What kind of grow light you recommend for 8x4x6 grow tent?
Calculate your grow light requirements first
Calculating your grow lighting requirements really is just two steps - determine your plant’s lighting needs (watts/square foot), and your plant canopy dimensions.
A common mistake new growers make is measuring the dimensions of the grow room itself.
What you really should be measuring is the footprint of your plant canopy.
For example, if you are growing in a 5’ x 5’ space but your plant canopy only takes up 4’ x 4’, you don’t need a grow light capable of lighting the 5’ x 5’ space - it would be overkill.
How to calculate grow light wattage requirements
Most flowering plants grow best with 30-40 watts of light per square foot. Don’t make the mistake of thinking more is better. Too much light can lead to bleaching and burning your plants.
Let's say you are growing in a 8’ x4’ grow space. If your plants need 30-40 watts/square foot, and your canopy takes up 8’ x 4’ of that space,is 32 sqft , you will need 960-1280 watts of grow lighting.So you also need 2PCS 600W LED grow light!
