Eliminate a huge list of dangerous chemicals from your tap water to ensure safe grow conditions for exquisite plants. Tap water usually contains high concentrations of contaminants especially in hard water areas such as London. Over a period of time, the concentrations can accumulate in the grow medium and endanger your plants. For a truly clean and nutrient solution for your plants, we would recommend using an Reverse Osmosis (RO) filter. When filtered add 20% of tap water back to your RO water to create a 80/20 mix by doing this you will provide a buffer to regulate pH fluctuations.


The filtering systems we provide at London Grow remove, chlorine, unneeded salts, heavy metals and organic contaminants. With filtered water, you'll increase uptake of relevant nutrients and improve the development of beneficial bacteria in the substrate.
The water filters available at London Grow are easy to use and to connect. Simply connect up an outlet and inlet pipe. The units are eco-friendly and feature enhanced absorption capacities. You'll preserve the microbial activity in the grow medium for better and bigger crop yields. Eliminate chlorine in your nutrient solution and remove unwanted sediments in no time!
