it should work ok you don't have to have your exhaust fan in dresser if you need the room just the carbon filter and vent tube to fan on the outside should have small fan blowing on the plants though
homemade compost will have just about every thing in it that you need bat shit is just about all nitrogen and not to much of all the other stuff plants need
depends on what you want I like ffof put it in it, water good to get all soil wet no dry spots must have good draining pots put under good light live it alone untill soil is dry down about 1inch from top water again fill the different weight between dry and wet soil will help you later on good luck

make sure if your going to go with hydro to keep water temp in check our you are in for a rude awaking that's why people say your better off with soil you have a buffer which ever way you decide with check to make sure you have enough power in that room you don't want to over load circuit and...
I have not used air pots, but this is the first year I have used fabric pots, and I like them a lot no root bound was told to use one size smaller then what you generally use due to the end of the roots keep dieing off when getting to the air
it does not matter where you put your fan really, but just in case you need a carbon filter you want your fan after that they work better sucking air then blowing air good luck
if you have two tent maybe if not to much light on clones otherwise there going to be huge or just keep chopping the tops off while training them a good strain in good soil from seed will be huge in that time
