marijuana seeds ethylene

I got 12/12 female from bag seed using mostly bananas but any ethylene producing fruit will work. Heard of people soaking peels in the water they feed with. Heard of diluted ethylene topical sprays. Heard of treating the seeds prior to germination with ethylene. this works. The science and my personal experience is there.

For sure though by the time you are getting read to flower the plants sex is already determined, unless you stress her out and she goes all hermie on ya

You are going to get many different responses on this one i am thinkin. I am of the, it is decided when the plant is in its seed example feminized seeds.

Many people will argue that the banana method is what you need to do when you germ.

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. http://aob.oxfordjournals.org/content/early/2012/12/12/aob.mcs259.full
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.
