That should do it for ya for the expensive stuff.
You also need a simple fishtank thermometer for your res, and at least 1 thermometer with a %RH reading (about $6 at wal mart) for the plant area.

Not a stupid question, friend. %RH stands for percent relative humidity. Our friend MJ has a range that the %RH should be in during veg and another during flower.
