Thank you for dropping by SnSstealth and leaving this little advise, I was planning on doing exactly that, good to have a confirmation that my idea is a good one !
The only problem I have is that I can't have vegging and flowering plants in the same room for now because I have no way to make the closet in my grow room light proof and I can't really leave them somewhere else in the house. So I figure out I'll need to throw a little more cash in and buy a grow tent. This will give me the possibility to have a section for flower and another for vegging and I'll have a light proof environment for my flowering baby and later on for drying.
