There are a good range of online and high street retailers that can provide hydroponics supplies in the UK.
Ones that I have used include:
- LS Systems: Extensive range of specialist pipes and drippers. Main focus is commercial horticulture but it’s worth a look at their online catalogue to find out what’s available.
- Growell: Good online presence and a number of outlets in London and the West Midlands where you can purchase hydroponics supplies. Helpful counter staff and a good range of stock .
- BHGS: An Evesham based stockist of various chemicals used to make up nutrient solution.
I have also had good experience with some niche suppliers of specific equipment:
- Scalesworld: bought a 6kg by 1gramme scale to allow me to weight chemicals accurately.
- Northern Polytunnels: supplied my 8.2m x 12.8m (27 x 42 feet) polytunnel.
