What we know€¦ Stationary indoor grow lighting only shines light on the specific areas of leaves that are directly beneath it, which can cause limited growth and even damage to the plant similar to sunburn. LightRail Light Mover solves this problem by moving grow light kits over the tops of plants, so that the leaves of the plants get light at different angles. This activates photosynthesis on parts of the plants that would not normally receive much light with a stationary grow light system. Stationary grow lights cannot diversify themselves in order to allow your plant to absorb it at the optimum levels and light energy can be lost. LightRail helps distribute the proper level and concentration of indoor grow light on the leaves for 40% of the photoperiod. This allows the plant to reach optimum Leaf Area Index, the most important factor in increasing yield. Also, by moving your indoor grow light, you can now safely get your indoor growing equipment and gorw light systems closer to your plants for a more efficient use of the wattage available. LightRail is the single best way to maximize your indoor grower equipment and indoor grow setup. Solidly made in the USA since 1986, LightRail 4.0 AdjustaDrive is the DIY light mover of choice throughout the wordwide indoor gardening community with an instrument grade drive motor that runs on only 9 watts, digital control circuitry, heavy duty ball bearing carrier wheels and a self-clutch drive design with automatic traction control. Manufactured by Gualala Robotics, LightRail has important electrical certifications (C CSA US or CE) and flammability ratings (UL 5 VB) and is RoHS compliant. LightRail has a two year manufacturer warranty, runs at a safe 28-42 degrees C with a flame retardant electrical enclosure, as it should be, while imitator grow light movers run as hot as 107 C (170 F) and their electrical enclosures are likely made of flammable plastic. Without quality, there is no value and if it does not say Gualala Robotics, it is not a LightRail. LightRail AdjustaDrive, the DIY light mover scalable for any space, should be considered an important part of your indoor grow kits, and an integral part of any indoor grow lights. Grow equipment, especially indoor plant light, should always be maximized and LightRail is the most effective way to get the most out of your lamp kit as part of your indoor grow light system.
