Hello friend brimax, to understand the cold boxes and their usefulness I saw your video, by the way very well edited, and I was surprised to see so interesting work, which serves as greenhouses, where they can plant and then in winter time eat the fresh herbs as if they were seasonal, here we do not have snow, only rains in winter, however it was a great investment in greenhouses echos mesh and tubes, nationally, and it is painful to see today all demolished, seeing its excellent Work gives me much more strength to continue in the struggle against these people of the town, if they used this kind of ideas, we would save a lot of time and money, because when the harvests are not seasonal their price becomes unattainable for the people. Really my respect for you, for your work of bricomania, making your farm a very exciting place to live and enjoy, there is no healthier and richer life, than the one you live, I congratulate you both for being a couple worthy of follow their example, as honest and hardworking people who love natural life. my special greetings for the princess of the house Candy, my regards and regards friend @brimax
