I have been dealing with various genetics herming on me over the years. I have addressed many variables and non of which have resolved the problem. So now i am going to fine tune things just a bit. This is where all of you farmers can help me out... once again.
I run a sealed room that does not get fresh air that often because i fear that i will introduce pathogens. It has happened with Powdery Mildew and such because it is difficult to treat the intake of air. I also use a propane burner which i plan on ditching once i can get a controlled reading.
I am searching for an O2 sensor and an Ethylene sensor. I was hoping not to spend too much on these tools but am willing to pay the price if that is what it comes to.
This is a great article that keeps things simple. http://www.hort.cornell.edu/mattson/leatherwood/
This is a great article about various detection methods.
Conclusion: "Several types of sensors for monitoring ethylene production in plants were presented. Ideally, a sensor should monitor ethylene quickly, sensitive, with high selectivity and should be available at low costs. Unfortunately, such a sensor does not exist at the moment"
Ethylene, a small colorless, odorless gas composed of two carbon and four hydrogen atoms (C2H4), is responsible for both beneficial and undesirable effects in greenhouse crops. It can prevent flowering, shorten internode length, increase branching, initiate fruit ripening, trigger leaf and flower senescence and abscission, cause leaf chlorosis (yellowing), and improve adventitious rooting. Some crops are relatively insensitive to ethylene while others are very sensitive.
Dont know the price point yet but this seems to be the unit.
This unit is overkill yet it allows you to see all of the variables such as Temp Co2 ... at the same time as seeing what the ethylene levels are. I am unclear on how the air is supposed to be moved through the unit.
The next unit seems good yet it does not allow you the ability to connect to a computer to see what your numbers are at various times
