RE: Pumpkin Lighting/CO2

Water
Sugar
Baking Soda
Distillers yeast

Individual recipes will vary, as will the amount of CO2 produced. If you are
making alcohol, obviously you need to add fruit, grain, etc.  I think Karl
made this specifically for the pumpkin plants and added fertilizer to his
mix.  (Not sure of the purpose there.)  When he went to the store to get the
yeast, the guy exclaimed "...and you just throw this stuff away?".  This is
why I think I will try to make some wine while I am experimenting with the
pumpkins...probably pumpkin wine.  He placed the stuff in a bucket with an
air trap (well known to you alcohol producers), and then placed the bucket
at the lowest point in his greenhouse.  He used a fan to circulate the air
and CO2 during the nighttime hours, as he read that the ambient CO2 levels
increase during the day. 

Hope this helps

I would like to hear more about the CO2 experiment , how does it work ,
how do you go about getting more CO2 to your plants ect.  If anyone has
information please let me know

Thank you

Sue

considering the CO2 experiment this next growing season. If you remember
Karl Dietz, he used it very successfully this year. His experimental
plants were almost double the size of his control plants. He only used
the system to get the plants started though. I think he produced in the
700+ range, but I'm not sure which plants. He used two different systems
with little difference between them. I know the cheaper one did not have
much control on how much CO2 was produced. The cool thing about CO2 is
that you can make it by fermenting stuff. So all you beer and wine makers
out there set up your next batch in your patch. Your pumpkins will
appreciate it. -Gus -----Original Message----- From: GPR-hip@t-online.de

To: pumpkins@hort.net Subject: Re: Pumpkin Lighting Hi, I would say the
limiting factor is the CO2 content in the air rather than sunlight. The
normal CO2 content in the air is about 0.03 percent. But the highest
photosynthesis rate of a plant occurs at a CO2 concentration of about
0.05 to 0.06 percent. However, concentrations of more than 0.08 to 0.1
percent are harmful to the plant. I know back in spring someone on this
list talked about using additional CO2 in the root zone of the plant.
What happened to that experiment? Any results? Growing the plants in a
greenhouse with an additional CO2 supply would be something to try. Just
my two cents... Best wishes, Martin What's left? Sunlight...the one
