Sounds like PH has a lot to do with good germination and growth. It is something I had not considered. But I am a bit confused as to proper PH level given previous posts....
They said micro greens like a PH of 5.5 and wheat grass sprouts are micro greens so why not.
At this point, I thought your target PH level was 5.5.
I tested my water and it's PH is 7.5, so I used 3cc of their PH Down in my almost gallon container to get the PH down to 5.5 or so.
Again, PH 5.5 seems to be the target.
I almost never see any mold maybe a couple of small batches since I started to acidify the water down to 5.5 PH.
Still looking like PH 5.5 is your goal.
Interesting turn of events here, spring rains started and it changed the chemistry of the ground water (I'm on well water). Whole trays started having poor germination and slow growth, so bad I was tossing out trays. I reduced the PH Down from 3cc to 1cc per gallon of h2O and like magic the sprouts took off again and started growing nice thick green healthy sprouts for the hens.
Here is where I started to get confused, because you seem to indicate that your well water PH level has gone down, and you no longer have to add as much chemicals to get that PH 5.5 target.
The desired PH is 6.5, when the well water PH went down then I was down to 5.5 and got very bad germination and growth.
Your latest post indicates your desired PH is 6.5, which seems to be different than your previous posts that I thought your goal was PH 5.5.
I know that a PH of 7.0 is considered neutral, and I would naturally think that big any change from PH 7.0 might start to have negative effects on germination and growth.
I don't mean to beat a dead horse, but I am still not following what your target PH level is and how the PH level is affecting your fodder germination and growth. I think this is worth clearing up because I would like to know what PH level has worked best for you as you indicate PH level is a big factor in better fodder germination and growth.
@jthornton , Love all your posts and updates on fodder growth. Hope you don't mind my lack of understanding and questions on a subject that I am very interested in understanding better.
