Once they do get some size they'll go (still into their net pots) into one of the large 15 gal buckets. Originally I wanted to cut a hole in the middle-ish for the net pots but the acrylic we bought was 1/4 inch thick (we wanted sturdy and it actually took Mr Hound and a standard circular saw to cut so we improvised. But it IS sturdy.

There are two ten inch airstones in each bucket (which I may trade out for bubble wands....I'm still on the fence about them but Opie and MVP both suggested them) if I'm not happy with the way they work. And a little side slot on each tub to check ph, add nutes or whatever without having to lift the plant out of the bucket.

The pump has six airlines which is enough to power both tubs and their accessories.
