An Economical Carbon Dioxide Generator
Keywords: Cultivation: Aldrovanda vesiculosa,
In his article, Dr. Adamec mentions that Adrovanda
vesiculosa appreciates the infusion of carbon dioxide in its water.
You can create your own carbon dioxide generator of only a few cents per
week. I have been using this method for some time with certainly noticable
improvements in the growth rate of Aldrovanda vesiculosa.
Five litre or 1 gallon container with sealed lid.
250 grams or 9 ounces sugar
1 teaspoon yeast
A length of hose to reach from the generator to the Aldrovanda
Prepare the container by drilling or cutting a hole into
the lid. Make the hole large enough so the hose fits snugly into it. Insert
the hose into the hole and carefully seal it in place to prevent gas leaks
(any sealant, such as silicone, will do). When the container is ready,
fill it with three litres of water, then add the sugar and yeast. Seal
the lid with the hose attached and submerge the other end of the hose
in the Adrovanda tank.
Depending on the temperature, the reaction may take up
to eight hours to begin. The generator will produce carbon dioxide for
up to two weeks. At that point, clean out the generator, add a new mix
of water, sugar, and yeast, and it will resume its production of carbon
