TL;DR: both clusters are the same, but I will redo the test
Good morning, my fellow mushroom enthusiasts!
In my Original Post I examined the effects of additional nitrogen supplementation by using diesel exhaust fluid (urea) for growing mushrooms.
As written there, I had to update the post just a few hours after publishing it, since the buckets already formed pins after just 16 days!
Now, a few days later, I got my first harvest. 800 grams total, but (sadly) both buckets (sample and reference) looked the exact same. Even the mass was, almost by gram, the same.
What now?
At first, wait for further flushes. Maybe, the urea bucket will provide more than the reference.
Also, I will redo the test. This time, with WAY more urea. I’ve read somewhere, that many growers aim to have 1% nitrogen in their substrate by using husks.
In my case, this means 45 g AdBlue (15 g urea) per bucket. Also, I’ll use less grain spawn next time for not altering the results.
… So, I’ve got some work to do! :D
Are you going to eat mushrooms that you’ve fertilized with Ad-Blu? Just wondering not passing judgement
Already did :D
I also eat veggies where the soil has been fertilized. And urea is one of the most used fertilizers for plants. And even if I ingested something, it’s pretty much harmless.
It’s not the urea I was thinking about, is there any other shit in the ad blue like antifreeze or anything?
AdBlue is normed. It only contains a very specific amount of urea (32,5% to be precise) and destilled water, nothing else.
Still, I’m glad you asked. Safety is always priority number one! :)
