I sent samples for testing to rimrockanalytical.com. Use code "bulk10" for 10pct discount on orders of over 10 samples. Use code "be positive" for free shipping.I'm at the same latitude as you. How are you determining the gender of your plants?
It worked out to cost about $12 per sample. It was worth it for me to cull through sprouts faster, saving time and space.
Now, the plants in the ground are already showing some pistil preflowers at nodes.
