So these scientists figured out in 2017 that besides sugar, ethylene is the other major regulator of plants' sleep cycle. Do any of y'all have a trash can near your grow, or perhaps some bananas in a kitchen near your grow? If so, you are speeding up your plants circadian rhythm and causing them to ripen faster! Might be good for certain cases, but for most of us who want out plants to keep bulking up as long as their genes will possibly allow, this is really bad! I actually sent these folk an email letting them know how the sugar blocks ethylene from speeding up plants' ripening phase. As long as the microbes are either being fed sugars by the plant or by you the grower, then they will create certain compounds which protect the plant from having a stress reaction to the ethylene and therefore continue to bulk up as they normally would. So if you are doing an apartment grow or home grow with any ripening foods near by (or any sources of ethylene) nearby, your plants are at risk of being stressed by the gases. Keep your microbes alive and active till the end of harvest and it will save your plants from experiencing this effect just discovered by these scientists.
