Hi
@PlantMania
The black plastic would be under the Pea Gravel and is used to prevent grass and weeds from growing inside. It also serves to help prevent the gravel from being pushed into the ground. I will be using the material that is used for a liner for water / fish ponds. It is thick and should out last me.
I looked at a HF greenhouse and the construction is not what I want. I am being very kind and trying not say anything offensive.
The Palram is strong, well braced and has better overall quality.
Thank you Stewart,
