All i can tell you in a single one random but not so random point, is the "bubbles bubbles bubbles" idea, well it's totally not needed. I used to use ol clogged up year old air stones that emmited but a stream of bubbles in say 3 places, my plants grew big bushy and very buddy none the less. In those lil 15l pots you'll reach the disolved oxygen threshhold without a real issue. Tip Top Science! maybe?
It's only 9:37 and i'm pissed juist a pint of booze in the fridge and a pile of cash on the counter. Sometimes i hate living in a small place where everyone is everyone and just going in and buying a pack of tinnies while pissed will have you held to account the next day. damned rich old people, that would be a simpler way of putting it.
