more lights. For example, an 8’ x 8’ grow room would likely need 4 grow lights, and a 10’ x 20’ room could need up to 8 lights.
