Why don't I just grow my autoflowers with just rabbit poop?

[Tom Bombadil]

Bunny poop isn't going to have everything the plants need all on it's own. Just like you wouldn't be healthy if you ate just one type of food all the time.

Rabbit Manure: 2.4/1.4/0.6 so pretty decent but later in flowering something higher in K, P and lower in N would be good to supplement with.

No idea what micronutrients might be in it but not all I'm sure.

My cousin grows massive plants with only rabbit poop and no additives. If the nitrogen thats in the poop isnt hot and the poop doesnt need to be composted prior to use, then good amounts of N in the poop wont have any adverse effects whatsoever? The plant will simply take what it needs. I use TLO soil and always have good amounts of N in my soil and I still get a nice fade with a finished plant? Go figure. I bet you wouldnt want to use it indoors unless its composted though lol.. Probably smells like natures living soil! haha
