Because its a free source of available nitrogen thats found in many reputable fertilizers under different names. Your comment is kinda like saying why would you use poop from a bat? Or why would you use decayed fish guts? Those things are"gross" too but they solve the problem the plant needs to thrive. Do you belive aquaponics works? Ok well you have 4030 posts since aug 12 so i figure you know that aquaponics is just fish poopin and peein in the water and plants enjoying free nitrogen as a byproduct. You understand what organics are right? Organic nutrients are any nutrient that must be acted upon and processed by a biological life process before being available , in such form, that the plant can recognize and assimalate. Thats what you said right? Its not like the plant is going to be soaked with piss, luigi has only used bloom nutes with very small levels of N. doesnt want to spend a fortune and is running out of time for the plant to utilize N while growing taller or bigger in his lst environment. 100% urine is bad, diluted urine is good. Mother earth news, scientific america, and countless tree huggers all cant be wrong. Ive never tried it. Im also on my first grow, its going very well with no pee added. I dont claim to be an expert on anything except sleeping in. I just read a bunch of data on cheap available sources of nitrogen and urine popped up all over the place. I doubt luigi will pee in his nute solution, if someone told me to before i read what i did in the lastcouple days id have laughed at them. It has a little to much salts from what they say but i intend to try it out. People told me LED lights dont work worth shit but look at my basil plant under it. Thats not the only plant that lights veged with great sucess. Im just tryin to help luigi out. Some haters were talkin shit about his plants and i dont think that thats what riu is all about so i stuck up for him and want his plants to do well. Oh ya, i dont think this is the exact fertilizer your useing but its miricle grow none the less so id assume the ingredients are pretty cross utilized....
Miracle-Gro Ingredients
The All-Purpose Plant Food has a
15-30-15 ratio, meaning that there is 15% Nitrogen, 30% Phosphate, and 15% Potash.
The primary ingredients in the Miracle-Gro powder are as follows:
• 5.8% Ammoniacal Nitrogen
• 9.2% Urea Nitrogen
• 30% Available Phosphate
• 15% Soluble Potash
• 0.02% Boron
• 0.07% Copper
• 0.15% Iron
• 0.05% Manganese
• 0.005% Molybdenum
• 0.06% Zinc
Derived from: Ureaform, Ammonium Phosphate, Urea Phosphate, Potassium Chloride, Boric Acid, Copper Sulfate, Iron EDTA, Manganese EDTA, Sodium Molybdate, and Zinc Sulfate.
I believe that you are useing urine on your plants right now unknowingly at around 9.2%.

Urea or
carbamide is an
organic compound with the
chemical formula CO(
NH[SUB]2[/SUB])[SUB]2[/SUB]. The molecule has two —NH[SUB]2[/SUB] groups joined by a
carbonyl (C=O)
functional group.
Urea serves an important role in the
metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the
urine of
mammals. It is a colorless, odorless solid, although the
ammonia that it gives off in the presence of water, including water vapor in the air, has a strong odor. It is highly soluble in water and practically non-toxic (
LD[SUB]50[/SUB] is 15 g/kg for rat). Dissolved in water, it is neither
acidic nor
alkaline. The body uses it in many processes, the most notable one being nitrogen excretion. Urea is widely used in
fertilizers as a convenient source of nitrogen. Urea is also an important
raw material for the
chemical industry. The synthesis of this organic compound by
Friedrich Wöhler in 1828 from an inorganic precursor was an important milestone in the development of organic chemistry, as it showed for the first time that a molecule found in living organisms could be synthesized in the lab without biological starting materials (thus contradicting a theory widely prevalent at one time, called
vitalism).
I really hope that this info doesnt change the direction of this thread. Its about luigis plants not pee and im not trying to insult you mr. Chucky, im just trying to answeryour question the best way i can. I dont intend to get into a big argument about this. Im no expert, im a noob and this int my thread. Heck it might kill the fn plants and luigi would want to fly to my house and pee on my head, but i doubt it.
