Increase your output of patio-grown produce by up to 8 times with the compact simplicity of the self-watering Quadgrow and Octogrow systems and enjoy peppers, tomatoes, beans and other crops all summer long. Many plants grown on the patio can perish in the desert-like conditions of mid-summer but these two low maintenance systems keep your vegetables in the rudest of health by way of a 25 litre water reservoir. Simply plant up the 11ltr sized pots (8 with the Octogrow) which encourage big, thick roots to develop, fill the reservoir with water and plant nutrients and let the SmartMats - which provide the constant watering that plants require by way of capillary action - do the rest. The feeder tray separates the soil from standing water to ensure strong, healthy and quick growth. And don't confine your growing activities to the summer months; add optional vented propagating pot lids (available separately) to bring plants on and to protect them from the cold and frost. Holiday watering has never been this simple!
