Note: Liners are "squashy" so they can be pushed through the opening to expand and fit closer to the pot wall once inside. Liners can also be cut down to size with scissors for a neater fit if they bulge inwards slightly at the top. This is an important step. Without drainage holes in the plastic, you’re creating a swamp and not many plants can survive those conditions!

Some gardeners suggest using weed membrane as this lets the water through and prevents soil touching the wood. In my experience, it doesn’t provide as much protection as plastic. Don’t go right to the top edge of the box as that looks unattractive. You only need plastic as high as the soil line. That was 4 years ago and it’s still going strong. Environmentalists report plastic can take up to 450 years to break down, so your wooden liner will go the distance. Still, we offer guidance as to the shape that you want to ensure that it is up to the recommended standards.Hydroculture plants - These require a hydro kit for assembly, this includes a waterproof pot liner with a base wide enough to accommodate the hydroculture grow pot. The size tip provided for each hydroculture plant provides a recommended size for the external diameter of the decorative pots that will accommodate the specified waterproof liner. But remember! The planter must have drainage holes or roots will rot in the consistently wet soil.

Lower carbon footprint which helps reduce the amount of poisonous gas emission thus protecting the Ozone layer Any kind of metal in wood will cause damage and allow wet to enter – but in my experience glue doesn’t hold the liner in place. Staples cause the least wood damage – but don’t go overboard! For plants in soil the key size in determining the maturity and fullness of a plant is the diameter of the grow pot. The larger the diameter, the more mature the plant. How do we size hydroculture plants?Liners come in various sizes to fit the internal dimensions of the pot and can be trimmed down to size to create an unobtrusive barrier for the plant and soil to be potted into, whilst protecting the pot from unsightly calcium or fertiliser deposits from the soil.
