this is new to me,ive never used yeast to ferment,also using the flask does it make the process faster?
my normal method is 1:1, equal weights of plant and molasess,i have used brown sugar but find it gets hard in bottom of my mason jars,also using molasses i dont have to worry about my jars pinging as much.
i use 5 gal buckets with sealed lids,paint buckets,they have a second small lid i drill 1/4 inch hole in that small lid and run 1/4 tubing to a coke bottle with same 1/4 in hole,run tube to bottom of the bottle and fill half bottle with water,the gas off if the fermentation makes bubbles when it is done bubbling it ready for use.
it can take up to 2 months though depends on weather,now the OHN that gets expensive to make ,unless you have cheap vodka to spare hahahah that is a 6 week process alone,every week your refreshing the vodka.
i used all my stuff which i made from my garden veggies,lasted 2 years did very well as far as did it do better i cant really say the heat is a bitch on any plant life were i live,but cost wise you better believe it better.
im convinced on one thing comfrey and nettle can feed any plant and that alone is all you need,that stanky ass shit is some potent stuff and plants love it,i run with it in my outdoor veggie garden and my tent ,both did very well considering the cost of making it,pretty much the cost is for molasess all plants are free just pick the new growth in the dark .for the one fella that ask why use mollases,because the bacteria feed on it,if you dont believe it ferment with it and jar the feed up as the weather changes the activity is known real easythe lids ping and you have to go burp jars just like your weed
