Dear  Alex, Crispin, Hugh, Paul W., Dale, Christa, Tom and others,

I found  the document Alex cited about CO2 in greenhouses to be  
extremely  interesting.

http://www.omafra.gov.on.ca/english/crops/facts/00-077.htm

There  has been occasional discussion at BEF Stove Camps and elsewhere  
on  the use of larger TLUDs in small greehouses for both heat and for   
CO2.  With some proper CO and CO2 or O2 and smoke detectors to  provide  
safety features, the igniting of quality-checked large TLUDs  WITH FAN  
ASSISTANCE (to assure best combustion and to help with  circulation)  
would make great sense for small greehouses.

The  document gives some basic numbers that we could use for   
calculations, but all the examples are for very large greenhouses  and  
using propane and natural gas.  But perhaps the "number  crunchers" in  
our group could calculate the heat and CO2 from a  TLUD-FA with perhaps  
a 30 gallon capacity burning chips or  pellets.  And then match that  
with a size of greenhouse in some  appropriate climate/temperature zone.

If safe and appropriate, perhaps  5 or more TLUDs could be prepared and  
(automatically?) ignited at  specific times through the night.  The  
concept could be  scalable within the range of small to medium  
greenhouses.

If  interested, please respond initially via the Stoves listserv and   
also to the addresses of this message.  If there is interest, then  a  
working group could be created off-line from the  Listserv.

    Paul, 
    How soon do you want to start the experiment?   I am taking possession 
of five acres tomorrow through a lease purchase to build  a new plant 
nursery. I have little time to rebuild my entire little greenhouse  complex this 
fall due to the urgency of my forced business relocation. 
    My plan is to quickly construct one or two small  greenhouses in order 
to preserve my tropical plant collection and start some  annuals for next 
Spring. Next summer I hope to reconstruct the large greenhouse  bigger and 
better than the old version you saw decaying a few years ago. 
    Any and all ideas for collaboration will be  considered. Until the 
entire site is excavated and sub drained only small,  portable, temporary 
structures will be constructed. I have considered purchasing  one of Tom Reeds 
larger camp stoves for experimentation unless someone has a  donation TLUD 
stove. I am on a limited budget while restarting my landscape  business from 
scratch. Ideally I need a stove that will burn slowly unattended  all night. 
    Plenty of fuel will be available from clearing the  site as well as my 
small firewood selling operation. I had well over 30  cords of small trees 
sitting stacked around a friends farm  in northwest Miami County last Spring. 
I bet most of it is still there for the  taking. 
    Anytime you are driving through Dayton please call  and arrange a visit 
to my new site. It's only a mile from I-675. Less than  5 miles from I-70.  
The new site will be very unimproved and  primitive for some time, bring 
boots.
