welcome tarmo... i would say read up as much as you can before you start your grow.. figure out what kind of grow that you want to go with.. soil, hydro, dwc, etc.. and what kind of lighting you want to use and try to find a journal that uses the same principals as you and see how they do it , and any problems that they have run into during the grow and you could even ask them for any advice for a new grower or what they would maybe have done differently if they were to do it again.. journals can be a great source of info..
riu has a great community of people who have a lot of knowledge and who are willing to help out in any manner that they can..
have a good time, and happy growing... keep it green....
