My dad’s first blooms

Over the past few years I’ve been picking up salvage orchids at Lowe’s - mostly for $1 - and taken about half to my dad. They were all doing ok but not blooming when mr lg9 moved ours into a south facing window and now - wow (see extra). So we moved my dad’s and 2 weeks ago his first stared blooming- it’s very exciting since we had no idea we could do it.
