First grow (windowsill)

This week was quite good, it became stronger and grew more leaves. I added about 2 cm of soil to slightly reduce stem length (and because my pot allows that). Also, you can see a yellow sensor in the pot, it's a b-Parasite ZigBee-based DIY plant monitor, which reports temperature, moisture and humidity. I want to use it to help with watering, let's see if it helps.
