Watering plants regularly remains a problem

While growing plants can be a very enjoyable and relaxing hobby, one of the main problems faced by most gardeners, especially those who live alone is that the plant has to be watered regularly. For some plants, if the watering is delayed by even a few hours in the morning, the plant will start wilting. So travelling for a short period of time can be a major problem for a person who is living alone as most of the plants will wilt and dry up, if they are not watered daily.

However in India due to the limited demand, these plant watering kits are not easily available, hydroculture seems to be the only alternative
