Soil Mixes

The soils stocked at Holland Hydroponics are made up of different substances to achieve certain properties.
Some soils will be fertilised so that minimal additions are needed during the growth stage. Others will contain little nutrition, giving you greater control of what your plants receive.
All of these products are made from porous rock material meaning they have excellent water retention qualities. These products can be used on their own as a hydroponic growth media. They can also be used with soil or coco to give extra water retention and air capacity; simply mix them in with the soil or coco. Usually a 50/50 mix works well, but it depends on your requirements.
