Hey everyone. I've been researching like crazy about lighting because soon I'll be setting up my 55g for the first time. (Excited ) I've found a ton of threads about what the flat out, absolute best fixtures are (which were all completely non-conclusive... haha) but I'm not Bill Gates here. I can spend around $100 to $150 on a fixture. I'm interested in the Odyssea 48" 4x54w t5ho (which by the way.. I don't understand how wattage changes how my lights will affect my plants) but I'm wondering if there are better options for the amount I can spend. And as a secondary question while I'm on the topic, how does wattage affect the setup? Some people are running way less that 54w bulbs.. But they seem to work fine? Thanks guys.
