4.2 Development of tomatoes

4.2.1 Plant diseases and pests

Neither plant diseases nor pests were observed.

4.2.2 Height

Tomato plants were growing about 2-4 cm per day and reached at the end of the experiment more than 4 m (Fig. 10). Plants were significantly taller when grown under HPS lights.

Letters indicate significant differences at the end of the experiment (HSD, p ≤ 0,05).

4.2.3 Weekly growth

The weekly growth amounted 15-30 cm. Plants under HPS lights grow on average significantly more compared to the two Hybrid treatments (Fig. 11).

4.2.4 Number of leaves

Plants had on average 15-17 leaves. However, “Hybrid high” had on average a significantly lower amount of leaves compared to the other light treatments (Fig. 12).
