grey planter pots

Common materials for grey planter pots include polyresin/linear low-density polyethylene (plastic), glazed ceramic, and magnesium oxide.

Soil capacity varies by size: small grey pots typically hold about 0.88–0.94 gallons, medium–large pots about 3.3–4.3 gallons, and some large polyresin styles can hold up to about 19 gallons.

Double-walled grey planters typically have a full-depth insulated inner wall to protect roots and an outer wall that can be filled (via a plug) with sand or gravel for added weight and wind stability.

Many grey planters are described as weather-resistant. Polyresin/linear low-density polyethylene options commonly note UV and frost resistance and reduced risk of cracking in cold, while glazed ceramic planters are also described as resisting UV and frost damage.

If a planter has a marked spot or plug, add drainage by drilling at that spot. For polyresin double-walled planters, use a 1/4" drill bit and drill through both walls as indicated.

Available dimensions span small pots with top diameters around 8.5–9" and heights about 7–8", medium pots with top diameters near 13.5–14.75" and heights around 12–14", and large planters with top diameters up to about 20.75–24" and heights up to about 16–20".
