Coffee Grounds Used For Growing Medium

highonbud · Mar 8, 2011

Yes I said it Coffee grounds used to grow, every batch of coffee i make i save the used coffee grounds in a can, these can be used for fertilizer in the yard. here is my question though can you use coffee grounds as a grow medium? would the caffeine create more resin? :leaf:

post your input, thoughts, opinions, concerns, or just shoot the shit :leaf:

I'm always looking for new grow techniques and I've been using this on the yard for some time

caffeine won't affect resin, and my guess would be that coffee grounds wouldn't work as a growing medium (possibly from texture/density/air/water flow, and toxicity)

you could grow some good columbian!!!!

I have a feeling they are too acidic to grow in.

Start a worm bin. Worms love coffee grounds and the castings are great to grow in.

Coffee by itself is much too acidic.

I may do that, Buying worms for fishing is getting expensive spending 5bucks a day. I like that idea. I may just do that. a worm bin with layers of newspaper between dirt is also a good way to go I've heard.

what about worms in the pot your plant grows in? would it do the soil good?

Someone answer this!! ASAP!! I like this idea, but im a rookie so its prob a terrible idea. Usually my pot growing ideas just turn into jokes, but I guess thats part of growing up in the cannabis adventure.

Yess - the worm in your pot will continue making the soil more airy due to the tunnels it creates while dumping gold nuggets in there - definitely. Feed it with some leaves and stuff to make sure it has something to eat.

you are aware that coffee grounds need to be composted first right?they are very high in N and if not composted first your going to burn the hell out of your plants

Kevin A · Apr 5, 2011

Thanks Brimi. Looks like I have to do some research on "the benefits of using worms"

Wetdog · Apr 5, 2011

I have 2 worm bins and worms LOVE coffee grounds.

AFA worms in the grow pots, I've found worms many times due to the fact that my castings are full of worm eggs and they hatch in the mix.

I have never found worms at the end of the grow. For whatever reason, they just don't survive in the growing containers.

from what i've read, worms don't do good in grow pots.. the soil that it takes for worms to thrive and the soil it takes for weed to thrive are two very different soils, so, do you want to grow worms or do you want to grow weed is the question that you must ask yourself...if you want the benefits that worms give, simply add some worm castings to your soil .....

I regularly pad used coffee grounds into good soil for outdoor gardening. Used coffee grounds is not acidic.First, you have to bake it dry or vermicomposting before you can use it in planting other wise it'll composted in your medium along with the living roots.

Coco peat is the same, exactly the same, consistency as coffee grounds. Why not mix the two with a little perlite and see what happens?

highonbud · Apr 8, 2011

Snow crash that may be a good idea

I use my old espresso grounds. So far no negative effects.

Could use low-acid coffee. It does exist, though it's probably a fair bit more expensive. I'm guessing different brands and types of coffee vary fairly dramatically on acidity levels, depending on the soil the coffee was grown in, the genetics, conditions, etc. I'd even bet you could find a brand of coffee with proper natural ph level for ganj, and use that as a base nutrient source in a grow medium mix. I'd assume that coffee grounds no matter th ph can't be used as the primary medium itself, being too hot with nutrients; perhaps it could be used in a similar way to super soil though, with some additives and perhaps diluted with perlite or such a bit.

I use to sprinkle coffee grounds on top of my soil before I watered every couple weeks during veg with no negative effects.... Coffee grounds are loaded with nitrogen...

sso · Nov 15, 2011

i agree i would compost the coffeegrounds first

and i dont think adding worms to the soil would be a good idea, the worms would soon escape in search of better.

or die.

Ive always wondered about coffee and weed. One of my friends said he new somebody who grew a batch of plants almost entirely on coffee/water mix. Never believed him tho. Seems more feasible to give watered-down coffee grounds to the soil for extra Nitrogen.
