Love hand watering? - Check out our hand water and hand water pro kits
Hand watering is the most common method used to irrigate pots of soil and coco, it's a great method but creates a couple of issues that growers need to overcome. Firstly run off is created by hand watering pots to the recommended 20-30% run off, leaving pots sat in this run off is bad news for your roots and can cause slow growth, both our hand water kits utilise baseline trays to allow run-off to collect in the baseline brain provided which pumps it to a separate waste tank or drain.
Secondly hand watering multiple pots is a pain, our hand water pro kits contain a pump, pipework and telescopic watering lance to make hand watering many pots a breeze! Not only is this a quick and easy method to water many pots it's also much better at hydrating all the coco/soil in a pot as the watering lance sprays out like a shower head - no dry spots in your coco!
Introductory offer! 20% off all soil or coco when you buy any hand water kit instore!!!!
