Hi Zachary,

Do you have pictures of some of your bamboo greenhouses? Also, do you have directions you could share on how to build them? I find that very interesting and II would love to have more details on the herringbone pattern to handle high wind condition.

Thanks, Jerome

Hi,
I also have built a number of greenhouses, and I
dislike PVC because it is made brittle by the sun.
Even fresh PVC has not stood up to the occasional
dtiff gales.  It is also non-renewable.

The other suggestion was metal  - rusts;  High
embodied energy;  does not bounce back from
deformation.

My favorite support is hoop of bamboo.  It is best to
dry the bamboo in a vertical position, helps it
maintain strength equally on all sides.  I protect the
plastic film from roughness with a winding of inner
tube or just electrical tape on the arch.  For severe
winds, i used a herringbone pattern that is elegant
and held up very well, with a winding of inner tube to
tie the intersecting arches.  Plant some for a
renewable structure!

Protecting the plants from the cold is essential, but
much more complicated than a simple hoop house.
Probably an incomplete list of other considerations
that can ruin your plantings:

1.  Irrigation
2.  Pollenization (lack of bees)
3.  Overheating
4.  Inattention!

Regards,
Zachary
