Our Seed Starting Methods: Testing New Containers for Better Growth

We’re experimenting with a new approach for starting our seeds, using smaller-spaced containers that are designed to reduce algae growth while promoting healthier plant development. These containers are made from recycled water bottles, and we’ve designed them to hold plants from seed all the way to harvest.

Creating the Test Containers

Our test containers consist of nine separate sections, each one intended to hold a different plant from seed to harvest. To make these containers, we start with an empty water bottle, cut off the top part, and then turn it upside down. The next step is to cut an X-shaped opening in the bottle top, allowing for water drainage once the container is filled. This drainage system also helps the plant roots reach the water, where the nutrient solution is held to support their growth.

To further reduce algae growth, we’ve created an aluminum cover to block light from reaching the water. We’ve also cut holes in the cover to accommodate the individual containers, which will hold the seeds during the germination process.

Setting Up the Growing Medium

Once the containers are ready, we fill them with clay pebbles. These pebbles will support the seeds as they begin to sprout and grow. After the pebbles are in place, we add water to the bottom of the container, making sure the water reaches the pebbles and creates a nutrient-rich environment for the seeds to take root.

Germination Process

When the seeds are ready to be germinated, we’ll place them in the individual sections of the containers. During the early stages of germination, we will need to spray the clay pebbles with water a couple of times a day to help keep them moist. As the seeds begin to germinate, their roots will naturally seek out the water. By spraying the pebbles and allowing the water to drain, the roots will be guided toward the water source. Over time, the roots will grow deeper, extending beyond the top of the water bottle and into the main water reservoir below.

Transplanting to New Containers

As the plants grow and the roots continue to develop, we’ll eventually move each plant into a new container. This will depend on the specific needs and planned use for each plant. Whether it's for transplanting into a larger space or continued growth in a dedicated area, we ensure each plant has the optimal environment for its next stage of development.

We’re excited to see how these new containers will improve plant growth while minimizing algae buildup. Stay tuned for future updates as we continue to share our progress with seed starting! Below, you can also see one of our larger seed-starting setups. In this setup, basil and dandelions are thriving and are almost ready to be transferred to their final containers for continued growth.
