Wait you're 12?
No complaints as I'm still only 15
But I'm a bit worried if you're mature enough to be playing with test kits and such early on like this.. I mean you do not want to drop a vial of test results for ammonia or the like. I admittly wasn't mature enough at first and lets say nothing but disaster when I first started (at 14).
Besides, at my age I already have 2 little jobs to support everything I own, my parents won't spare a dollar (can't afford it) and that's working out just fine.
