Can plain greek yogurt be used in any way for cannabis?

Kind of a random question, my apologies, but these are the things a stoner ponders randomly while eating breakfast.

Every single day, I eat berries and greek yogurt as part of my daily routine. As a result, I end up with a fair bit of leftover bits of plain yogurt in the bottom of containers that I inevitably just rinse down the drain.

I recently read something about using leftover milk to make some kind of LAB product which got me wondering, is there anything I can do with unsweetened high protein plain greek yogurt as well? Any kind of strange science fermentation? Something I could either later use as a foliar or a soil feeding?

Just trying to repurpose it and not wash it down the drain, hopefully this makes sense!

Compost is helpful, but I’m not sure I would put waste in my pots. It needs time to break down to be useful to a plant.


Thinking the same thing. Drop it in a compost pile.

SADLY i buy my compost (both worm castings vermicompost and traditional) from black swallow living soils as I don’t have the land or space available to do it myself… they also do it way better than i could, giving their worms specialty diets and screen them afterwards with expensive equipment etc… I think I pay around $20 for a huge farmers sack that I’ve barely made a dent in!

I was thinking maybe not so much as just dropping the yogurt into my soil but maybe doing some kind of bacterium microbial mumbo jumbo … In passing I saw an article about Korean Natural Farming and they use milk leftovers to create some kind of nutritional sprays and soil drenches… Appreciate all the replies!

This place is a great wealth of information!!

That being said. Yes you can use Greek yogurt for your plants. It’s a probiotic! I can’t say what the ratios would be but I will 100% say if it’s healthy for a human it’s healthy for a plant.

Using may not be conventional so I would say research on using it properly. Weather it be in a compost pile or apply to the soil/foilar.

Knf uses milk and rice wash water to make a probiotic. The Greek yogurt has already been through this process ( not how knf does it but industrial way ) so I personally wouldn’t try to ferment it again.

Again this is a great place to learn! So after all that I’m going to add if you are using synthetic nutrients i wouldnt try to use the yogurt. Maybe you can clone or start a new plant and test it out?

There are many different micro-organisms. Each is ideally suited for a specific thing they like to digest.

Many people make a lot of noise about ‘Lacto-’ organisms but keep in mind that those organisms are designed to digest milk.

You can use Lacto-stuff to seed your stomach, but it only truly helps in terms of digesting milk.

There is also a wide array of fermented bean cultures with organisms that digest beans.

Consider worm castings. Worm castings are from earthworms. As worms eat dirt their stomach juices coat the dirt and digest it enough for the worm to get nutrients from dirt. As it flows out from the worms it is wet and slimy, coated in worm stomach fluids. After worm castings have been allowed to dry, they are still loaded with all the soil-digesting micro-organisms as needed for digesting dirt.


I bought a few things from black swallow last month! Got their trio compost, rice hulls, kelp meal and some charged bio-char. Trying it out in an organic soil in some outdoor SIPs this year.

Awesome! They are local to me, I shop there in person… really nice guys and always happy to chat with you, the exact kind of business I want to support

I am a novice and don’t know how to use most of the stuff though, lol. I have that same trio compost you have , and their worm castings as well!

for kelp though I bought their liquid version, the stella maris extract

and i have no clue what bio-char and rice hulls do!

cheers !!

Put some strawberries in it, good for the munchies :yum:
