The OM Solar Greenhouse | OM Lumber-Drying method | Eco-Materials

Results of the OM Solar Greenhouse Experiment
The OM Solar greenhouse was originally designed with a conventional sloped roof. Extensive experimentation, however, led the OM Solar Association to develop its present design. Here below are the results of one comparative growing experiment.
(With the OM Solar greenhouse, crop yields and their particular characteristics will naturally vary according to climate/weather conditions, cultivation methods, and other factors.
Experiment venue: Hamamatsu, Shizuoka Prefecture, southern orientation
Sowing period: Late December, 2002
Objective: To compare yields on the basis of cultivation in four different types of greenhouse. |

| A |
An OM Solar greenhouse, with underground water-sprinkling system/
with heat-collecting panels/with underground heat transmission |
| B |
An OM Solar greenhouse, with no underground water-sprinkling system/
with heat-collecting panels/with underground heat transmission |
| C |
An OM Solar greenhouse, with no underground water-sprinkling system/
with no heat-collecting panels/with underground heat transmission |
| D |
A conventional greenhouse, with no underground water-sprinkling system/
with no heat-collecting panels/with no underground heat transmission |
| Data collected on: Outdoor temperatures, indoor temperatures, collected hot air temperatures, soil temperatures, humidity levels, volume and weight of vegetable yields. |
|
Respective weight of individual greenhouse yields:
Greenhouse A grew the largest leaf vegetables. Greenhouse B grew the largest root vegetables.
