Spider Farmer is widely considered to be one of the most trusted names in the LED grow light industry. The company was founded in 2009 and has since expanded its reach around the globe. Its headquarters are located in Alhambra, California, and it has warehouses located around the globe. Spider Farmer is an official Samsung partner, allowing them to supply their top-of-the-line diodes to customers who want to purchase one of their products.

In this review, we will compare the SF4000 and SF7000, two of Spider Farmer's most popular models, to determine which is ideal. In addition, we will cover the characteristics that make them so desirable to growers around the globe, as well as their production and quality performance.

If you're looking for an inexpensive, professional-grade grow light, the Spider Farmer SF4000 450W LED Grow Light With Dimmer Knob is a great option. It's perfect for indoor plant growth, and it offers a wide variety of colors to choose from—including white, red, infrared, and blue. The individual bulbs can also be adjusted by a light switch for added control over the growth of your plants. 

Meanwhile, The Spider Farmer SF-7000 is a powerful 650 watt LED grow light that offers a lot of value. It uses Seoul Semiconductor diodes instead of Samsung diodes, and provides the full spectrum your plants need to grow: 2800K - 3000K, 4800K - 5000K. It includes infrared and ultraviolet LEDs as well, so you can rest assured that your plants will be getting everything they need to thrive.

When it comes to coverage area, SF-7000 offers a 5x5 foot coverage area. It’s clearly larger than SF-4000's 4x4 foot coverage area. So if you are up to commercial scale, the SF-7000 is going to be your best pick. 

But when it comes to the price, there's no doubt that SF-4000 is a better deal. It offers the same amount of coverage area, but at almost half the price. So, if you’re new to indoor gardening and don’t have much experience with growing plants, we recommend that you go with SF-4000. It will give you an idea of how LED grow lights work and how much yield they produce. Once you get comfortable with the results, then it's time to upgrade to SF-7000.

Overall, both lights are great value for money and they will give you excellent results. Made from the highest quality materials and with a high attention to detail, both of these lights are built to last.
