Well I have read through your post and I think its a great thing that you're doing, so I'd be happy to help you in any way that I possibly can. So for starters... if seeds are good for growing indoors, they're great for growing outdoors. You can always grow outdoors. Also, yes it is very possible to grow in containers throughout the season. If you mean you want to grow in one container the entire time and never transplant... well then you may have some issues. However, transplanting is very simple, and healthy for your plants. You could start it in something small as a seedling then into a 1 gallon or so container for a while. Then once it fills that thing up, plant it into a 5 gallon container or something similar in size. Perhaps even larger, depends on the size of your plants and so on, just something you kinda need to feel out for yourself. But the 5 gallon should easily carry you through harvest. I've harvested plants outdoors in 3 gallon containers that have produced 6+ ounces easily each.

Good luck! And please continue to post any questions you might have, and I will respond in a timely fashion for you. I'm sure plenty of others here would be happy to contribute advice to your cause as well. My biggest piece of advice would be... just don't try to do too much. Do whatever your common sense guides you towards doing, and pay attention to you plants responses, making adjustments accordingly, and you'll be happy with the results. Too often people think that cannabis plants are unique and need ridiculous amounts of care/work, but they're very resilient and grow well on their own until people begin stressing them out too much by fixing things that aren't broken. Oh.. and have fun in the process!
