Today's temperature outside is 12C high but the air inside was 16C as the thermometer shows. It's cloudy through today so the air inside could be warmer if it is sunny.
In winter in Japan the air is usually dry and cold but the inside the tunnels are always moist, which can give a good effect to my vegetable's growth.
I opened a vinyl sheets up for putting some fertilizer on the soil and many spinach sprouts have grown in the past few days.
I found not only the growth of spinaches but that of komatunas.
