Each pack contain loos rock wool/stone wool 25 litre if you’re growing water hungry plants in containers then hydro-wool is a idea. Hydro-wool can support house plants while watering just once every 2 to 4 weeks. When growing in clay pellets mix in hydro-wool to make water and nutrient distribution more uniform and have a moisture buffer in case the pump fails. Hydro-wool also fine root growth which leads to larger more vigorous growth. Tip: if you are using a drain-to-waste system, then you do not need to ph condition the hydro-wool. Just fully saturate the wool with a ph 5. 5 nutrient solution. Usage: on its own as a potting mix. Mix with any potting mix to improve aeration and water holding capacity. Mix water gro-wool into your sandy garden soil to improve water holding capacity.
