Hi, after 5 hours of pointless reading and googling here I am! Most articles about this subject are nonexistent, irrelevant and with very little information, or strictly about producing energy on small or a massively industrial scale. My needs are simple and I hope someone can enlighten me with knowledge to prevent my dumb self from making mistakes! Need for zero odor, maintenance free, indoors storage, safe for humans while stored. First, in the even I only fill up a 5 gallon bucket(not the cheap one from a hardware store, but a kind used for fermentation that can be properly sealed), can I leave it sealed for the entire process if all I put is green matter? I would not be introducing any complex materials like fat or stems that are near that stage which are hard and woody, while also filling the bucket fully to the top with rain water. So second question, how long would this process take approximately? Are there very accessible( no additional stuff to buy but something found in often used household materials) things I can introduce to accelerate the process and promote the proper environment for the best possible compost tea? A lot of articles claims different things everywhere, some claim methane gas will not even be produced in a submerged setting or even just very high humidity levels as long as the acidity levels are very high, any truth to that? Because I feel like no one wants methane gas inside their home. If such is the case, will the 5 gallon bucket pop itself open from excess pressure buildup and create danger? I am highly aware how dangerous the results can be, but many claim pretty much anything at this point. Some say that if the anaerobic process is completed, all harmful contents will be neutralized and ready to use, while others claim it will need to sit in open air outside to neutralize for an incredibly vague amount of time. As you can see, trying to do something that simple nowadays with access to internet makes all information borderline mythological with no reliable source. In advance, thanks for YOUR TIME reading this, and if any guidance, all is welcome. This is a shot in the dark for me, as dumb as I am with my questions.
