What Size Light Do I Need for a 2x4 Grow Tent

The traditional recommendation for LED grow lights was around 32 watts per square foot for flowering plants. So, for a 2x4 tent, you'd want a light of at least 256 watts. However, newer LEDs are more efficient, so you might need less wattage if you're using a high-quality modern LED light. For example, a good quality 150-200 watt LED light might suffice for a 2x4 tent if it's a full-spectrum, efficient light, such as the one we are going to introduce in the following.
