Weeks 1 and 2

The first two weeks there was steady growth.  The plant was in a small 0.2-liter pot under  18-hour light.  He kept temperatures at 22°C during the day and 18°C at night with 75% humidity.  By week 2, the seedling doubled in height to 4 cm, So he needed to move to a larger 50-liter pot.

Weeks 5 and 6

The plant was getting larger at week 5 and showed signs of vigorous development.Because the day temperature increased during this week the nutrient schema was adjusted.Mosquito started with applying Low-Stress Training (LST) and by week 6, the plant shot up to 40 cm. Such fast growing is a clear sign of the nearing flowering phase.

Weeks 7 and 8

By week 7, the plant height was 55 cm which was great, but it also was showing signs of overfeeding. The feeding was adjusted because of this. Week 8, the plant reached a height 70 cm. The nutrient mix was improved and the plant kept getting bigger, so it was neccasary to cut some leaves and to keep the growtent suitable.
