The Wall O’ Water Plant Protector wards off damaging cold temperatures as low as 10°F. Just fill the individual chambers with a garden hose. They’ll protect your young seedlings and plants from the cold of night and extreme heat of the day. It’s a simple principle: During the day, heat is absorbed in the side walls, moderating the temperature inside. At night, heat is released to the inside as temperatures get colder outside- even if the water freezes it releases heat! Thousands of home gardeners nationwide rely on Wall O' water for plant protection.
The red-tinted plastic produces stockier plants by providing that portion of the light wavelength spectrum that plants respond to. The unique open-lipped design allows easier-than-ever filling of the chambers by moving the hose end along the top, instead of opening each individual chamber.
Measures 18" H x 18" diam. Holds 3 gallons of water.
