What dwarf tomato varieties would you recommend for a hydoponics set up?

That's the question: What dwarf tomato varieties would you recommend and who do you suggest I buy the seeds from? Yes, I am growing them in a hydroponics system. I prefer the tomato plant to be around 15 inches or shorter. Mini or regular tomatoes okay. Yellow or other colors preferred but red is okay.

I have been growing orange hat tomatoes, but I got the seeds from Amazon and apparently the germination is meh. I have one plant growing. Another is starting now that I've had to reseed it twice. 🤬 So if you recommend Orange Hat, can you recommend a better source?

Thanks.

Red Robin and Tiny Tim are the two I see recommended most for that sort of height, though both are red. Amazon seed does seem hit and miss for germination, I'd try a proper seed company instead and see if the reseeding stops.
