HI all. After much surfing of the web trying to find a good discussion forum this one appealed the most. I'm about to embark on the perilous journey that is cannabis growing

and need some advice desperately. I've already spent a few hours sifting through threads for a general idea on how to begin but there are just so many different theories I'm becoming confused

! I was hoping maybe if I start my own thread and give you all a basic outline of what I'm trying to achieve a few of you may find a little time to help me out along the way. Once I've begun I'm hoping to post regular updates on here so you can watch my babies grow along with me. I have listed below the points I feel most neccessary:-
1. The basic idea I have at the moment is that I am going to use a special closet grow room built from scratch by myself! I hope to grow 2 - 4 plants in there so I need to know how big to make the grow room to accomodate this number of plants. The beauty of making the grow room myslef is that it can be designed to the exact requirements of what you need to achieve!
2. What are the best seeds to use for a first time grow?I've been told to try AK-47, Big Bud and lowrider 2. This is vital to my success. I need seeds that are relatively easy to grow for my first time.
3. What lights to use and how to position them within the grow room? Again ive heard different things regarding good lighting strategy.
4. Ventilation and climate control. I need to know an easy and cheap way of maintaining the temperature and humidity within the grow room.
5. What nutrients to use if any? The best potting soil and how often to water the plants.
6. Finally it would be helpful to know how long each stage of the plants life lasts? Germination to flowering. And what is a good way to induce flowering?
I'm hoping to buy feminized seeds to eliminate having to worry about males. I want to grow the plants in soil because i think a hydroponic setup is a little advanced for me at this stage! I have a budget of around £400 or $800.
Any help you can give me would be greatly appreciated. Please tell me anything however small because im a complete novice! If you dont think my budget is big enough let me know and I'll see what I can do.
Thanks for reading!
