This simple product acts like a greenhouse, allowing container or grow bag growers to transplant outside a few weeks earlier than normal. It speeds the growth of heat loving plants like tomatoes and peppers by as much as twenty-five percent, which means happier plants and an earlier crop. The Pop Up Grow Bag Accelerator springs open to form a 112cm (44") tall tube. It is open at the bottom, so it can literally slide over a planted grow bag. The mesh top can be left open or zipped shut to control ventilation and the amount of heat being trapped. Loops at the bottom can be fixed into the ground with metal ground staples to keep it in place. Most grow bags are designed with a diameter of 12" or 14". The Accelerator has a diameter of 24". It will work over containers, too, up to about five gallons. It works well with our Tomato Grow Bags. It is constructed from durable, reinforced polyethylene greenhouse fabric.
It collapses flat for off-season storage, and ships in a box that measures 66 x 66 x 5cm (26 x 26 x 2").
