How to Water Medium and Large Plants in Raft

When it comes to hydroponic gardening, the raft system is one of the simplest and easiest ways to grow plants. The system consists of a floating raft that holds plants in net cups, which are suspended in nutrient-rich water. While the system is user-friendly, one of the biggest challenges that hydroponic gardeners face is watering medium and large plants in the raft system. In this article, we will provide you with a guide on how to water medium and large plants in raft and keep them healthy.

1. Use Good Quality Water

One of the essential things that you need to consider when watering plants in the raft system is the quality of the water. Plants absorb everything that is present in the water, so it is vital to use good quality water to ensure that your plants grow healthy and free from any water-borne diseases. You can use tap water that has been filtered using a reverse osmosis system or buy purified water from a store. Avoid using chlorinated or fluoridated water as they can harm your plants.

2. Adjust Water pH and PPM Levels

The pH level and the PPM (parts per million) level of the water also play a crucial role in the health of your plants. These levels should be adjusted, depending on the type of plants you are growing. The ideal pH range is between 6.0 and 6.5, while the recommended PPM level is between 300 and 500. To determine the pH and PPM levels of the water, you can use a pH and PPM testing kit. Once you know the levels, you can adjust them accordingly by adding pH-up or pH-down solution or adding nutrients to the water.

3. Check Water Levels Regularly

Checking the water levels in the raft system should be done regularly to avoid under or overwatering the plants. As the plants grow, they absorb more water, which means the water levels will also decrease. Make sure that the water levels are above the roots of the plants by checking them daily. If the water levels drop, add more water to maintain the proper level.

4. Use a Timer

Using a timer is one of the easiest ways to ensure that your plants are watered regularly. A timer will help you avoid forgetting to water your plants or overwatering them. It will also help you maintain a consistent watering schedule. Set the timer based on the needs of your plants and the environmental conditions in your area.

5. Use a Water Pump

If you have a large number of plants in the raft system, manually adding water to each plant can be challenging and time-consuming. Using a water pump can make your life easier by distributing water evenly to all the plants. Water pumps come in different sizes, so be sure to get one that is appropriate for the size of your garden.

Conclusion

Watering medium and large plants in the raft system may seem daunting, but with these simple tips, you can ensure that your plants thrive. Always use good quality water, adjust water pH and PPM levels, check the water levels regularly, use a timer, and use a water pump. With these practices, you can enjoy a bountiful harvest and enjoy the benefits of hydroponic gardening.
