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
