What makes this portable greenhouse is the addition of shelving units.

Most portable greenhouses of this type do not come with shelving which you then have to either buy separately or fashion out of strips of wood on bricks (that works well by the way).

What you see is what you get with this portable greenhouse.

It has a basic tubular frame with full instructions on how to erect (and its not difficult), and is covered with a reinforced plastic cover with a zippered door for access and ventilation.

It can be easily dismantled and put away when not longer in use, and placing your plants and seeds tray on the 12 provided wire-frame shelves will extend the growing season quite a bit.

Your plants will be snug and warm inside this plastic portable greenhouse.

Big enough to walk-in, it is a large and spacious 4.5' x 7' x 6.5'.
