So in the video he uses .. maybe it is more concentrated labs? Or is it just a product that bas sells so they use it also? Lol so I can just try to go 1:1:1:100 whey (labs), sugars, plant material, water and I should be good to go?
if you mean his bucket of goat whey then it's probably the same story lol. I'm no expert but I'm positive whey would be beneficial for a garden regardless of how it's made, all that protein's gonna become nitrogen afaik, and it would make the environment more friendly to friendly species like LABs and yeasts.
if you mean the bottle he called LABS then yeah I think it could be a product placement lol. Although it wouldn't hurt to add a little diversity, and if his goat whey wasn't curdled by LA bacterias maybe he just wants to he certain has a healthy population of them. But that said....
I curdled it using white vinegar and lemon juice though. So maybe this will not work.
it should be helpful no matter what. The fact the whey came straight from the goat means it should have a great population of microbes from the goats own body. I don't know how lacto bacillus strains handle already acidic environments since they expel lactic acid as waste, but adding the acid afaik doesn't get rid of the lactose they munch on, you just wont have a visual indicator to know when/if they've done so.
