How long shuld i veg?

Unfortunately there are too many variables to give you an accurate answer to your question. There are a huge list of things to consider when deciding that. How big your grow space is and how much light power you have are the major determining factors in how long you should veg. You also have to consider things such as the size of the final pot you are going to use. It looks like you have a heavy indica so it will most likely grow smaller than a sativa dominant. On average 5 to 7 weeks is what you want to shoot for unless you want to grow a huge plant or it is a slow growing plant. The best advice I can give you is to just continue to document your grow on the diary and stay in touch with the community here. A lot of great people here that are glad to help you along the way and advise as the grow progresses. Sorry I couldnt really answer your question but hope this helps. The more information you share on your updates the better advice you can get. Good luck. I will follow along.
