interesting thread
i have been looking into fermented plant juices,so i will contribute something to this thread
http://nfe.localgarden.us/index.php?title=Fermented_Plant_Juices
i have always just put the butter,water,weed on the stove and boiled it for about 20 min
put it in the freezer and when frozen seperate it
or u can wait til its almost frozen and dump most of the water off
i use a homemade aeroponic system,i like it
but as mentioned before,watch out for power outages
with ebb and flow this is not really an issue
i find myself misting the roots when the power goes out
i would pick the balls off and continue on
the plants that just showed sex CAN get pregnant,so look for signs of pollenation
within a few days there will be withered pistils and swelling calyxes
