The building of indoor greenhouse has started and will be ready within 10-15 days. Its a space of 27feetX8FeetX10Feet. It will be cooled by an Air conditioning unit of 1 tonne. The unit has been procured. We are experiencing unusually high temperatures of 38-40degree celcius in New Delhi and i have my fingers crossed for growing lettuce!
I know people are looking for layout and plans - but we are not civil construction people. We have contracted a company to build us an indoor space - once the space is complete, i will post detailed pics and layout for all to see.
Some of the material has still not reached us and we are waiting for the same. Its great to see the progress of other competitors. We hope to catch up soon. 
All the best!
