This is a Portulaca/Purslane seeding that I am going to reproduce from stem cuttings.
The base (#1), buried in the sand to keep it from tipping over, is made of 2 black containers sewn together.
On top of the base is a white container (#2) which collects excess water. It can be lifted out and the water emptied.
On top of the white container is a black container (#3) with holes punched in the bottom for drainage.
The seedling is planted in #3 in cocoa noir/potting soil/etc., partial covered with clay pellets.
A pole secures the "Tulip" (#4) which has drainage holes in the bottom. The Tulip is made from an upside-down milk carton with holes punched in the lid, one large hole for the stake to go through and smaller holes for drainage.
