When choosing the right plant pot size, you should consider its thickness. Thick containers shield the plant from extreme external conditions, from freezing to blazing. Rapid temperature changes are less harmful since thicker planters are better at insulating.
At Plant Judo, all of our fibreglass planters are manufactured with thick fibreglass sheets to protect plant health, even if premium planter materials like fibreglass are already relatively insulated.
Additional layers of fibreglass are added to boost strength and durability for larger planter sizes, so you never have to worry about your planter destroying your plants.
