still easier to rip hood off
half the plants in the LFS are not designed to grow... just last more than a week in a goldfish bowl
google DIY CO2 systems and see what you can make out of a 3ltr juice bottle some yeast and airtubing....
also think about a decent substrate ( or tablets if you can't be bothered ripping it all apart)
lights: red and blue spectrum makes plants grow well.... makes plants look crap though, need a good mix (IME 1 x sunlight to 2x tropical does well)
