i've been yahoo'g and i'm not convinced stinky hemp is a pH issue. i couldn't find ANYTHING that linked pH to ammonia.
but i DID find some interesting stuff that may help (or confuse the matter even more! LOL)...
quoted from http://skepdic.com/comments/urinecom.html
in a discussion about "urine therapy", another subject all together, but this quote may be of interest to us...
|One minor little, but rather common, mistake in your presentation: human urine as produced by the kidneys and freshly voided does not contain ammonia (the urine of some other species does). However, if human urine is exposed to air for any length of time, airborne bacteria will break down some of the urea into ammonia. So it's only "stale" urine that contains ammonia.
along the same lines, this page explains what causes strong odor in human urine (http://www.madsci.org/posts/archives...3402.Gb.r.html
). it says
|Urine in a container acquires a pungent odor as the urea breaks down to ammonia due to bacterial action.
i've never experienced stinky hemp, but since most of my stash is hemp, i
: the subject in case i ever have a problem. it seems like most everyone with stinky hemp says that the hemp didn't stink in the beginning, it happened after a few months.
assuming all this information is accurate, i'm going to go out on a limb here and make a hypothosis about the cause stinky hemp dipes...
a) airborne bacteria is breaking the urea in the diaper into ammonia, assumably while the diaper sits in the pail awaiting wash day - maybe the length of time the diapers are sitting is a factor(??)
b) the urine/ammonia is getting trapped in the super-absorbing hemp fibers and not being completely washed out of the hemp diaper
b) over time, the stale urine/ammonia that isn't washing out of the dipes, builds up in the fibers
now what i can't figure out is why some people have stinky hemp and others don't. assuming my buildup theory is correct, WHY isn't the urea/ammonia getting completely washed out??? is it the amount of time their dipes are sitting in the pail (assumably making higher levels of ammonia the longer the dipes sit)? is it the efficiency of their washer? are some detergents better at washing the urea/ammonia/bacteria out of the dipes?
i've also found repeatedly that ammonia breaks down easily in water. maybe this is why repeated washing without detergents seems to rid the ammonia smell. or maybe there really is a "detergent buildup" making the situation worse (kind of like your carpets getting dirtier faster after shampooing). maybe there is a water hardness factor here and hard/soft water breaks down the ammonia faster/slower.
