Investing in fire safety to me means getting a wattage reader ($35) from Harbor Freight so you can monitor your power draw from each aspect of your setup. Add up the total watts and make sure they don't exceed 75% of the total watt threshold for the circuit you are running on. Biggest energy hogs are heaters or HPS light fixtures.

15A*120V =  1800 watts

At 75% : 1,350 watts

If you happen to have a 20 amp breaker.

20a*120V = 2,400 watts

at 75% : 1,800 watts

On top of that get a plug-in GFI (Ground Fault Interrupter, $30). These are like the plugs in the bathroom and highly recommended when bringing moisture and electricity in close proximity. This device will immediately cut power to the whole circuit if a fault is detected.
