Is there much manual labour involved with hydroponics?

No. One of the advantages of hydroponic growing is that no heavy digging or weeding is required.  Due to it's adaptability it is possible to set hydroponic systems up at heights which are comfortable to work at, making it an ideal growing method for people who are not able to stand or bend for periods of time. 

The range of hydroponic growing kits, available online from The Achiltibuie Garden, are suitable for positioning at whatever height is most comfortable for the grower. Due to the compact nature of the trough kits, such as the salad & herb kit, it is possible to use them on windowsills.  Gold growing medium is a pleasant and clean medium to use and requires no weeding!
