What's in the box?


Fast & Proven ROI! With a 6-12 month average return on investment, PhytoMAX is the best value per watt of any commercial LED grow light. Assuming a harvest every 10 weeks, the Black Dog LED light will pay off the cost difference between it and an old-fashioned HID light in less than 5 months. This is even faster than through increased yield alone! And, when you combine both quality and yield, Black Dog LED lights become much more affordable than traditional HIDs.
The Black Dog PhytoMAX 2 400 LED Grow Lights Implement The Patent Pending Phyto-Genesis Spectrum
The Phyto-Genesis Spectrum in each PhytoMAX-2 light is ideal for both vegetative and flowering growth; only the largest recommended footprint size differs between stages, due to the different daily periods of illumination. You can use the flowering footprint sizes for vegetative growth, although you may need to increase fertilizer and CO2 to make full use of the extra light.
