IMHO sog is the only way to go you cant go wrong with perpetual smoke..I think you will be fine, using the veg nutes until you buy flower nutes i personally use the same nutes from seed to weed, its a walmart special mix lol, but it works like you wouldnt beleive...ok you have one area to work with right now, I am going perpetual 12/12 but I think you should flip to flower right now, when your girls show, flip back to veg take clones let them root, this should give you enough time to pull some funds together to create your second area, my recomendation would be to make a veg clone area it will require less light thus cheaper and faster to put together, after that is done you are set to go perpetual..........granted this will increase the time before you smoke your own, but as long as you manage and maintain it you can become self sufficient
