G-Tools Height Extension Set for Grow Rack 2 x 0.63

This height extension set is the single most efficient way to increase your G-Tools 2 x 0.63 grow rack's productive capacity. If your grow room has headroom to spare, this kit lets you add tier after tier without buying a second rack or rearranging your entire space.

The extension set is designed exclusively for the G-Tools 2 x 0.63 modular grow rack. It consists of a correctly dimensioned frame for the 2 x 0.63 ebb and flow tray plus four uprights. Every component is pre-matched to the base unit, so installation is straightforward - no cutting, drilling, or improvising brackets.

Each tier adds 405 mm to the overall rack height. In a room with a 2.4 m ceiling, for example, you can comfortably accommodate a three-tier configuration. Growing area effectively doubles or trebles on the same floor footprint. That matters in smaller facilities where floor space is the primary constraint.

The frame rails are not just structural. They also serve as the mounting points for your lighting on the tier beneath. This keeps cabling tidy and lamp positioning consistent. Pair each tier with a Sanlight EVO or Q-series LED panel for efficient, full-spectrum coverage across the tray. G-Tools publish PPFD data for each compatible lamp type, so you can verify light intensity targets before purchasing.

This extension set suits growers running ebb and flow or flood-and-drain schedules who want to scale production without increasing their room's physical footprint. It is equally relevant to propagation setups, where a lower-intensity tier can be dedicated to clones while upper tiers run full-power veg or flower lighting.

Grower’s Note: When stacking multiple tiers, think carefully about airflow. Each additional level restricts vertical air movement, so position a clip fan or ducted intake to ensure fresh air reaches lower canopies. Ensure your nutrient pump and reservoir capacity are also scaled up accordingly - a three-tier ebb and flow system can flood two to three times the tray volume of a single-tier setup.
