Hi
@Dico29 I did it once. A good way to prepare this potassium-rich fertilizer tea is to boil 3 banana peels in 1 liter of water, adding a little sugar. Once the mixture is cold, we remove the banana peels and use the resulting liquid to water our marijuana. This tea is applied during the last six weeks of flowering. With this you will get up to 20% more fattening in your buds. You can also do it using honey, or sugar cane molasses. Good luck mate 👍
