I planted small plants of strawberries.
You can plant small plants flowers, spices, or vegetables like lettuce. Lettuce is best to do just two holes per bottle.
You can plant from seeds.
Fill the pot up a little above the level of lying bottles and wait until it reaches the level.
After that the maximum can never exceed the level of lying bottles and the minimum should be at the level of sand aquifers
