Thanks for dropping this in here!
I really like pubmed’s “related articles” lol
Here’s a brilliant new Canadian paper that is the most comprehensive thing I’ve ever seen on botrytis cinerea and cannabis, it’s going to take a while for me to digest this:
To evaluate the hypothesis we examined the impact of five supply ratios of NH4/NO3 (0, 10, 30, 50, and 100% N-NH4 +, under a uniform level of 200 mg L-1 N) on plant response.
Shit!
These guys picked some pretty extreme ranges to test. I’d rather see the ratios from like 0-2… not many people using a 10x ratio due to calcium requirements, which come from calcium nitrate for the average person. I guess they’re probably concerned with field growing rather than inert media where all the calcium needs to be supplied by the nutrient solution.
But yeah NH4 is a bit rough due to being a much smaller molecule with much faster uptake rates compared to NO3. It’s much harder to control, but could have some beneficial properties in small amounts with regard to counteracting pH rise.
