air pump for hydro?

golf ball is smaller in diamater but higher in surface area. its also cheaper, winner winner.

ALso just use the cheap golf ball type airstones, there are diffuseers but they are expensive, you have to hard wire them to your tote, which makes cleaning thm a pain

Cleaning? What do u have to clean, is there regular maintenance needed for anything like air stones, pump or clay pebbles?

[potentcheesydick]

Also any specific tubing size needed? And is it any golf ball airstone?

clean the golf ball as it will get black in time.
I just use fishtank line, think its 5 or 6mm.
Go for a decent sized ball.

The air lines from the manifold to airstones is 4mm.

and yes, you need to clean hydroton, lines and airstones after every grow. you should soak your hydroton in 5.6 ph water before it goes near a net pot, for at least 48 hrs, using ph down along the way to keep the ph at 5.6ish.
otherwise your ph will rocket when you start the system up and the water covers the bottom of the net pot hydroton
ANd get the 2 inch golf ball airstones and black airline 4mm, as it wont give algae a chance to grow inside it, like the clear stuff does.

ok
