Effect of air-pot containers size on vegetative growth of Cannabis sativa L.

Abstract

The difference in growing container size affected plant growth, which is the same as for cannabis, which lacks data about the size of the growing container. Thus, this study was to investigate the different sizes of air pot growing containers on the vegetative growth of Cannabis sativa. L. (Hang Kra Rog Phu Phan variety). The completely randomized design was used and divided into 5 treatments with sizes of square growing containers (Air pots) (15x20, 20x20, 30x30, 40x40 and 50x50 cm) and 4 replications each of 4 cannabis. The growing media contained a ratio of loam soil, coconut coir and compost of 2:1:1. The data were collected weekly for 2 months. The results showed that the suitable size of the growing container was 30x30, 40x40 and 50x50 cm, which had the highest height, while the container sizes of 30x30 and 40x40 cm showed the most significant number of leaves. Moreover, the container with dimensions of 40x40 cm exhibited the greatest width and length of the leaves. Additionally, both the 40x40 cm and 50x50 cm containers showed the highest measurements for trunk circumference, canopy width and root length. Consequently, the 50x50 cm air pot emerged as the optimal size for cultivating cannabis.
