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!

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!

Welcome back! US gallons, of course! Are there any other gallons? grin ;-) -- Thanks for the welcome. I note your absence from postings for a week or so. Did you go away for your Spring break? 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%.

well you won't kill them, if it works it works and if not, hope you got
some physan (ps anybody know where I can get some shipped to alaska) If it does work let us know. Jack |
