These are pics of the bluematic that I will harvest next weekend and a pic of my original tent (2X3X5ft) and the newer tent (2X4X7) and lights that I moved her into. Heat and smell will be issues for a grow like you discribe, and with the filter inside the grow space the size of the plants will be small and pot size will be a lot smaller than the 5 gal airpot I used. Yeilds of an ounce from plants 12in-15in should be easy with RQ easy bud and several growers on this site have done more with the same plants in smaller pots. The 135w led and 4 t5s gave off about 7-10 degrees F which was easy to remove with a small fan. Do you have a way to move your exhaust out of the grow room, because if you don't the heat will build quickly, so the room temp should be cool (72-75f). There are wardrobe grow boxes but they can be costly. If the lock on the wardrobe is all the security you are going to have you may want to think about this some more. Do you have a closet to use? Remember you can have too much light.
