It would be better to put the fan at the top as an extract fan and have a hole at the bottom for a passive intake. Hammerbutt is right about the aluminium, they use it for heatsinks and high quality pc cases for it's thermal dissipation properties.

You are also going to need a lot more light. 60w equivalent is around 12w actual? (better to quote actual wattages instead of equivalent). I wouldn't want to use less than 125w (actual wattage) per plant.
