Preparing pots with compost.... an experiment

This is a bit unconventional, but since I'm still experimenting , I guess it's okay. So I had bought these cement pots ages ago and had a lovely underwater ecosystem flourishing, complete with fish, underwater plants and snails... but despite the thermostat, nothing survived the winter.
So, I decided to use them for my gardening.

What I did was, I used the shells from when I had the fish to line the base....hoping it will act like gravel.

Then , I put in a layer of all the dead leaves and cuttings and vegetable scraps from the kitchen, that we would normally use for compost. I also tend to put in used tea bags before I put the soil, especially for tomatoes, chillies and other Nitrogen loving plants.

Lastly, I put in soil. Planted the seeds, watered it just a bit and that was that!
