Adding nitrogen to substrate

#1722327 - 07/16/03 05:21 PM (19 years, 10 months ago)

For those who grow using straw as a substrate, is it possible to simply add urea or ammonium nitrate to the straw immediately before pasteurization? It seems like it would be a more convenient and simpler way of introducing nitrogen into the substrate than dealing with composting and manure. Anyone ever tried this?

I think the best way to add nutrients to any bulk substrate is with more colonized spawn. See my post in the "Spawn Ratios, which matters more" thread for a detailed reason why.

PM me with any cultivation questions.

I just looked at my profile and realized I had a website at one point in time on geocities, it's not there anymore and I have no idea what I had on it. Anybody remember my website from several years aga? PM if so please.

More nitrogen in a bulk substrate would make it more prone to contaminating. You want a relatively high C:N ratio (somewhere along the lines of 17:1.)

Composting, of course, is different, but I agree that it's a royal pain, unless you're planning on growing like hundreds of pounds or something. For all it's worth I've been more than pleased with yields on just straw. I'm pretty sure the ammonia produced in composting is just a byproduct of the actinos that grow. I'm not a big fan of poo, myself, but some people swear by it.

Micro, the way I understand it is that the amonia is produced during phase I composting which is not dominated by the actinos. Phase II is dominated by Actinos, and I believe they are responsible for digesting the amonia.

Regardless, I was always a big fan of straight straw and feel that a lot of the dung/poo/compost is hype over substance. Well, maybe not hype, that implies a motive. I think it's probably more of a trend, or fad, as would be expected from a growing population that is as networked as TOMC, as opposed to "real" cultivators who are much less communicative a more reclusive.

Poo rocks, but so does straw. It's just a little overshadowed at the moment.
