This is Atul from Pune. I was hydroponic enthusiast just like you two years back and now I am a commercial Hydroponic grower. Take a look at my Strawberry project YouTube - straw berrry in poly house 7/12
I also assist people in growing fruits and vegetables at home. Biggest problem comes when you need to find proper nutrients. After discussing with International experts I have purchased a formulations for various crops taking in consideration our weather and other variables. I sell those for house hold users online on e-bay. eBay Seller: atulkalaskar: Home, Decor Furnishings items on eBay India
