some advice need with a diy bubbler set up

G,day all from downunder,

I am in the stages of setting a small Bubbler (I think thats what its called) up, I have a Ten Litre Bucket as the res with Lid and have cut two holes to snuggly fit two plastic pots (Couldnt find any Baskets),Any way my questions are this.

1. With the pots they are the same as you would use for dirt with holes only in the bottom, should I cut more in the sides or will the bottom ones be enough?
2. For a medium Is straight vermiculite ok to use or does it have to be blended.
3.Is ant one familiar with the Brand of Nutes called "Grow Rite and Bud Rite and are they any good ie Ph level stability and is thier quality ok.

Any advice would be great.

aslong as the pots look like a net pot or a strawberry basket type...you should be fine. drilling holes around the whole thing would be better....

as far as a medium I would go with rockwool and hydroton...I havn't experimented with anything else yet...I like to go with what works.

Not familiar with those nutes...who makes them?
