I water similarly to the way Bill does. I fill to top of pot while water is meanwhile running out reservoir holes, straight RO. Mid-week I use RO plus fertilizer and whatever (Kelpmax once a month, biological couple times a month) and fill pots one to two or so inches above reservoir only and excess running out.
It saves money on the additions to the RO, plus still gets the job done. Economically, for me, it works well, and the plants don't appear to care. I used to completely flush twice a week, but started doing it this way about six or more years ago, and haven't noticed a difference other than in my wallet.

Here we go again.
In my opinion Miss Orchid Girl has developed a presence on YouTube, makes money at it, and markets herself very well. She gives some good advice and some poor advice, in my opinion. Her way of growing, and her opinions, are just that... opinions.
It's up to each individual to take another's opinions and utilize them or not. Whether one speaks well or makes an entertaining video is a different subject and in the eye of the beholder. "Good" or "bad" advice is subjective to the individual grower.
Overall, let's not get sidetracked by yet another Miss Orchid Girl conversation here. That's a conversation best left to already existing threads, or a different thread which would belong in Orchid Lounge.
