Turn Any Milk Crate Into a High-Performance Planter.

Got a milk crate? Now you have a planter. The Smart Pot Milk Crate Liner is a breathable fabric insert designed to fit snugly inside standard milk crates, instantly transforming them into air-pruning grow containers. It’s the perfect solution for urban gardeners, balcony growers, and anyone who wants to maximize their growing space with materials they already have.

The breathable fabric walls promote the same air-pruning root health that Smart Pot is famous for — denser roots, better nutrient uptake, and healthier plants — all inside a repurposed crate.
