dude yes!!! try this, been wanting to know if it works. take a freshly havested bud on a stem and put it in a little water with some coke in it, it will suck up the coke water just like flowers in a vase. FFD did this but with food coloring and it worked!! tell if you try this if it worked!!
but dont do it while it growing that would waste it you must get the bud to suck that stuff up right after harvest. it worked with food coloring and the bud turned blue when FDD did it but he said the bud tastes horrible, but maybe your bud will taste horrible too horribly numby
Warning: Don't waste your money! the roots won't uptake the chemical makeup of the soluble coke not to mention that the coke isn't PURE. The only way to put it into the plant is by injection into a stem. Make sure your stem is hollow and inject it into the hollow part of the stem using a very thin syringe.
