Talk:Saladin box

To fix

Still open questions:

• when was this design popular? How often was it used? when did it get in disuse?
• are box germination designs with perforated floors still considered Saladin boxes or not?
• are boxes with electrically driven screws still Saladin boxes?
• are round vessels with rotating arms of screws still Saladin boxes?
