this is the 3rd week after oregano cutting been transplanted into small pots with 4 different mediums and was surprised to find out those in vermiculite/蛭石 grow generally better (light blue pot) than the rest; especially there are 2 out of 5 died in soil base – with 24/7 lights on, water in soil base probably be dried out faster than vermiculite, coconut peat and perlite. 三周后的牛至幼苗在各自培养介质中均有良好的成长趋势；另人意外的是，在蛭石中，牛至的生长高度和强壮度是整体最好的。其次分别是椰糠，珍珠岩，再者是传统的培养土 – 猜测可能是因为在24小时持续的外加光照条件下，培养土中的水分流失比较严重。
