A grow box is a way to grow plants inside your house. They allow you to control the temperature, light and humidity inside your box, so that your plants will get just the right amount of warmth, light and water to help them grow. Inside the box are special growing lights and fans to help your plants get the best environment to thrive. You can also add soil, water and fertilizer to help them grow even better. Setting up a grow box is a great way to have a green and vibrant garden right in your own home.
