Which Paphiopedilum to move to semi hydo

[Gigi]

first time poster so please be kind. I have a few paphs that have not put out any new growth for years and I was wondering about trying semi-hydo to see if they would improve. They are (Supersuk x sukhakulli) Jaguar x Double Deception and Hsinying Magic #1 x Callosum Nice and Tall. They are currently growing in Orchidia. The leaves and roots appear to be healthy. I believe I have them in the appropriate light/temp/humidity.

I have a sequential bloomer Sunny Delight in the same mix and location that puts out new growth and blooms every year. It is larger than the others.

Any assistance would be greatly appreciated.
