hey guys first time poster here. i recently got into planted tanks as my reef setup took a dive while on vacation. Too exp to start up again so went back to freshies but wanted to try planted. i currently have a 55g bowfront with some nice plants growing well. id like to try a 10g for my classroom where i work. I have a spare tank and everything i need except lightning. i would like to grow anything lol. probably clipping from my main tank but i would LOVE to get some dwarf hairgrass to cover tank floor. what kind of lighting am i looking for? ive read the wpg threads and thinking cfls are the way to go money wise. i have a clip on grow light from reef sump i might use. but what type of ligt do i need? since its one bulb what range do i want 6500? 5000? 18k? id like to get whiter light but if need be for plants ill go with the yellowish ones. any help would be nice. PS this is old 10g basic rimmed tank u get for 20 bucks lol. thanx in advance!
