Description
A Kratky net cup for putting into the top of old empty Gaviscon / Acidex bottles.
Put your acid reflux to work growing plants :-)
Migh be the same as other bottles, the bottle opening should be 25mm internal diameter and 35mm external diameter.
Print upside down, no supports required.
Have not grown anything in it yet, but it probably should grow stuff ok, probably with coconut coir as the tube is necessarily quite narrow to get rockwool or other more solid media down it.
