yes.. the roots stay lots cooler..with the insulation value being about twice what a refrigerator has... I can water them wth cool water n the mornng.. and hours later t's still a bt cool.. even sitting on the 165* roof that many of them are...not to mention the great weight savings over the treated wood I'd make the containers of before..
Real cute Debbie who comes to sit at the table... faries or trolls.. [ others ? ] I need a bit more whimzey for my cactus/succlent foam planter
