How to make a RDWC system with 5 gallon buckets. Introduction to PA Hydro Stirponics RDWC systems..

Introduction

This tutorial will guide you through the process of building a recirculating deep water culture (RDWC) system using 5-gallon buckets. This method is beginner-friendly and economical, making it an ideal choice for those new to hydroponics. By the end of this guide, you'll have a functional hydroponic system that allows you to grow plants efficiently.

Step 1: Gather Your Materials

Before you start building your RDWC system, ensure you have all the necessary materials:

• 5-gallon buckets (at least 2 for the dual bucket system)
• Net pots (to hold your plants)
• Hydroponic growing medium (like clay pellets or rock wool)
• Air pump (to oxygenate the water)
• Air stones (to diffuse air into the water)
• Reservoir (for water supply)
• Water level indicator (optional but recommended)
• Tubing (for water and air transport)
• Drill with hole saw attachment (to create holes in bucket lids)
• Nutrients (specific for hydroponics)

Step 2: Prepare the Buckets

1. Drill Holes for Net Pots

   • Use the drill to create holes in the lid of each 5-gallon bucket. The holes should be sized to fit your net pots snugly.
   • Space the holes evenly to allow for proper plant growth.

2. Install the Net Pots

   • Insert the net pots into the holes you drilled. Make sure they fit securely.

Step 3: Set Up the Reservoir

1. Choose a Suitable Reservoir

   • Select a reservoir that can hold enough water to supply your buckets. Ensure it is clean and suitable for storing water.

2. Connect Tubing

   • Connect tubing from the reservoir to the buckets, ensuring that water can flow easily into each bucket.

Step 4: Incorporate Air Pump and Air Stones

1. Set Up the Air Pump

   • Place the air pump near the reservoir and connect it to the air stones using tubing.

2. Position Air Stones

   • Place the air stones at the bottom of each bucket. This will help oxygenate the nutrient solution, promoting healthy root growth.

Step 5: Mix Nutrients and Fill the System

1. Prepare Nutrient Solution

   • Follow the instructions on your hydroponic nutrient packaging to mix the solution in the reservoir.

2. Fill the Buckets

   • Pour the nutrient solution into each bucket until the net pots are submerged but not overly saturated.

Step 6: Monitor Water Levels

1. Install Water Level Indicator

   • If you have a water level indicator, install it according to the manufacturer’s instructions. This will help you easily monitor the water levels in your system.

2. Regularly Check Water Levels

   • Make it a habit to check the water levels regularly and top off with more nutrient solution as necessary.

Conclusion

Congratulations! You’ve built your own RDWC hydroponic system using 5-gallon buckets. This system is not only cost-effective but also allows for efficient plant growth in a controlled environment. Remember to monitor your plants regularly, adjust nutrient levels, and ensure proper aeration. Happy gardening!
