First I tried just 4 seeds in flowerpot, and all of them started fine. So I decided to go little bigger with my experiment. Nearly 1 square meter. That schooled give me close to 1Kg of rice (0,83Kg to be exact).
As it is my firs year and just a testing run. Anything more that those 30 seeds that I planted will be gain.
I will post more pictures as plants will grow.
