1- It's relatively easy and then generally gets harder

2. How do you want to grow? DWC, SWC, E&F, NFT, or Drip? The method dictates the equipment. E&F(ebb and flow) is suppose to be the easiest. That needs a resevoir, pump, nutrients, and pipes/tables for the plants. Electric timers make it a easy.

3. Since you're in Pakistan, you'll probably have to make your own nutes like me. I'll post my new hydro chemical nute recipe that seems to be balanced. I still have to try it though.

4. Anything, some people even grow small trees in hydro.

Take care,
