Buy the leisure split cilantro seed. Kitazawa is the best source. Soak for 12 hours then drain & germinate in a jar or tub until you see the root poke out. Cover with 1/4” of medium when planting and stack the trays with weight on top until the seedlings start to lift the trays above. Unstack & cover with a flipped over 1” 1020 to black out until they lift the blackout tray. Put under light. This should eliminate about 95% of the seed hulls. Use this exact same process for beets or any other stubborn micro that likes to hang onto the hulls.

First time grower. Stacked for 8 days. These guys don’t seem to be going anywhere and if I try to pull them off they take the tips of the leaves with them.

Crack them. I got good results putting my seeds in a ziplock bag and crushing with a rolling pin. They crack, break. I thought I had killed them until I got the best germination I ever received plust no/ limited seed hulls

Those and Detroit red beet I had a really hard time with the hulls, adds a lot of time to harvest Putting 1/4 in a soil on top of seed helps a little I noticed also cracking the cilantro seeds is important

Burying them about a half inch beneath the soil helps

best solution would be, to buy split seeds. But even with those, you can help, by having more weight during the blackout period, with going across them each day with your hands,...

Great advice, thanks everyone! Had a similar issue with Swiss chard, but not as bad.
