Kombucha for ph down and composting with lab

Anyone ever use this in their plant water, loaded with bacteria and yeast and cheap to make. Would bring down ph pretty fast as ph of kombucha can get as low as 2 I believe.

Also thinking of using kombucha fluid in my lacto bacteria (LAB) inoculated compost to introduce another form of yeast/fungi to break down plant matter.

Anyone ever try this?

I've used my vinegar heavy kombucha frequently for ph down. It's almost too effective! Those extra enzymes can't hurt.
I can't speak on the 2nd idea, I would think the LAB would just take over, not letting the other bacillus colonize? Not sure if the strains thrive at different PH levels. Looking forward to what you learn with the 2nd test!

I've wondered about this, and was eventually going to give it a spin. Been making 'bucha for a couple years now.

Good idea on using that batch that's sat too long for Ph down, definitely keeping that in my bag of tricks.

I have thrown scobi into the compost without issue. Let us know if you guys learn anything with your trials.

I use em1 (activated labs w/ yeast) as my pH down essentially... it has a pH of around 3.5.

But I dont see why kombucha would be much different. It is very similar to em1 in that its a bacteria/yeast fermentation.. the only difference being the lack of lactic acid bacteria.

I believe the probiotic nature of both em1 and kombucha are what is truly important, rather than the type of probiotics each carries. You might be onto something here!

If you've not checked it out yet, you should look at Green's Probiotic Method in the "Organics" section. A lot of good info on growing with probiotics, and some of it may translate well to your kombucha idea.

Let us know what happens, as im thoroughly interested in how plants/soil microbiology react to the use of kombucha.

I threw in the kombucha into the lab compost tub a few days back. It's not going to tell me completely because the lab has been in that tub already for 3 weeks. I'll need to do a side by side with the same material.

What I do know is both lab and kombucha cultures feed on sugars, both are roughly the same ph, and that compost is full of sugars broken down from more complex carbohydrates.......at least me thinks.
