What Size LED Grow Light Do I Need?
To work out what size of LED grow light you need, you first need to calculate the exact size of your grow space. The Size Of Your Grow Space When growing cannabis, a good rule of thumb is to use a minimum of 50 watts of light per square foot of grow space. We want to flood our plants with light ( food ) so that they have lots of energy to produce big potent buds. Therefore, we need to calculate the square footage ( length x width ) of our grow space. We’ll then multiply this number by 50w to give us the rough wattage of light we require. EXAMPLE: I have a grow space that is 2ft long and 3ft wide. This gives me a square foot grow space of 6 ( 2ft x 3ft ). I then multiply this number by 50w, which gives me 300w. Therefore, in this example, I would require an LED grow light that was at least 300w. Here’s a table showing the usual wattage for different sizes of a grow space.
