Aspirin Spray

[iceicebaby]

Hi friends, can't we compile all this informations about dosage and supposed action and make a small article and post it on the board. So in future it can act as source of information for others. Or does such an article exists of which I am not aware of?

I'm agree with DEV.... but we need some results in orchids in a seriuos investigation... I can't expose my CHIDS to a aspirin overdosis...

Alright, lets have a trial for those that can be bothered to do it, take some orchids of the same genera say Masdevallias or Odonts or anything else and spray half with your normal feed and the other half with an asprin added to your spray and see what the results are in the next 3 months.

OK.... I can do this experiment.... I can try with some maxillarias....

Because plants of the same species can still vary in their vigor, if you want to do such a comparison and have it be even minimally valid, you'll need to do a whole bunch of plants - a few dozen per side at a bare minimum.

You are right RAY... if we need a scientific experiment with credible results we need a signicative number of plants.... in the same conditions and in the same size... maybe a nursery... they can do this experiment with a group with this characteristics...

A mole of acetylsalicylic acid is 180.16g, a mole of water is 18.01 grams. Therefore, you need to dissolve 15/1000 x 180.16 = 2.7 grams of acetylsalicylic acid in 18.01 grams of water to make that concentration.

As a typical aspiring is 500 mg (1/2 gram), and a quart of water is roughly 950 g, you would need to dissolve 285 aspirin in a quart of water to achieve that concentration.

I ain't puttin' that on MY plants!

"dissolve 285 aspirin in a quart of water" ???. It's nonsense!!!! I agree that we ain't puttin' that on our plants! but NOT agree with the calculation!!!! In scientific concentration definition, 15 millimole concentration means 15 millimole in a LITTER of water NOT in a mole of water!!!. So using 1.5 tablets of Aspirin (81 mg) in 2 gallons of water (in the article) made sense. That is the way we used to put few aspirin tables in flower pots to keep cutting flower fresh longer.

I though there was something wrong with the calculation! Your answer seems much more reasonable. I never was any good at calculating this sort of stuff, in gives me a head ache. So how did you calculate the 81mg for 2 gallons?

15 mmol/l=.015mol/l=2.7 g/l
If its a 500 mg pill, that would be 5.4 tablets per liter, which would be about 20 tablets per gallon. That's not 285, but it's also not 1.5 tablets in 2 gallons
