Semi Hydro Mix


A revolutionary & exciting way of growing plants at home! Soil Ninja's semi-hydro blend supplies porous materials & detoxifying / safeguarding amendments, all to keep your hydro-born props & plants healthy, strong & happy! As with all semi-hydro growing, we recommend regular flushing of the pot to remove built up fertiliser & sediments: ensuring the best free flowing & working behaviour of these very special aggregates.

Semi Hydro Benefits:

  • Extremely fast root growth
  • Very fast water and nutrient uptake
  • Makes extremely fussy plants far easier to maintain
  • Does not require regular watering (due to the reservoir)

Not all plants have the same fertilising routine, that's why when you purchase Soil Ninja's Semi-Hydro mix with fertiliser, it will be included in your delivery in a separate bag so you can fertilise to your specific plants needs.

Head to the product page to learn more about our 8-9 month long lasting feed and how much you should use with your plants. Don’t forget, Soil Ninja's Semi-Hydro mix is compatible with other fertilisers including liquids and organic so you can keep using your favourites.

Semi-Hydro mediums may also be known as: Hydroponics, Pon, Semi Hydroponics
