What Garden Grids do I use for a 4x10 garden bed?
If your garden bed is 4x10, your best option should be to use 2-4x5 Garden Grids (found here), which you can connect together with our multi-Garden Grid connection manifold (found here). Overall, this layout would measure ~44"x~9'3" and you would be able to control each Garden Grid independently of the other via the manifold. We size all Garden Grids to fit the interior dimensions of most garden beds. We have a video on the manifold page showing this if needed. If you have any extra planting area outside of the perimeter of the Garden Grids, you can simply twist the tubes around so they spray outward and water that extra garden space. Here's a quick video about this.
Note: Always check the interior dimensions of your garden bed before ordering, just to make sure this is a good fit. Garden beds are most often solid in nominal dimensions, meaning the listed dimension is usually not exact, but a close representation of the actual dimensions. For instance, your 4x10 garden bed may have a planting area of 45"x9'6". This is because garden bed materials are sold in nominal dimensions (for example a 2x4 board isn't 2"x4", it's actually 1.5"x3.5"). Garden beds are also made of varying thicknesses making their interior planting areas smaller the thicker they are.
