Diy N sources

I’m experimenting with DIY inputs and looking to expand my nitrogen sources beyond standard bottled feeds. If you’ve used ferments, hydrolysates, or other homemade N inputs successfully in veg, I’d love to hear what actually worked for you and how you applied it.

In soil you can add used coffee grounds for slow release nitrogen. A few tablespoons mixed in 5 liters of soil. Turns a waste product into plant food.

Alfalfa pellet, cheap cattle feed (horses normally) and you need nothing else other than this in veg. 1 hand full in water after a day it turns brown, dilute that again and use.. Magic stuff. Triacontanol in there too. Spiralina like ultraviolet said is, also chlorella, Chlorella is a nutrient-rich microalgae used in agriculture as a natural biofertilizer and biostimulant, promoting better plant growth, stronger roots, increased photosynthesis, and enhanced disease resistance by supplying amino acids, vitamins, hormones (auxins, cytokinins), and minerals like iron, phosphorus, and potassium. Provides essential macro- and micronutrients (N, P, K, Ca, Mg, Fe, Zn) and organic substances that improve soil health and nutrient uptake. Hope this helps mate..

Have a look into Spirulina Supplies essential micronutrients (Zn, Mn, Cu) and macronutrients (N, P, K) to plants. In sizeable amounts. Wouldn't be surprised if they made it a weed and outlawed it. It's that good. Spirulina in general is highly digestible and breaks down much faster than most plant materials making it great to work with. Gluck Yan the man.

Ich habe Aloe Vera Barbadensis miller fermentiert. Zuerst die Blätter ausbluten lassen, dann die Stachelränder großzügig entfernen und pürieren. 1:1 mit unverarbeitetem Vollrohrzucker vermischen und 6 Monate bei 16 Grad Celsius fermentieren lassen. Sehr ansprechende Ergebnisse, vor allem zusätzlich zur Blattanwendung und bei Mehltaubefall sehr wirksam. Fermentierte Cannabispflanzenteile werden auch noch getestet, als kompletter Growdünger sollte das perfekt funktionieren. Zur Blüte wird ein Ferment aus Kiwi und Banane verwendet, ebenfalls hergestellt aus 1Teil Obst und 1Teil Vollrohrzucker.
