Repurposed (Recycled) Pop Bottle Propagators
Repurposed (recycled) 2 liter bottles make great propagators simply by adding a deli container on top (16 oz - on the left, 24 oz on the right). They're a perfect fit.
Note: I no longer use perforated caps on the neck. I now install a polyester (batting material) soil retainer/capillary wick starter..
