Step-by-Step Instructions:

1. Plan Your Design:

• Decide on the size of your tower based on the space available in your greenhouse.
• Determine what plants you want to grow (e.g., herbs, leafy greens, or fruiting plants) to choose the appropriate setup.

2. Gather Supplies:

• See the comprehensive list below for items needed.

3. Build the Tower Structure:

1. Base Preparation:
   • Use a sturdy container (like a 5-gallon bucket) as the base for the water reservoir.
   • Drill a hole near the bottom for the submersible pump’s tubing to pass through.
2. Vertical Tubing:
   • Use a PVC pipe or similar material for the vertical column.
   • Cut evenly spaced holes (2-3 inches in diameter) where plants will sit, staggering the positions for optimal light and space.
3. Plant Holders:
   • Fit net pots into the holes. Secure them to ensure stability.

4. Set Up the Water Circulation System:

1. Install the submersible pump in the reservoir and connect tubing that will carry nutrient solution up the tower.
2. Create a drip system at the top to distribute water down the column. Drill small holes in the tubing to allow controlled water flow.

5. Add Growing Medium and Plants:

• Place a growing medium (e.g., clay pebbles, coco coir) in each net pot.
• Insert seedlings into the growing medium.

6. Mix and Add Nutrient Solution:

1. Mix hydroponic nutrients in the water reservoir following the product instructions.
2. Test and adjust the pH to ensure it stays between 5.5 and 6.5.

7. Assemble and Test:

• Attach the vertical tube to the base and secure it for stability.
• Turn on the pump to ensure the water flows smoothly through the system.

8. Maintain Your Tower:

• Monitor water and nutrient levels weekly.
• Check the pH regularly and adjust as needed.
• Clean the system periodically to prevent algae or clogging.
