- rapid growth. Following the studies made was found that trunk diameter reaches 40 cm in 7 years, much faster than other varieties. Rapid growth will reduce harvest time and increase wood production;
- high quality wood, straight, tall and dense trunk;

2. Heat. For germination is best stable +22- +24C temperature. It must not change at night or during the day. If possible, use heated propagators.
3. Moisture. The seeds cannot dry out. They must be kept moist and in good contact with the ground at all times.
SOWING. Use only clean seed sowing substrate. It can be purchased at any major supermarket.
Moisten it. Sow on the ground, press them by hand or with a sprayer. Germination requires light, so do not cover the seeds.
