In winter season, plants are very slow to glow up. Seasonal seeds are very less than other season's one. Plants needs temperature and sunlight to grow up fast. I installed self and LED lights in my house. It needs over 1200 lux but today it accomplished over 3200 lux. In my living room, a sealing light is lack now, but the LED became living light instead of it.

To get 1a, I'm making vegetables in my house also. Especially arugula is easy to make because it needn't sunlight. Some arugula basked full of sunlight, and the leaves are reddish strong, has become bitter and looks like devil. On the other hand, shade-grown they are soft and juicy, making them perfect for salads. This can't be made in outdoor field.
