Thats cool. I use the Delta Sprayer, a pressure sprayer. Have had it for 4 years, no problems. But it was 10 - 15 dollars.
I would probabaly go with a pressure sprayer too if I had mor orchids to water but as I only have about 30- 35 this workes well for me this year I did buy two and one is for plain water and one for fert.This year I have a couple that need rested in winter so being s/h ....I understand no fert counts as a rest in s/h so the plain water one will sit by them
