Made from pure clay mined in Germany, Seramis is a high quality growing medium suitable for use in drip re-circulating hydroponic systems and passive hydroculture. It’s main features include:-

  • Inert, ph neutral and naturally disease resistant
  • When used in hydroponics systems cannot be overwatered
  • Does not break down, can be cleaned and re-used many times
  • Very strong capilary action
  • Increased nutrient uptake, plants respond to changes in nutrient formulation immediately

Seramis produce a nutrient suitable for use with houseplants, for all other plants we recommend General Hydroponics Floraseries range. General guidlines for growing in hydroponics are:-

Establish plant in propagation substrate of your choice, then place plant in a suitable amount of Seramis growing medium – as a rough guideline we tend to recommend around 10-15 litres per plant, the longer the life of the plant the more medium you should use. Seramis performs best in constantly fed drip re-circulating systems, in this type of system it’s impossible to overwater so the pump can and should be run constantly. In the early stages however, you may wish to hold back on watering slightly for plants that have been established in Rockwool or a similar type of growing substrate, until the plant has put down a good root system into the Seramis itself.

At first glace Seramis looks expensive, but it’s simply a case of getting what you pay for. It’s already a huge seller in Germany and Holland – it’s now started to get very good traction in the UK market with several leading retailers stocking it.

Supplied in 30l bags.

Seramis FAQ’s:

 Can I reuse Seramis?

Yes you can, once you have finished with your plant separate the old roots from the Seramis, give it a good wash through with tap water and it’s good to go again. You could also an enzynme product like Cannazym to give the new plant the best start in life possible.

How does Seramis compare to Clay Pebbles?

Overall it’s slightly better as a sole growing medium, we would say. There seems to be better nutrient uptake, better root formation due to increased surface area, plants seem to be less prone to pythium and overall plants just seem to be happier in Seramis, in our experience and that of our customers.
