I recently purchased a 195x195x195cm Grow tent that has your company name and Item # 748 on the box. The directions don't make it clear where the five metal rods are supposed to go inside the tent and they are different shapes. Also, there is a white velcro thing in center of ceiling and two in back corner which I don't know the purpose of. Any help and instructions you can give me will be greatly appreciated. The pictures in the directions just aren't clear enough. Thanks
