For growbag gardeners these ingenious pots are a must.

They cut neatly into growbags, and allow you to provide easy, accurate watering and liquid feeding (no messy compost erosion or water wastage). The pots’ outer trough
holds 4 pints of water, which seeps steadily into the bag to provide a constant supply of water, while the inner pot holds extra compost and liquid feed, promoting extra root growth, healthier plants and heavier crops. Three pots fit neatly into a standard sized bag, and can be re-used year after year.
