So ive been doing a lot of research lately and i got most of what i need to know down i think, if not i can reference to something, but im trying to debate what i want to do. Im using a old half bath in my house, and its 28x36x72 (inches). I got a 75watt fluorescent light right now but i plan on upgrading it in the near future, a 30gph pump (pretty weak but it was free), and a air pump. As far as my questions, i can't decide what type of setup to use. Its between a ebb'n'flow or a bubbler system. What do you guys think would be the best type of system since my growing area is so limited, and has anyone ever grown in a bathroom? Do the tiles on the wall / caulking effect the plants at all? But like i said, first time growing, giving it a shot, dont expect anything awesome but you gotta start somewhere. Oh, and i heard fluorescent lights are better for vegetation but when you want to start flowering is when to switch to the HPS lights, its what i heard.
