The Brooklyn Balcony Set
Designed at our North Henry Street studio, this set features three nesting planters that fit perfectly on standard NYC fire escapes or balconies. We've ensured they're heavy enough to withstand high-altitude winds but light enough for one person to move easily.
Why Keystone Sprout recommends this? Because we're tired of seeing cheap plastic pots fly away in October. We've used these for 5 years on our own roof – they're indestructible.
