This grow rack stacks two ebb and flow trays of 110 x 100cm on two tiers. It measures 136cm tall and 115 x 102cm on the floor. The aluminium tube frame is 25 x 25 x 1.5mm with steel-reinforced corners, holding 70kg per square metre. More tiers can be added when you want extra growing area.
There is space for a 62-litre tank beneath the lowest tier. The pump floods both trays with nutrient water, then it drains back as the pump switches off. That cycle suits leafy greens, herbs and propagation trays. Wheels are an option on request, and the trays are sold separately.
