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

Soil.Ninja Fine Semi-Hydro comes in 2mm-5mm.
Soil.Ninja Coarse Semi-Hydro comes in 5mm-10mm.

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)
