has your brain fuse popped yet from the mass of info on lighting? my first run through it all had my brain going in swirls.
I have pretty much the same light fixture that Jetajockey linked and it is plenty of light for my plants. i have it on a 40g tall so same foot print as your 30 but taller. you would be able to grow medium-high light plants with that IMHO
. If it is too much light you might be able to just use one bulb. depends on the ballast and wiring.
Just tell hubby that his creation was great to get you by for the little while and you love him for going through all that trouble for you but your plants need some more light and you didnt want to annoy him with more on the honey-do list.
If he cant accept that then distract him with a nice warm peach cobbler when ordering the new light fixture. LOL
lights are getting cheaper but it's hard to figure out sometimes what the light fixture is capable of since the cheaper fixtures don't have all the necessary info posted.
Let me know if you dont want to have an empty 180g tank sitting around. i can take care of that for ya
