Plants that get fed a lot of sugar in the last few weeks of flower also are much stickier than normal bud. Like I use molasses the last few weeks, and my herb is really sticky even completely dry.
I'm pretty sure it's not the sugar. As the sugar in molasses doesn't get eaten by the plant.
It's the micro nutrients in blackstrap molasses that makes it good to give to your plants
I also used molasses on my grows
Stickiness is a result of what the above people said: essential oils, drying/curing process, resin/trichomes (genetics that determine oils/resin)
Asking why your weed is sticky, is like asking why your weed is good.... It's not one thing, but many things working together.
>>> Unless it is un-naturally sticky, like glue or some shit. People are always spraying shit on weed in the UK i hear. I've never seen it but I don't fuck with bullshit circles like that. There is enough money to be made selling good, clean strong weed.
I think its the "resin"...if you dry/cure it enough though it'll stop being sticky
One thing drying/curing does is let the sugars break down into THC / other chemicals to break down. (that's why your shit gets stronger and stronger for the first 2-4 weeks)
Another thing it does is let chlorophyll leave the plant , leaving the trichomes/resin which contain the terpenes (basically the smell of the weed). This is why Your weed smells great, then you cut it down and it smells like hay, then you cure it for 2-4 weeks (at least) and the smell shifts from lawn trimmings to DANK weed.
Also, the slower the drying the more chlorophyll escapes leaving smoother smoke, this is why a quick try tends to yield a harsh grassy smoke if someone didn't know that
