For a rectangular growing area, a linear lamp moving system is preferable. The self propelled Light Rail 3.5 Intelli Drive is without question, the finest linear lamp-mover available. It uses no pulleys, chains or gears. Simply mount the standard 6 foot track over the desired area and place the lamp-moving drive-motor onto the track. The Light Rail 3.5 Intelli Drive is supplied with adjustable switch stops, so lamp travel can be any length you wish. This is perfect for a start-up size garden through to a full growth garden. The standard 6 foot track may also be extended. These complete kits are available in either 6 RPM or 9 RPM models.
