Growing a SCOBY!
Alternative Lifestyles and Subcultures
i have been brewing for a while now, and its really really easy, jeg can actually grow your own scoby from a store bought combucha tea, jeus make sure it's only kombuch not added any flavoring:)
1: heat 1 liter of water, ad between 75 and 90 grams of suger and stir until no suger left in the pot.
2: just before the water starts boiling add 1 or 2 teaspoons of organic green tea, and take the pot off the heat to cool for abot 15 minuts, then you filter the tea so that you are left with only the sweet tea.
3: now you let it cool down to room temperature, and put it in a big glass jar.
4: add about 100 - 150 ml. of your store bought kombucha to the glass jar and cover it with a cotton cloth
5: 7 - 20 day and you have kombucha depending on the wether 
remember it is not the size of the scoby that determins if its ready or not, so you will have to taste it once in a while, i recomend using the "straw n thump" methode ;D
always make sure to have very clean hands and equipment when brewing kombucha, that way u usually avoid mold, allthough in most cases the scoby is self healing (it can get rid of the mold it self, if its only a little mold)
and keep it away from extreme heat and direct sunlight!
But to the point, that is the way animals keep their hair clean, is rub themselves all over dirt or sand, which soaks up the oils from their skin and hair, and the dirt kinda falls off. I have seriously wanted to try that! (I knew it would get laughed at, but hey, I've been at the end of my rope, washing new-ish dreads is a pain in the a__!) So, I have not heard of this product, but I will remind all who swear by dreadlocks shampoos, the bars all CONTAIN CLAY! That could be a good thing, could have been what got stuck in my hair, I don't know. My son had a lot of dreadie friends and said lots of them use dirt to wash their hair. He thought that's how you "have" to do it!
