Questions about orchid care.

[magicsomething]

Hello! I've been researching to keep my orchids healthy (Phalaenopsis, Encyclia and Brassavola, unsure of the excact species).
And I find a lot of information that just make me want more information, as everyone seem to be doing different things on the same plant species.

On the next information I find online.
Truth or False?

Avoid letting water get in the center of the leaves in Phalaenopsis.

Water all days a little.

Water only when dry and a lot.

Clean all orchid leaves.

Let Brassavola dry between watering.

Remove death material, leaves and roots.
(How I remove roots and how I know which roots are dead? People on the videos I see seem to remove anything that doesn't look fresh, but my orchids have 1 or 2 pretty roots and the rest are brown)

Fertilize once a week except while "sleeping" or blooming.

Use fertilizer at half the strenght.

Urea free fertilizer for Phalaenopsis.

Natural fertilizer attracts cockroaches.
(Made from banana peel, potato and cinamon)

Natural fertilizer is not really effective.
(This was very frustrating to read)

Tea bags content is good for orchids that need Nitrogen.
(All need Nitrogen right? And which tea bags? I drink tea at times but, wouldn't know which ones to use, I suppose any from Camelia Sinensis? Black/Green/White)

Low intensity growing lights.
(Carnivorous plants loved intense light but I get they are very different)

The heat from the lamps, hurt the orchids.
(I've grow corals (I know they are not plants) and other plants under flourecent lights before, I never keep a certain distance of the plants from the lights, using fluorecent bulbs, pl or t5, some plants even grow so much that they touched the light bulb)

Orchids don't like "long days"
(I turn on the lamps when I wake up and turn them off when I get to bed, that can be around 17 hours of light, is okay?)

I know all species are different, so if any of this information apply to an specific species, I'd love to know.
I grow my Phalenopsis on a window, but the rest on my room with lamps.
Thank you kindly and sorry for all the questions.
