Nope, haven't tried one yet. This "market survey" is the step before that...

From the literature I got from the manufacturer, it looks like a simple device - poly tank to which
you add fertilizer and water to form your concentrate, screw on the lid, which has an adjustment
dial and the inlet- and outlet hoses which connect to the coupling device on the spigot, and away
you go.

leaks!!!
Oh yes, have you tried one out? Also as long as it is not a mathematical
challenge?

Question for the gang:

We've often discussed and debated the utility of fertilizer
proportioners ranging from hose-end types to siphons to
Dosatrons/Dose-matics.

I have an opportunity to begin carrying a tank-type device that
connects to your hose bib, and that feeds at a constant rate no
matter what the flow or back pressure. Price is likely to be less
than $100 for a unit capable of feeding at an adjustable 1000:1 to
100:1 and holding several gallons of concentrate.

Do you think there would be a value in them? I feel quite certain
that if they had been available before I bought my dosing pumps, I'd
have gone with these instead - heck, I mix 5 gallons of fertilizer
concentrate for a 100:1 pump now, you think I'd mind doing so 40%
more often to save $300????

Thanks for your input.
