The proportioning system is really no different than a Miracle-Gro hose end sprayer or an Ortho Dial n Spray. Although, I suspect yours is more accurate. They suck a small amount to be mixed with the water going out the garden hose, too.
In fact the Dial n Spray is what I use for foliar application of Epsom salt. (One needs to do some extra calculating, since the Epsom salt is not a liquid, but it can be done.)
And since I am buddies with the Scotts/Ortho/Miracle-Gro rep at the store where I work, I have the old style of Miracle'Gro hose end applicator, too, so I can attach a hose (or whatever) on either end. My seedling lilies that are in pots are fiertilized with it.
mnorberry said:I purchased last year a kit but it really does not have any detail instructions on the amount or type of fertilizer to use.
Unless it tells you at what proportion the siphon is siphoning, that's not a good thing. How will you know how much of anything to put in? As far as what type of fertilizer to use, that will depend on your needs.
