Small spaces doesn't mean you can't have a garden. Apart from the tub garden I did earlier this month, here is a slightly larger container garden in brick planters. Each is 20 land impact.
This square planter is 2.9x2.9.
The round container is 3.4x3.4.
The rectangular container is 3.8x2.5.
This kidney-shaped planter is 4.3x2.2.
They are copy, mod and no transfer and partial mesh.
These container gardens are available for 59L each at my in-world store and the Marketplace. Please see the demo at my in-world store.
