I hate to rain on Diana's parade, but the EZ-FLo is probably to be avoided.

The EZ-Flo metering device works by diverting a small amount of water from
the main line (your hose) into a tank containing concentrated fertilizer.
Then that same volume of SATURATED solution gets injected back in the line,
so you get mixing in the hose. The dosing rate is controlled by the volume
of the diverted water/solution.

The problem is that the device was designed for use with (their own brand
of) powdered fertilizer, and once all of the powder has dissolved, the
liquid in the tank is no longer saturated, so the mix ratio coming out of
the end of the hose gets more-and-more dilute. If you use a liquid
fertilizer in it, which by definition is at- or below saturation to start
with, that changing mix ratio occurs right from the start.

My guess as to Diana's and Frank's success with it is that if probably
relates to the vandas getting more overall nutrition, due to the ease of
use.

I'm getting kind of tired of filling and refilling my 1 gallon jug with
fertilizer solution, but I remember reading some reservations about
hose-end
mixers. I fertilize 1/2 strength every other week and flush with water
the
other times, which seems to work for the roughly 75 plants in my little
GH.
Any suggestions?

Hi, Tom,

Frank put in a watering system earlier this year, especially for the
Vandas.
Since they grow around the pool, he didn't want the fertilizer to go
through
that system (the spray inevitably hits the pool). We also have a wand
hooked up to the water source.

We bought an E-Z Flow in-line bottle (very inexpensive) from Morton
Products
on line. Now, he fertilizes the Vandas using the wand, with the E-Z Flow
turned on. Piece of cake. I don't have the URL off hand, but it's easy
to
find.

We haven't measured the output as some no doubt have, but I can tell you
that the Vandas are in pig's heaven, and are blooming more frequently than
ever before, so I can assume they are getting what they need. In the main
grow area we still water with a hose, even though the watering apparatus
is
out there. So, there we use an ordinary hose end bottle. Results are
good,
and everyone is happy.

HTH
