There are a few members here that are doing good with the grow box .

I prefer my intake on opposite side as exhaust simply because it draws fresh air through the plants and not straight out but would do the trick

The aluminium foil needs to be turned around to the
dull side if I remember reading here some where. You will need to lower the lights or move plant closer.
