white widow is a very popular strain on this site... go to advanced search and limit the search for titles only and threads with more than 20 or so responses. then you could just try to model your grow after someone who had great success. Also, if you want 3-4 plants you might want to consider feminized seeds or figuring for 50% males plus some seeds might not germ. If you are starting with seeds you could be looking at up to ten to end up with four. If you live close to a hydroponics store i would go in there, even if it is just to look around and get ideas. At the one by me the guys running it are extremely helpful and get excited to help new growers, in addition i would have saved hundreds if i went to a hydro store first...along with finding this forum before i started...there is a ton of great info on this site and a lot of ways to save money, time, and suffering (both for you and the plants). Good luck with your grow
