Damn! Gonna be a lotta work getting all that new gear set up! Sounds like the mini jungle just got a sweet upgrade. I've been dealing with fungus gnats myself, and being a fully organic grow, I generally deal with them by putting out yellow sticky traps, watering in some beneficial nematodes and top dressing with neem meal (only during veg, neem can cause a weird flavor if used during flower). These things combined tend to keep the problem at a minimum, and since the gnats are more of a nuisance than anything, I don't let them worry me unless they get bad. Good luck with the grow.
