There's nothing quite like enjoying veg you've grown yourself, and Grow Bags are a convenient way to grow spuds and greens where space is at a premium - perfect for use on patios and balconies, but the small footprint means these can be used practically anywhere. Each grow bag in this set is made from non-woven fabric and has a capacity of roughly 7 gallons (26 litres). The bags measure 35cm tall by 30cm in diameter.
