Prof. Charles Hartman, Ph.D.The pressure bottle method is the easiest homemade watering system for gardeners. It is simple to use, requiring few, if any, materials and no technical skills. It definitely waters plants for periods of up to three weeks during vacations. Ideal for beginners seeking reliable do-it-yourself systems.
Bottle Preparation
- Use 2-liter plastic bottles for best results
- Drill two 3mm holes precisely 1 inch above bottom
- Clean bottles thoroughly to prevent contamination
Setup Mechanics
- Fill bottles completely with room-temperature water
- Place bottles directly in plant trays or saucers
- Position holes facing downward toward soil
Vacuum Seal Creation
- Water flows only when tray level drops below holes
- Air pressure difference creates automatic shut-off
- Prevents flooding through self-regulating action
Testing is crucial to system reliability before vacations. Measure flow rates by timing water output. It should take less than two minutes for one cup. Adjust the hole sizes if the flow is too fast or too slow. Conduct a 48-hour test run to assess the system's ability to function properly.
This technique is particularly suitable for small to medium plants such as herbs and annuals. Place the bottles approximately 6 inches from the base of the plant. If the pots are larger, use several bottles. Dark colored bottles significantly reduce algae growth in sunny locations.
Care consists of a monthly vinegar flush to prevent mineral buildup. The bottles should be replaced every six months, as plastic deteriorates over time. This inexpensive system outperforms costly products. Go on vacation without stress, knowing that your plants are properly watered.
