Add a 110 x 63cm tier to your grow rack with this extension set. Each tier lifts the rack 40.5cm higher. You get the frame for one 110 x 63cm ebb and flow tray and four uprights. The aluminium tube is 25 x 25 x 1.5mm with steel-reinforced corners, holding 70kg per square metre.
Stack as many tiers as your grow room allows and widen your growing area without spreading out. The frame rails act as mounting points for lights on the tier underneath, keeping lamps near the crop. Good for stepping up a microgreen or salad operation. Tray not included.
