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!

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 |

one way of finding out where to buy it
1. Go to http://www.physan.com/ 2. Choose "How to purchase" from left side menu 3. A "STATE-BY-STATE" listing of suppliers shows up 4. If you click Alaska, the resulting distributors are not in Alaska, but will ship there 5. Select one that is not marked as Wholesale Only other (and probably cheaper) options include: http://www.lsorchids.com/store/cart....FTtLGgodiSR_PQ http://www.amazon.com/gp/search/ref=...eywords=physan http://www.77hydrostore.com/77hydro-...ysan208oz.html http://www.gardeningsupplywarehouse....products_id=50 When comparing prices, be sure to consider different shipping and handling costs.
