What's the consensus on cow manure?

I've seen a few posts on here about it, one guy said it made the soil to rich and he decided to stay away from it.

I have virtually insane amounts available to me so I'm wondering what experience you guys have with it? Is it worth it?

worth what? what do you want to do with it? for growing cannabis outdoors?? I use bullsfeces in my outdoor mixes, if its all you have available compost a large batch of it and when it cools down amend your native soil with it and I bet youll get some nice trees.

I agree, people have been rotating cattle and crop lands out from time to time forever. Crops grow and are harvested, livestock come in and feed on the grass/leftovers and leave droppings, earth is replenished and can be used again the following season to grow a new crop.

Obviously its more intricate than that, but you get the idea ;) experiment!

Needs to be composted. Then you can use it both indoors and out. I mix composted cow, chicken and horse manure + local compost + peatmoss + vermiculite + perlite + granite dust + silica sand to make my "best soil on earth" DIY mix. I have two autoflowers growing in it and loving it now. That said, I mostly save that stuff for outside, I'm sick of bringing insect eggs in with soil. I'm going hydro for everything now.

Before composting it will cause PH swings and nutrient burn from excessive N.

If it's composted it wont stink or it will have very little smell. if its not composted you need to add lime.

I was about to say no way until I saw Dr. Peckers pics. That will change your mind. I like the looks of that top pic. What is that? I still think it should be well composted, and small amounts if I were going to use it.

Fox Farm"s Big Bloom has Bat shit in it and it works very well without smelling. If you have cow shit available I'm assuming you have a barn in which case you probably have bats if you are trying to save money why not collect their shit. Just kidding,. do what works for you.

What is the point in doing that? I would think the result would be losing a bunch of N in the reaction due to off gassing and very high levels of calcium in the resulting mix. I know you for sure don't want to repeat that process multiple times on the same soil.

that's a beautiful grow

how much cow manure per soil is a good combination to get these kinds of results?
3 parts cow manure 1 part perlite 1 part promix or just enough to lighten it up. I know people that grow in just cow manure and their plants look just fine you cant really overdo it.

If its composted you dont want to add lime. Some of my friends grow in green cow manure but they always add lime.
