Is there a spray to make cannabis more potent?

I heard there is a type of spray that when sprayed on the buds it will make it more potent by forming more THC crystals when its dried up.

i mean, maybe a misting of ethanol on the drying/curing buds may work. by extracting the THC to the outside of the leaf, then evaporating, thus leaving more resininess on the outside of the leaf, and possibly decarboxylating the weed before hand, thus increasing the potency. though this is only theory, it seems plausible. only you can decide.

you may also try extracting the crystals through kief, and resprinkling them on some other weed to increase the overall potency. along with the same for some hash oil. Spray green dragon on your curing/cured weed. not the extracted weed. this doenst really save money, but it does save your lungs because you smoke less.

Yea foliar feeding. Purple maxx and snow storm are so posed to do that, im happy with the results but cant say anything definitive unless i do a side by side run
