Problems with growing certain microgreens

Hey peeps--new more or less to permies, although I've been a lurker for many, many years. Anyway, one thing I've had a lot of success is growing microgreens in jars and even in small batches in my Asphalt Rose grower, but I've been stumped trying to grow pea sprouts and to a certain degree, arugula, cilantro, and Italian Amaro Blend microgreens.

I tried pea microgreens in the little trays but with little success. I made the mistake (twice!) or trying to grow arugula sprouts in a jar and of course, that was a slimy mess. So, I switched to the trays and tried not to overwater, but the arugula is still not happy. I'm using either coco coir or jute as a mat. I hate to think I wasted money on the seeds. My seeds have been either from Todd's Seeds or Biological Interests. I've had luck with Broccoli and Friends and their Radish blend in the bottles. The ones that do best in my trays are Biological Interests Jazzy Mix and Sandwich Mix. Any thoughts?

Peas are my main winter microgreen. I've found that the biggest thing for them was to use at least a thin layer of inoculated potting soil. Just coir was not a winner for me.
I did do up a post that shows how I grow them. Growing pea microgreens

I'm not familiar with the setup you mentioned but the lack of soil may be the issue with peas.

Funny to see your post today about microgreens. I just watched a video 2 days ago about broccoli microgreens being one of 3 key foods to add to a Mediterranean diet to really burn visceral fat rapidly. The other two were walnuts and salmon. Good luck with your growing!

Thanks for that. I may have to think about using soil for peas. Hydroponics tends to be good for  a lot of things, but apparently not peas. Hmmm...

Peas definitely want soil, even a thin layer makes a big difference. Arugula in a jar is tricky too, the seeds go slimy when wet and don't do well without something to grip onto. I've had better luck with arugula in a tray than trying to sprout it.

I do a lot of sprouts so I don't understand trying to grow microgreens like I do sprouts in a jar.

As described, I just see the sprouts going slimy before getting the leaves for microgreens.

Generally, the finicky microgreens I do in trays, but I still have issues. The "easy" microgreens can be done in jars. Arugula, definitely not, but I'm having issues even in the trays.

I do all microgreen growing in jars and each type takes a little bit of a learning curve.  For instance peas take around 10 to 14 days to be ready, but I couldn't get peas to grow more than 10 or 11 days because they would get stinky if I left them in to grow longer before harvesting.  It seems like others are more forgiving re. stink as long as I check on them and make sure they don't get too stuck together.  All microgreen growing in jars so far has involved a bit of tending to them, I can't just set it and water it without manipulating them with my hands to keep them from getting stuck and slimey.  But peas can go off really fast like one day they're doing well and the next day they're nasty.
