Does it piss you off when you see so many untruths being peddled around online regarding light requirements for orchids? I can't count how many websites I see tell beginner orchid growers to place their Cattleyas/Vandas/Dendrobiums etc. in an Eastern window, or better yet, and Eastern or Southeastern window BEHIND a curtain or some other such obstruction. Where do these "experts" live? The sun? Pretty soon they'll be telling people stick their Renantheras in the refrigerator. I've had Phals that have refused to bloom in a straight Southern window, never mind Cattleyas, and I live in Texas (what I believe to be the hottest, brightest place on earth). There seems to be a lot of misinformation online regarding how demanding these plants truly are with their lighting needs. Put a Vanda in an Eastern window and watch it laugh at you...and then die.
