Why Buy From Grow Tents Depot
  • High-Quality LED Grow Light: The SF4000 utilizes the latest in high-yielding LED technology with Samsung LM301B diodes, achieving an energy efficiency of 2.7 umol/j. The full spectrum light is ideal for all plant growth stages and comes with a dimming knob for adjusting light intensity. With a power consumption of only 450W, this grow light provides powerful output and uniform canopy penetration for maximum yield. Veg coverage is 5 x 5 ft, Flowering coverage is 4 x 4 ft.
  • New Diodes Arrangement & Dimming Design: The upgraded SF4000 features a diodes arrangement gathered at the edge for more uniform PPFD and a dimming knob for adjusting light intensity. The multi-light connection with unified dimming feature is especially beneficial for large-scale indoor plant growing and commercial planting.
  • Ideal for All Growth Stages: The SF4000 emits a full spectrum of light including white, blue, red and IR (3000K, 5000K, 660nm and IR 760nm). The 3000K diodes provide more reddish light and the 5000K provide more blueish light. The 660nm red and IR light is especially useful during the blooming stage, as it speeds up flowering time and boosts yields. The light also has a natural appearance, making it easy to monitor plant health.
  • Well Made & Solid Construction: The SF4000 is a fan-free, noise-free grow light with a high safety performance driver and fair waterproofing. The updated aluminum material is thick and sturdy, and does not produce a lot of heat. The light also comes with high-quality protective covers for cables and user-friendly packaging. The quality components used in the SF4000 ensure that the light lasts longer and saves you money.
  • Trusted Partner for Every Grower: As a professional manufacturer of LED grow lights for over 10 years, Spider Farmer has always been committed to creating more efficient, suitable, and high-quality home planting equipment for plant growth. The SF4000 comes with an instruction manual, a pair of silver hooks, and a pair of black hangers and is backed by a 5-year warranty at our local repair centers.
