Is that a PGR? Safe? Sounds cool. Pics coming, not the easiest thing to do in there.
Plant hormones can be grouped into five classes of compounds: auxins, gibberellins, cytokinins, abscisic acid, and ethylene,
Ethylene is the only known gaseous plant hormone. Many plant organs synthesize ethylene, and it moves readily in the air surrounding the tree. Usually, ethylene has an inhibitory effect on plants. It promotes abscission of leaves and fruits, inhibits shoot elongation and favors caliper development, and, along with auxin, inhibits lateral bud development. On the other hand, it can break dormancy in buds and seeds and causes rapid ripening of apples. In apples, ethylene is involved in the transition of fruit from being physiologically mature to ripe. Once exposed to ethylene, their storage life is shortened.
when natural plant hormones are chemically synthesized they are called PGR's. I dont know if Reverse is chemically synthesized or not. used in fruits and greenhouses, storage etc. the gas is probably safer than inhaling the smoke from dried dried leaves and flowers burning
