THANK YOU SO MUCH, SAKSAK10! YOU HAVE MADE MY CHRISTMAS!!!! What I want for Christmas is to kit out my greenhouse with all the best accessories! I found these vent arms at a big store for less than the original website too! If you are so kind as to purchase an automatic arm, you will receive custom 10-15 photos of me in your choice of attire! There are limited number available because my greenhouse only has 2 vents! Thank you so much to all of you amazing fellas who support my green dreams XoXo This item contributes to the Greenhouse Garden Dreams Goal.
