4.2.7 Length of clusters to top

The length from the uppermost flowering cluster to the top of the plant amounted on average 16-18 cm with no significant differences between light treatments (Fig. 15).

4.2.8 Distance between clusters

The distance between clusters increased from about 20 cm to about 24-26 cm during the growth period. On average amounted the distance 21-22 cm and was independent of the light treatment (Fig. 16). Interestingly, the light treatment under young plant production did not had an influence on the distance between clusters of first clusters.

4.2.9 Length of clusters

The length of clusters decreased from about 35 to about 20-25 at the end of the experiment (Fig. 17). The cluster length of the first cluster was not influenced by the light treatment in young plant production. But, plants that were grown in continuous production under “Hybrid+LED” had a significant higher cluster length when grown under HPS lights in young plant production compared to LEDs in young plant
