The 2026 Spider Farmer G4500 gives serious indoor growers an efficient, reliable lighting solution without the premium price of higher-end commercial fixtures. Its bar-style layout delivers consistent canopy coverage while helping reduce heat buildup and uneven growth. Smart app controls make it easier to automate daily lighting and maintain a repeatable environment from seedling through harvest.
The Spider Farmer G4500 is a 320-watt, full-spectrum LED grow light designed for 2x4 grow tents and wider growing areas up to approximately 3x5 feet. It combines high-density Bridgelux diodes, even bar-style coverage, and WiFi/Bluetooth app control to help home growers achieve stronger growth and dependable yields with less manual adjustment.
The G4500 is built for growers who want strong light output and smart automation without paying for features they may never use. Its high-density Bridgelux diode layout spreads the workload across more LEDs, helping the fixture run efficiently while producing less concentrated heat.
By combining efficient full-spectrum lighting, app-based scheduling, and broad canopy coverage, the G4500 can replace less-efficient lighting systems while reducing the time spent manually adjusting timers and dimmers. It offers a strong balance of purchase price, energy efficiency, coverage, and long-term reliability.

Bring efficient, automated lighting into your grow space with a fixture designed to deliver consistent coverage throughout the entire cycle. The Spider Farmer G4500 offers the output, control, and long-term value needed to build a productive 2x4 indoor garden without overspending on your lighting system.
The G4500 is ideally suited for a 2x4 grow tent. Its wider light spread can also cover growing areas up to approximately 3x5 feet, depending on hanging height, plant stage, and desired intensity.
Yes. With a 913 μmol/s PPF and 2.85 μmol/J efficiency, the G4500 provides the intensity needed for both vegetative growth and flowering in an appropriately sized space.
A separate timer is not required when the light is operated through the Spider Farmer app. The app allows you to create automatic on/off schedules and control brightness throughout the day.
The app can gradually increase the light from 0% to your selected brightness at the start of the cycle and gradually dim it before shutoff. This creates a smoother transition than instantly switching the fixture on or off.
The G4500 supports both WiFi and Bluetooth connectivity. Basic operation and dimming may still be available through the fixture controls, while scheduling and advanced smart functions are managed through the app.
Search for Spider Farmer in the Apple App Store or Google Play Store and download the official Spider Farmer app.
Spider Farmer recommends pairing the G4500 with a 4-inch ventilation system for a typical 2x4 grow tent. The exact fan requirement may vary based on room temperature, humidity, duct length, and additional equipment.
Yes. The open spacing between the LED bars allows air to circulate through the fixture while spreading heat across a larger surface area. This can make the grow environment easier to manage than fixtures with a more concentrated design.
Yes. The G4500 can be paired with a compatible Spider Farmer GGS Controller for expanded environmental integration and control.
Most in-stock orders are dispatched within approximately 1–3 business days. Preorder products and inventory delays may require additional processing time.
Eligible returns are accepted within 30 days of receipt, subject to the Garden GrowShop return policy and required product-condition standards.
The Spider Farmer G4500 is backed by Spider Farmer’s official 5-year manufacturer warranty. Warranty coverage applies to eligible manufacturing defects and is subject to Spider Farmer’s current warranty requirements, exclusions, and claim procedures.
