Do you have the name of the twin wall plastic product for lining the planter? I need this exact item for my two steel planters that killed my roses this summer from the heat.
Thanks Dimitri! This helped me greatly after losing track of the instructions for my big planter! “It’s all downhill from there” I know what you intended to say (easier), but that’s not what this English expression means…it means (worse). 😉
I had smaller ones made which I designed using 1/4 mild steel. They are super sturdy. Mine are bolted together with 1/2 inch bolts. You can design and make them yourself. The tricky part is making sure that if you have two getting them aligned and level with each other.. You can stand on my edges.
