Adding organic fertilizer can add nutrients to the soil, and can likewise help balance pH levels, as most organic fertilizers have a pH of around 7.0. The addition of grit or perlite will give an extra layer of better structure and drainage while still giving proper aeration and drainage.
Normal room temperatures 60-75°F/16-24°C. To set blossom buds, the plant needs 8-10 weeks of cool 60-65°F/16-18°C days and 45-55°F/7-13°C evenings in winter.
