I have always want to grow Bonsai inside the room, but I have never succeeded. Most bonsais need strong sunlight. After a few months indoors, they just died.
This time round I put an LED lamp above it. LED is energy efficient. In addition, I placed the lamp very close to the plant to maximise light intensity. I leave the light on six hours a day.
Let’s see three months after today whether or not the bonsai is still alive happily.
