it can be done for sure. i am putting a unit together right now in the same size of space. i am picking up my equipment this weekend and it is going to cost me just shy of $950. the only problem i could see is the fact that you will be in toronto. i live in BC and having such a small grow op out here is no problem. i will be able to harvest around a pound per crop, which would be way more than enough for you. toronto, however, being a much larger city might give you more problems. you will have to make sure there is no smell and if you are going to be living in an apartment, make sure you don't have a meddling superintendent who will be sticking his nose into your business. other than that, welcome to canada my friend!
