Watching

As my training at masters’ field was finished, in these days, I have been in my green house. However it is quite small. It has 2a (200 square meters) space. And I stay there for 4, 5 hours. What my doing there is watching. Watching the plants from the standing position or sitting position again and again. And I see something new.
Today I see one new thing.
It is not good to leave the ping pong ball size organic fertilizer which is made from rice bran, because warms live in there. And the material rice bran should be used until it is fresh to avoid warms to live in it.
