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 LED 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

FAQs
1. What size grow light do I need for a 4X4?
For a 4×4 tent, you will need a LED grow light having a wattage range of 500–600 watts (assuming flowering plants that require a lot of light and are confined in one area. Bougainvillea for medium-light plants require about the same as that).
2. How many plants grow in a 4X4 tent?
A good range of growers selects something between these two extremes, with eight or nine plants in a 4 × 4 grow area. This provides you with approximately 1 square foot per plant. Auto-flower plants are almost always the exact same size, given that they do not have a vegetative phase.
3. Can you have too much light in a grow tent?
If you are growing Cannabis, they like light and an optimally lit greenhouse will provide plants with strong, tall, abundant buds. The led grow light could possibly be hard to control the luminosity, however, and cannabis plants will become too tall as a result.
4. What light is best for Autoflower?
The best LED light for auto-flowering plants is a full-spectrum LED. These led grow lights provide a spectrum of natural light that mimics sunlight and can be used to grow cannabis indoors without any heat or CO2 emissions.
5. Are intake fans necessary grow tent?
Larger grow tents can improve the grow box by using passive intake, but CFM fans will need to be stronger. The intake of the air is just one part of the indoor growing equation. Other factors, such as grow box size, LED grow light variety, and inline fans, facilitate creating the optimum growing environment.
