Ok, so I'm lazy tonight...
....and it's late. If I want to soak my orchids in Physan 20 solution and
need 2 tsp. of 20% Physan per gallon of water,how many tsp. do I need of 50% Physan for 5 liters? (I can get 50% benzalkonium chloride here which should be relatively similar, if not equal, to Physan - http://en.wikipedia.org/wiki/Benzalkonium_chloride) -- -- Reka This is LIFE! It's not a rehearsal. Don't miss it! http://www.rolbox.it/hukari/index.html |

Forgive me for being picky, but were those US or imperial gallons?

I use benzalkonium chloride at work (disinfecting handwash gel, the
alternitive to alcohol) there are different parts of the mix of compounds in physan that work on different organisms, what I mean is that it should work, but maybe better for bacteria than algea ( will a mircobiologist or organic chemist jump in here If you read the techinical data it should explain the mechinism of action, which should go into what it is approved for use on and what it has been tested on.... I do know that it will make pennies very shinny but then prone to corrosion later. Jack |

1) Use 2/5 of the amount of 50% to equal the 20% stuff.
2) 3.8 liters per gallon is good enough. 3) One teaspoon is about 5 ml Therefore, if 1 teaspoon of 20% per gallon is your target, then you use 2 ml / 3.8 l = about 1/2 ml/liter of the 50% stuff. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Artwork, Books and Lots of Free Info!

A few pilots have found, to their sad cost, that US gallons are smaller than imperial ones. I guess that just goes to show one should read the manual *very* carefully.

Reka, I use a little less than a teaspoon in the 1 quart spray bottle. I
have never dipped & soaked the entire plant. I have a couple of plants that I am going to experiment on. I browsed through this webpage & noticed that just for the different types of orchids they call for different measures? Quite an in depth site. http://www.physan.com/index.html -- Cheers Wendy Remove PETERPAN for email reply Reka wrote: In article , says... ~1) Use 2/5 of the amount of 50% to equal the 20% stuff. ~ ~2) 3.8 liters per gallon is good enough. ~ ~3) One teaspoon is about 5 ml ~ ~Therefore, if 1 teaspoon of 20% per gallon is your target, then you use 2 ml ~/ 3.8 l = about 1/2 ml/liter of the 50% stuff. ~ ~ Okay, so we are talking about 2tsp./gallon 20%, 1 tsp./5 liters 50%.
