It’s fantastic! The Wall O’ Water Plant Protector will ward 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 will release heat!) This product is used successfully by thousands of home gardeners nationwide 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 in. H x 18 in. diam. Holds 3 gallons of water.
