Sure, I am growing them myself to have a cheap and reliable source of clean herbs, besides proofing that I am able to. So being able to produce as cheap as possible is just another proof of proficiency.
I have checked the bottle label, it says 2.6% N, 1.9% P and 3.6% K plus some further elements.
It surely is quality fertilizer but yet again massively overpriced, the same goes to other brands too. We are talking like 10 cents worth of base materials per liter or so and it's far away from the complexity of a car, just have a look at the number of people of Hesi, it's extended family lol.
So, did anyone mix it themselves or at least found a much cheaper solution than buying those pseudo cannabis mixes?
PS: You can grow plants in aquaponics with more or less fish poo, no need for getting a degree in something
