I sometimes use an old miracle grow sprayer for general garden but I was told that the superthrive comes out very quickly. Most people I know use a siphon that attaches between your hose and the turn on. The siphon tube goes into a bucket of solution. I prefer filling a couple of 33 gallon trash barrels, letting them set over night, and then using a pint of fertilizer (equals 1 tblsp per gallon), a shot of superthrive and about a third pint of seaweed extract. I fill two large watering cans at a time and sing the music from fantasia where Mickey hauls the water as I go from pot to pot. It amuses my wife. Bill

Bill,
Love to see you sing like Mickey Mouse! Go Mickey! Too funny! Jennifer

I like this one, it's easy to used. All you need is a 5 gallon bucket and a watering wand.

Thanks. I'll look around for something like that. Considering the high prices I found for adjustable ratios
I can adjust the rate if this siphon pulls at 1 to 16 by changing the concentrate ratio.

I use a 33 gallon trash can filled with water plus fertilizer/supplements and lower a sump pump into the bottom of the can. A hose attached to the sump pump will pretty much water/feed all my plants. I'm too lazy to haul watering cans to each plant. works for me.
