Tyria F1 Hybrid Cucumber Seeds

I've been gardening and starting plants from seeds for 30+ years and feel quite comfortable with knowing what to do. I've tried 3 different methods to get these seeds to germinate and the results are a big fat zero. At least 20 or so Tyria F1 Hybrid Cucumber Seeds used and not one single one has germinated.Can I rate this a zero or do I have to at least chose one star?

I’ve been growing cucumbers in my garden for years. I was looking forward to trying a new variety but ended up wasting money. This is the first time I’ve bought cucumber seeds and not had a single one germinate. I used a jiffy seed starter tray with the larger peat pods for vegetable plants and only these failed to sprout. If you’re looking for a seedless cucumber, try Sweet Success instead. As long as they’re kept away from other varieties that might cross-pollinate with them they’ve been seedless and delicious and I had a 100% germination rate with those unlike these Tyria seeds.

The seeds did not germinate except only one seed. The plant gave only 2 cucumbers. I wanted to get money back but address was damaged, nowhere to write. I think that they sent very old seeds
