How to Build a Self Watering Pot For $10 😱

Summary

In this engaging DIY video, Ken from Epic Gardening demonstrates how to create a cost-effective self-watering planter using PVC, a bucket, and an old t-shirt. The process includes drilling holes for water drainage and installing a wicking mechanism to keep the soil consistently moist. Ken emphasizes the importance of proper design to prevent overwatering and highlights the benefits of using this system for urban gardening. This easy-to-follow project showcases Ken's passion for helping others grow plants creatively in limited spaces. Additionally, he shares that this plan will be featured in his upcoming book on urban gardening.

Takeaways

• 😀 A self-watering planter can be made for under $10 using simple materials.
• 🛠️ The primary materials needed include a PVC pipe, a bucket, an old cotton t-shirt, and potting soil.
• 🔧 Proper drilling is essential: create a one-inch hole in the lid for the PVC and an offset hole for filling water.
• ✂️ Cutting the lid of the bucket carefully helps maintain its structure while allowing water access.
• 🌊 A half-cut PVC pipe serves as a water reservoir, preventing air pockets that can hinder irrigation.
• 💧 Drainage holes are critical to prevent overflow and keep the soil from becoming waterlogged.
• 🧼 Using cotton fabric for wicking action effectively draws water up to the soil, keeping it consistently moist.
• 🌱 The planter's design promotes healthy root growth by supplying water without saturating the soil.
• 🔍 Optional features like a foam line can help monitor water levels and indicate when to refill.
• 📚 The project is part of Ken's upcoming book, which will include various DIY gardening projects for urban spaces.

Q & A

What materials do you need to create a self-watering planter?

You need PVC, one bucket, an old t-shirt, and optional items for modifications.

Why is it important to drill a hole larger than one inch for the PVC?

The hole needs to be slightly larger to ensure a tight fit for the PVC pipe, allowing water to fill the planter effectively.

How does the design of the planter prevent overflow?

The planter includes drainage holes drilled about a centimeter below the lid, which prevents water from exceeding the soil level.

What is the purpose of the cotton t-shirt in the planter?

The cotton t-shirt acts as a wicking mechanism, drawing water from the reservoir to the soil above.

What type of soil mix is recommended for the planter?

A high-quality potting soil mix consisting of one-third peat, one-third compost, and one-third aeration material like pumice or perlite is recommended.

How does the capillary action work in this planter system?

When the soil touches the water pulled up by the wicking action, capillary action allows moisture to move into the drier soil and reach the plant roots.

What is the purpose of the float line in the planter?

The float line serves as a visual indicator of the water level, helping users know when to refill the planter.

How does this planter design support urban gardening?

It allows for efficient water management in limited spaces, making it easier for urban gardeners to maintain healthy plants.

What improvements or modifications can be made to the planter?

Users can add weed fabric, mulch, or different types of plants based on their preferences and gardening needs.

When is the book featuring this planter design expected to be released?

The book, titled 'Field Guide to Urban Gardening,' is expected to be released in spring 2019.
