The 16 inch width refers to diameter of the basket. The chains from top of basket to top pf hook is app. 24 inches and the basket is app. 6 inches deep.
Unless the plant that you are considering has very shallow roots, we would not recommend this planter for tomatoes. Also, the coco liner allows for air to flow through the planter, so it might not keep the soil moist enough to support the growth of the fruit. We recommend a larger bucket style planter and using the Ultomato to support the plant while it grows.
This style is lovely but is likely not large enough. It’s depth is for a small plant only. Also, it rusted immediately, I suggest coating it first with spray paint Rustoleun
the metal is coated with plastic. sorry. do not know what the space is. the diam is 12" so perhaps count the prongs.
You can't make the chain longer unless you are able to purchase another chain and tie the ends of the links together. I wouldn't shorten the chain because, to me, it is the ideal length for the hanging basket.
Yes. Per the instructions, you put your dirt and plant into the hanging basket and then water everything.
