I wouldn't put the power heads on a timer. You can probably do one or two hydor Koralia nano 240's.
The lighting.. those hidden ones aren't that good. What plants are you thinking of growing? You need to decide if you want to grow low light, medium, or high light. You'll also need to determine if you go medium or high, you'll need to get a pressurized co2
fixtures are a great value. Finnex FugeRay for low light plants. Finnex Ray 2 for moderate light. Research those. Or Current Satellite LED
+ fixtures.. You'll need 1 for low light, 2 for medium. The Current lights are neat because you can control the color output plus it has modes for like storm, lightning, moonlights, etc.
