I purchased this from a flea market app and used it for about 5 months in a greenhouse. I stored it without use last year and the year before, but I'm selling it to organize my belongings. The exterior is relatively clean, but there is some dirt around the fan due to use. Pic Corporation is no longer in the greenhouse business, and this product has been discontinued. Power-on confirmation has been done. I don't know the performance when it was new, but it's in the same condition as when I purchased it from the flea market app. Please consider this item with the understanding that it is a used product. If you are concerned about the details or are looking for a new item, please refrain from purchasing. The original box and instruction manual are not included. Only the items in the images are included. Product Information: From the manufacturer The internal fan recreates a gentle breeze (like a zephyr) that is not harmful to plant growth, and it circulates the air inside the greenhouse, activating the plant's physiological functions. It also helps to equalize the temperature inside the greenhouse, saving on heating costs.
