We were recently asked, what is the best grow light for a 4×4 tent, so we got to thinking about the different variables involved with the question.
A 4×4 grow tent is not huge, but it is not small. You want to think about a few factors when considering an LED light in a tent that measures 4 feet by 4 feet. First, consider your wattage. For a 4×4 tent you will want an LED equivalent of at least 500 to 1200 watts (depending on how many plants), and second, consider heat dissipation. LED lights typically don’t output heat like an HPS bulb but can still put out enough heat to damage your crop.
Best LED Lights For a 4×4 Grow Tent
In 2019 LED lights have come along way. One major advantage of an LED is they run cooler than a typical grow light. This means that in the confinement of a small space such as a grow tent they won’t overheat your plants. Adding in full-spectrum lighting gives your plants the type of light they need to thrive
