We've made them before, but it's a lot of work, considering what the
cost. If your interested I can send you the plans for the one we made.

Good luck,

Chuck

Robbin,

For many years we have run a practical with our students to construct gypsum blocks.
The document referenced below is extracted from our lab handbook.

The things work but need to be individually calibrated as the water release characteristics of the blocks is not constant.

Dear Friends,
I'm doing a project on auto irrigation. Can anyone
please tell me if gypsum blocks, for measurement of
soil moisture ,can be made by me at home? If so how
can i make them?
 An answer to my query will surely help me a lot to
continue with my project.
Thank you.
Robbin Joseph
