@Tinytuttle, I'll try to get some under my microscope. The photos above are from my Canon EOS T5 using 10x macro lens, The largest photos also had a 30mm macro extension tube for approximately a total of 20x.
I did look up aphids online and this picture looks like them, or would with more magnification.
This is the largest photo I was able to manage with the Canon. It reaches a point where the lens on the Canon blocks any light making it impossible to take a larger image than this one.
@NoobyMacDooby I normally grow seeds in coco. I tried to grow some difficult seeds last year and had no luck at all. I read postings from people that got those seeds to grow. The one thing they had in common is planting in soil. I expected this to be a difficult seed, so I planted it in soil (the first time in more than 2 years). I purchased Happy Frog because it has good reviews.
@ReikoX, ok, now I absolutely need to put them under my scope. Here are pictures of some bulb mites (the name comes from their proclivity to eating bulbs).
They also could be soil mites (same as bulb mites?).
I actually thought Happy Frog was sterilized, but looking at the label, I can't find it, now. I may have just assumed that a soil that expensive was pasteurized.
I'll see if I can get a mite or 2 in a dish slide. If successful, I'll post a photo.
Thanks for all the responses!
