Low cost Hydroponic Project

I am planning to construct low cost hydroponics project. Creating this thread for the community members to share idea, brainstorm for the benefit of everyone.

I understand shaded net can be created with Bamboos and may be with polythene sheets.
Can we also create Pipes  using Bamboo instead of plastics?

Typically what will be the investment required per acre for Planting Tomato or Capsicum using Hydroponics?
Can you recommend any source for buying Materials, Bio fertilizer, plastic pipes etc?
I understand the motor pumps will breakdown often. What  brand model we should buy? Any source?
