The product is a movable container that can organise a path or add greenery where digging a permanent bed is impractical. Start with a few useful sizes rather than an enormous catalogue. A landscaper or facility manager should tell you where the units will sit, what plants they intend to use and how excess water should drain. Your sample must show the finish, drainage, safe handling points and the real weight of a completed unit, not only an attractive rendering.
You would cast in reusable moulds, allow the material to cure properly, check the finished dimensions and arrange delivery with a crew able to move heavy pieces safely. Some buyers may need several matching units along a walkway; others need one replacement after a renovation. You could offer standard units and quote separately for a requested finish or delivery beyond your usual area. Before accepting rooftop or raised-deck work, have the buyer obtain a competent professional's approval of structural loading and placement. Your business should not make that decision from a photograph or a phone call.
The practical challenge is that a trough can look simple but cost a lot to move, especially if a small distant order needs special lifting. Water pooling, rough edges or inconsistent colour can also turn an otherwise useful product into a maintenance problem. Speak with local landscape contractors and society managers, test a prototype in the conditions it will face, and calculate a full delivered cost before pricing. If a reliable batch and transport process is possible, this can be a focused supply business; if you cannot control breakage and placement, the apparent mould reuse will not save your margin.
