Add a 2 x 0.8 metre tier to your grow rack with this set. Each tier raises the height by 40.5cm. It includes the frame for one 2 x 0.8 metre ebb and flow tray and four uprights. The aluminium tube is 25 x 25 x 1.5mm with steel-reinforced corners, rated to 40kg per square metre.
Stacking tiers lets you grow far more without claiming extra floor. The frame supports double as mounting rails for the lights on the tier beneath. That keeps lamps near the canopy of your salad leaves, herbs or seedlings. Build as tall as your grow room allows. Tray not included.
