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.

If it would work at the end of a 100 ft hose fed from my house, then I would
buy one (not for my orchids, but for outdoor beds). I have tried siphon
feeders, but they don't work when a 100 ft hose is attached since the
pressure drop is too large.
