How to Build a Micro Greenhouse for Your Instagarden® Raised Bed Garden

(3) Zip tie the arches together at the top by placing a zip tie loosely around the middle arch and then zip tying the lower and upper arches to the zip tie placed around the middle arch.  Pull all zip ties tight.  Rotate the zip ties so that the pointed ends are down.


(4) Cut the greenhouse film to size.  A little bigger is O.K.  Triple hexagon, 13' x 14 '; double hexagon, 12' x 13'; triple square, 12' x 12'; double square, 11' x 11'.


(5)Place the greenhouse film evenly over the arches.  In a hexagon, the longest side runs from one corner to the other corner.


(6) Use the garden clips to hold the greenhouse film to the arches.  Fold the greenhouse film and use the clips to make a tight seal.


(7) Your micro greenhouse will rapidly heat up in the sun and will quickly cook your plants.  Be ready to vent excess heat by lifting up the cover at one or two corners and clipping it to the arches.

This photo shows the same micro greenhouse without its covering.  Attach greenhouse film for snow protection.
