First grow (windowsill)

As was expected, it became too long and started falling, I added support yesterday. Almost no water was added this week because the soil is still wet. Also, I was away the whole week and the temperature inside was around 15-18 (night-day), this could be a reason why there is almost no water evaporating. Honestly, I already doubt that I will have any harvest out of it. Any experience like that?
