DIY organic amendments with household products

[Kinezokyprios]

You can use most of food leftovers but stay away from all dairy products, they will damage your plants. If you need extra cal mag a cheap and effective solution is go to a pharmacy and buy magnesium milk, which is cal mag for humans that have stomach problems and the like.

Hi guys!

I've been thinking more and more about growing without any chemical bottled fertilizers. I've just purchased 2 sets of granular organic fertilizer in the local gardening shop ( NPK 8-3-6 and NPK 4-8-10 for veg and bloom for my next grow. I think I will try to powder them (around 40g of each for a 2 gallon fabric pot) and mix with the soil when germinating.

Recently I've been looking for some simple house products I can use as supplements. I'm drying coffee grounds from my daily coffee, rich in N, about 2%. I'm keeping the egg shells I use cooking, rich in cal and mag. I'm drying some potato and banana peels, rich in K, about 35-40% I believe and residual N and P.

For the egg shells, potato and banana peels, I will powder them when I'll get enough collected to make it easier (and faster) fornthe micro-organism and bacteria in the soil to process it.

Wanna know if any of you ever used this kind of simple ammendments, if they disolve in time for the plant to use theese nutrients.

And please share if you know about any other household things like this you can use as organic fertilizers!

Happy grows

If you mix the dry fertilizers 50/50 you will have 12-11-16. If it's slow release don't powder all of them, it's nice to mix slow and fast release so the soil is not too hot. 12-11-16 should work fine for the lifetime of the plant if it has some micro in it. Potassium is good.

I add two spoons of organic granules (NPK 7-6-12 + mag 2, a typical rose organic fertiliser ) and 1 spoon of oyster powder cal mag before planting. Mid flowering I add 1 spoon of the same granules minus the cal mag (roots will hardly reach the bottom.layers of the pot where cal mag lies, by this time). That would do for a typical grow in fabric pots with up to 7 litres of soil. Sometimes, depends on the soil and how much ph will rise by the cal mag, I would add 2 spoons of used coffee grounds to regulate ph and to add some N for the vegetative stage.

I was thinking about buying some guano 1-10-1 for flower boost. I've seen gaia green and it seems amazing but they don't ship to europe, no way of getting it here.

I used my coffee grounds, 1 tb spoon for a 2 gallon pot as top dresser before watering. Just let it dry and spread it well to avoid mold issues on the soil, it worked for me so far

Let it mold. .
Why dont you start a worm farm and a compost bin? I have both in my home and there is no smell if you dont let it go aerobic. I am also colonizing bacteria and fungus through the implementation of a couple recipes.
Also if you add vinegar to your eggshells you can make it available to your plants.
Eggshells ground up and added to soil may provide calcium eventually but not right away to any significant degree. Worms live all that stuff. So does compost.
