Cheapest solution...
Just break up some aspirin and dissolve it in water. About 1 aspirin per 2 gallons of water and spray that after about 30 seconds of aerating (shaking the container) of crushed aspirin in the water!
There is an old trick to keep cuttings of ROSES alive longer, is to break up some aspirin in the water (very little - or at the above equivalence).
What it does is that it supplies the hormone which a plant would use food from its leaves to create. Kind of like a drug for plants. I have only heard that there is a similar effect caused by cigarette smoke - certain toxins (to us) can be useful for plants .... However, unfortunately the toxins involved in this beneficial process have not been isolated and I can only imagine that not all fumes from a cigarette are not healthy for plants.
Back to aspirin water!
Hey, have you ever heard of a JOHN ELLIS water machine? Formerly known as a Water Wizard in the early 90's... This water machine uses water plasma streams (or so it appears!) to purify water in the most efficient process known to man. The only machine that can ACTUALLY 'purify' water.
OK OK... I'm done...
P.S. Don't listen to 'professionals' who just say something CAN'T and DOES NOT work because they never learned about it in college!
