Sowed my onion seeds under lights 1/10. I got maybe 60% germination at best, and about a third of those seem to “runt out” - I start to emerge, but instead of sending out that first long see you leave, they kind of just get about an inch tall, then the tip dries up, and most of the time, those don’t ever really recover.
Any idea what causes that? The only thing I can think of is that the air is too dry.
The ones that did make it past that stage look great, but instead of the 80 plants I was hoping for, I only have about 40 from the original sowing.
I sowed a second round since I had seed left. So I’ll end up with the right number of plants, although about half of them will be somewhat behind the other set the time I transplant them.
I used freshly purchased seed packed for 2019.
