Good Luck dude,If i was to start again then i would go with growing a good few plants,Has many has i could get in my room ,But just flower them small ,So your aim is to get around a oz of each plant,Its in my Opinion the Fastest way of getting nice weight from the start,But then once you get to grips with the way the plant grows and How the room is working ,Move over to less plants but bigger and aim on hitting bigger weights,Strain Choice is Important in your first grow too ,I would do something like Pineapple Express,Because i love the plant,The bottoms on that strain are even solid,Or Exodus Cheese From Greenhouse another easy but great plant.Producing great med's for your self is a great feeling ,Knowing what you are taking in ,You have grown the plant ,so you know whats gone into it,Get a Blue Lab ppm/ec/ pen .More Important than a Ph Pen in my Growing,
