Introduction:
Now a day mostly mass produced vegetables and fruits are GMOs, contaminated with dangerous chemical pesticides and traces of chemical fertilizers. And mostly products labeled as organic, are not 100% organic. So the best and most cost effective option to obtain organic vegetables is to produce them at your home.
So now question arises how can you grow vegetables at home without spending too much? Another problem is you can't have a same environmental conditions around the year and building an environment control growing area is very expensive and it will also required a large space. So my idea is based on these problems/issue that anyone face and how can you solve it without building a something so big and expensive like mars space station.
CBC documentary about organic foods https://www.youtube.com/watch?v=FFRKK54Tj-c and Farmer markets which are consider as original source of organic produce https://www.youtube.com/watch?v=YYwB63YslbA.
Idea and Working principle:
Build a DIY smart, inexpensive and energy efficient organic garden with environment control feature so you can grow any thing 365 days a year without worrying about the suitable growing conditions. This smart garden will either autonomously control the environmental parameters according to a preset values or it can be remotely controlled and monitored through a cloud interface but with minimum power consumption.
