nenella, I grow indoors and every 2nd to 3rd weeks walk my chids to the sink and give them a good bath. Only once did I put them in a large cooler of water and fert, but felt uneasy and made a beeline to the sink to cleanse them. I have over 100 orchids and its getting to be a chore at this point, takes up to 6 hours to do this regimen, doesn't leave much time to soak the rays in the Fl sun, but you do it for the beauty of the prize bloom
I as well use the skewer trick but now they are on my watering schedule and doing very well. Orchids have a tendency to adapt to your enviroment so you will eventually be able to have them work for you instead of you working for them
Ross puts all his plants in a large bucket and has been doing this for quite some time from my understanding and he has not had a problem one...most do not recommend this type of watering. It works for him though.
