SproutBoxx Pro 4 Indoor Grow Kit (3x3FT, 480W, 205CFM)
The SproutBoxx Pro-4 Complete Indoor Grow Kit is our custom 3x3 kit, equipped to produce some of the largest and highest quality yields possible in 9 sq ft of space.
- a high performance SproutBoxx LM301H YB-4K 480W full spectrum grow light with onboard dimming and spectra control,
- an energy efficient 4 ” fan with programmable temperature and humidity controls and 1050+ activated carbon filter kit,
- a durable 100% light-proof and >99% reflective 3x3ft grow tent, with an all-metal clip joint frame and reflective splash tray.
The SproutBoxx YB-4K 480W grow light combines Samsung LM301H horticultural LEDs and Sanan UV, Far Red and IR LEDs for our optimized full spectrum, with oodles of the blue 437 nm wavelength that stimulates growth, bioactive content and phytonutrients, an industry-leading PPE of 3.1 µmol/J, and an excellent, uniformly high PPFD/PAR that supports high maximum yields of 2.8 g/W (dried). The programmable Inventronics LED driver is 96% efficient and default power settings can be over-written to new, user-defined values.
The SproutBoxx 40W programmable fan has a digital thermostat controller and plug-in humidity and temperature sensor that allows optimization of the tent’s micro-climate and fan speed to user-defined temperature and humidity values. This efficient, versatile 4 “ fan can be programmed to come on for a specific length of time at a set speed, to trigger when temperature or humidity conditions are met, or to run manually at a chosen speed, shifting up to 205 CFM of air. It’s solid but lightweight, and rated at <28 dB-A, quieter than many comparable 40W fans.
The SproutBoxx 3x3 ft grow tent has a tough, light-proof and waterproof 600D polyester outer with a PET silver Mylar® lining inner (and splash tray) that reflects >99% light, providing the highest level of light penetration and diffusion. With mesh-screens over ventilation windows and dual-sleeved duct and cable ports, it keeps fluff and insects out while providing plenty of fresh air and a sealable environment.
With the SproutBoxx Pro-4 indoor grow kit, you have the ultimate high-yield setup for a 3x3 and can grow like a pro with unbeatable features, incredible specifications - and at outstanding value.
