Stealth Hydroponics Multi Spectrum Bubbleponics Kit Bubbleponics is the art of delivering highly oxygenated nutrient solution DIRECTLY to the inner root zone.

Our lights produce the least amount of heat of any grow light system on the market today. This means you can place these lights into any small corner or stealthy closet without heat troubles that most other lighting systems have. The new 315 watt multi-spectrum is no exception to the rule, allowing for cool operation and close plant proximity placement (2-3 inches). The reflector is 100% American made by the folks at SH Hydro in Michigan. Features a quality buffed steel design. Seamed edges and porcelian bulb bases ensure the highest levels of safety. The reflector is also covered by a 12 month Stealth Hydro Warranty.
