3. Pre-soak from 30 seconds to 30 minutes, depending on size of Rock wool.
4. Water only when there's light - never water in the dark.
5. Optimum room temperature for growing environment is 18.5- 28 for most species. Temperatures above 26.7o C inside the growing media leads to depleted oxygen levels, encouraging root disease.
6. With low light, water with more volume with fewer cycles - and visa versa.
7. Do NOT keep Rock wool sopping wet. lots of algae is a sign of over watering. Minimize watering while plant is young. Too much water prevents root setting which is essential for growing a healthy plant.
