More semi hydroponic questions

[Joshaeus]

Hi everyone! Long time no post (not that I was ever crazy active to begin with...) ANYHOW, I am interested in trying out some semi hydroponics for my house plants, but since I could not find a general forum for houseplants I came here; thus these will not strictly be orchid questions. Anyhow;

1 - Could semi hydroponics be used for succulents? If so, would there be any differences from growing typical plants in a semi hydroponics setup? (This also applies to epiphytic orchids...any changes?)

2 - For plants that require a dry, cool period to trigger blooming (such as Clivia and Dendrobium kingianum) could I simply put the plants in the fridge at night and put them back in their normal place come daybreak? Or would that be too disruptive for the plant? The difficulty of providing a non-freezing wintering period in a heated apartment has long steered me away from these kinds of plants...

3 - What are some recommended nutrient solutions for the plants? And how much should I dilute the mix indoors?

Thanks I tried reading the most recent posts on this subject, but the posters had different questions from mine.
