My recipe is: 5 Gallon Bucket filled up with fresh cut stinging nettle to at least 2/3 of the bucket to improve the mix i add comfrey and put some common horsetail (dired plant/amount around 200g) in it and this has to be filled up with water and placed in the sun or under warm lightsource for around 1-2 weeks and stir at least once a day. Not really recommended to do this inside its smelly as helly but you can add valerian extract (not the root extract, the flower one) to keep it 'low'. This is most likely done in summer but i guess will work right now too but takes longer. Mix it 1:20 or 1:10 ratio with water depending on the plant and there you go. In flowering time i add guano tea and/or stone flour. Thats it. I hope this answer fits the question as i am not sure if you meant this by asking what i do, but thats what i do.
I may try horseshit outdoor next since i can get fresh and compsoted both from the dumpspot. But right now i stuck to reuse my soil because its already here and i am lazy. But i think you can definitely go for a horseshit grow even if fresh. I would mix it with the soil, and it will be beneficial through the fact it got so many bacteria innit.
If there is some further questions to the recipe i am willing to share it all. If not for the smell i think you will love it!
I think it can, ill try horse shit sometime but havent until now. I hear i should be composted if you use the shit in soil but some people make a lower layer of fresh stuff outdoors when its cold the rotting process will heat the soil and benefit the roots if they are not in contact from the beginning. @Dr. Babnik you may try and tell me how it works!?
if it still stinks it still delivers, may lose a little potency, not sure about that. (and mine was made months ago still stinks and i still use it)
