with that much light, some bushy plants that were tied and trained to allow as much light in as possible could produce a lot of bud..the 600 watt up top with air cooling is a ton of lumens, and having the t5 for (vertical?) on the sides for side lighting should allow all the colas to get good light and develop fully..im not really one with any good experience, but from reading other people's results, i would say fill it up with some bushy plants that you lst or top and you should do just fine.
