grey pot

The grey planters in these listings are made from polyresin/plastic (linear low-density polyethylene), concrete blended with fiberglass, and glazed ceramic.

Drainage varies by model: some ceramic grey pots include a built-in drainage hole (for example a 1" hole), many polyresin planters are sold without drainage but show a marked spot where you can drill a hole (instructions note using a 1/4" drill bit), and some planters include plugs or openings in double-walled designs that are intended for adding weight rather than serving as drainage.

Many of the grey outdoor planters described are labeled UV-resistant and weather- or frost-resistant. Polyresin models are noted for resisting cracking in cold temperatures, and some listings explicitly state the product is suitable for outdoor use with UV- and frost-resistant construction.

Double-walled grey planters typically include a full-depth inner wall that helps insulate roots and an outer wall with a plug or opening so you can fill the gap with sand or gravel for added weight and wind stability. Listings also note a marked spot where a drainage hole can be drilled through both walls if needed.

These grey planters are marketed for both indoor and outdoor use. Listings mention patios, decks, porches and sunrooms as outdoor placements and note indoor use is fine—if you add a drainage hole, use a saucer or tray underneath to protect indoor surfaces.

Several planters describe adding weight for stability: double-walled designs include a plug or opening so you can fill the outer wall with sand or gravel, and some product notes advise filling the planter base with sand to reduce tipping in windy locations.
