mix consists of- roughly - medium bark ( 33% ), fine seedling bark (33% ), sphagnum (33% ) and sprinkling of oyster shell pieces into the mix. I don't tightly pack this mix into the pots/bottles either.
Photo shows base of bottle and holes - I cut those using a knife - across each "leg" of the Sprite bottle. There are 4-5 holes in total around the sides of the bottle too.
This was done about a month ago - if you look carefully you can see a root already, there are lots of others.
