A good quality LEDs grow light is a must investment for a 4×4 tent. You have made a great effort to grow plants indoor with an efficient control system through a grow tent.

The 4×4 grow tent is a great size as it’s not too big or small. The lights that can be used in a tent this size vary dramatically. You can use almost any fixture from traditional single-ended fixtures, LED lighting, or Ceramic Metal Halide. The only fixtures that might be avoided are double ended fixtures but that has more to do with height restrictions.

Since LED lights are usually preferred for grow tents, we will only discuss best LED grow lights in the market for your tent. For a 4×4 tent, you should have a grow light having an actual wattage range of 500-600 watts (assuming flowering plants which require a lot of light and are congregated in a single area. Vegetative growth for high-light plants need about half this wattage). Many growers are also using a combination of 4 LED grow lights of 300w or 2 lights of 600w for their 4×4 tent.

So here I'd like to introduce some best LED grow lights for 4*4ft grow tent under $600

Grow Tip:

You need to be careful regarding the height at which you hang the light above the plants. As it can cause a burn or stunted growth in plants. It is recommended to keep the light at a distance of 30-32 inches in the start. Then you can closely monitor the plants over the time to avoid any burn and allow for a proper stretch (depending on your area size). If there is the stretch between the nodes or too much space between the sucker leaves, you can decrease the height of LED light and further adjust it unless an optimal height is achieved to maintain healthy plants’ growth.
