Coffee - Pros/Cons

I'm preparing for my first monotub, and I'm not sure if I should use coffee in my substrate. I've been told that coffee increases your chances for contaminants...
Please enlighten me. What are the advantages and disadvantages of using coffee in your substrate (I'm using coir, verm, and gypsum already)?

coffee grounds get moldy pretty easily ..
maybe substitute worm castings or a little chicken manure.

Adds extra nitrogen I believe.
I just started a new grow with coir and espresso grounds. I've never had trouble using coffee in the past. I made a thread about this last night or night before, and this is what RR said about the pH level-

I've never really had problems using coffee. RR and others have done grows where they grow just off bricks of used coffee grounds.

I've only done around 30 jars so far but only 2 out of those got contaminated. They happened to be 2 out of the 3 that I used coffee ground in. That makes me scared to add it to anything bulk. Mold loves coffee. All you gotta do is leave some in a cup overnight and your likely to find shit growing in it already. Trying pure coffee sounds cool though. Wouldn't be much of a loss if it didn't work.

You used coffee in jars that you knocked up, is that what you're saying?

I would suggest skipping the coffee. It sounds like it will be one more new thing for you to tangle with. Perhaps you could get accustomed to simple tubs before going with the optional stuff. Could be less to worry about in the long run if you need to trouble shoot your first few attempts.

About 20 percent coffee grounds 80 percent wbs. Green mold got 2 of em. The third jar that made it is actually the only one I haven't done something with yet.

you used the coffee wrong. don't mix it with your grains. when hydrating your grains you can use deluded coffee in your water. coffee grains are for the bulk substrate, not for the spawn. that's why it went bad. you need to past. the coffee, you sterilized it. big difference. check the link in my sig, there is a ton of info over coffee in it.

Some of the first threads I Seen people using it in were using jars so I did it a day or two later. I just checked that jar because of this thread and ended up having to break it because it was pinning on the sides.

Put coir in bucket. Boil water Pour boiling water in bucket Let sit for 30 minutes. Stir, cover, let cool overnight
You want to pasturize at 140-160f

That is not pasteurization and will lead to a high incidence of contamination. You should NEVER pour boiling water on anything you're trying to pasteurize. If the substrate exceeds 180F the chance of contamination is higher. You should hydrate the coir and then slowly bring the temperature up to 140F and try to keep it there for one full hour. Don't let it go above 160F. RR

I totally respect your knowledge and take everything you say as the truth. However, I've found that adding ~200f water to a bucket with nothing but coir in it drops the temp to ~150.
I am well aware that it is bad to go over 160, which is why I included the temps for the new grower. Most people do not have a kitchen thermometer to even check so I still feel its safe to do it the way ive suggested because the temp should not be higher than 160, ever, even with adding boiling water.
edit: if you still feel the initial pouring of the boiling water has a negative impact I will not suggest this method again. Ive had little contam problems but if it is incorrect I will stop teaching it. I just was trying to help out. I know when I got into coir a few months ago there wasnt a clear, clean cut easy method. Ive had 100% success with all my coir prepared this way. And it is very easy to do.

youll be fine, im telling you. Ive prepared over 10 bricks of coir that way and have not had a single contam. If you read Damion5050's tek he does the same thing (STEP 5 "Pour the boiling water into the 5 gallon bucket over the coir/verm mix.") thats coming from a trusted cultivator who has probably done coir a million times. No disrespect to RR as he is the mycology god in my eyes but your coir will be fine.
