Coffee Bowl

Coffee Grounds Substrate

Start with used coffee grounds, these were recycled from a Donut shop.



Rinse until the water runs this clear.



Drain as much water out as possible. I used paper towels



Spead on a cookie sheet and place in a 200 degree oven for 30min to dehydrate. Stir and re-spead at 10min intervales to speed dehydration. This will help solidify any remaining oils & caffeine left over from brewing & your rinsing.

The grounds will be a light brown color.



Plant as you would any other substrate (sprayed prior to planting)



Wet, the grounds look deep black and are very uniform in size. (Temp rock work)

Coffee Grounds - Contain about 4% nitrogen, 1% phosphorus, and 3% potassium.

"Contrary to popular belief, coffee grounds are not acidic. After brewing, the grounds are close to pH neutral, between 6.5 and 6.8. The acid in the beans is mostly water-soluble, so it leaches into the coffee we drink."

Wow I didn't know you could do this, very neat

This seems really cool as I drink a pot of coffee every two days. So I got lots of extra grinds! It'll be funny if you put in fish/shrimp and they start whizzing around from the caffine. But I think most likely they'll just drop dead 3: !! How are you taking those photos, they look really vintage haha.

Sorry about that, "vintage" cell phone pics.

From what little I know of coffee roasting, the more you roast, the stronger the flavor, but the lower the caffeine amount. Does baking at 200* for 30 mins help eradicate any caffeine remaining after the rinse then?

This is an ingenious idea. What do you plan on for livestock?

I noticed that with each rinse less oil film was seen on the rinse water. I'm not as concerned about the caffeine as that should have been mostly removed in the brewing process. My thought on dehydration was solidify any remaining oils that give ground the coffee smell. I found very slight coffee smell after the drying.

In hindsight, I should have rinsed a small test to see If I was correct.

I've got an idea or two, need to do some or research 1st.

The Crypts you send are doing well in the "Toxic Ten" One in the back toss up a new least overnight.

It's those cold Chicago winters that drives these quests for new and improved ways to do the same thing. A lot of folks use their coffee grounds in compost and it the yard, at the moment I can't remember the exact use but going green, recycling, and Yankee ingenuity are all good things. I'll be curious to see what results come of all these experiments. Plus at the least it's great entertainment.

Using coffee grounds for tomatoes, rose bushes & house plants was something Grandma taught my father.

Hobbies are supposed to be fun, if I make a few people smile it's worth the effort.

Interested to see how this turns out. I throw my coffee grounds in the compost, never thought to put them in my fish tank though!

[driftwoods]

Way cool intrested to see how this turns out.

Who would have thought 3 Rocks would be so aggravating. I've re-scaped it three times, split rocks twice but, I got it!

Now, I need to leave it alone.
