Getting your growstones ready for gardening is easy.
- pH pen from Bluelab
- General Hydroponics pH Up and pH Down solutions
Always soak and rinse your growstones before using them. Soak them in pH balanced water and adjust as necessary until they have a neutral pH. Growstones make an idea medium due to their rough surface which forces roots to branch and grow thicker which promotes water and nutrient uptake in the plants.
