Need Pump for Feeding Potted Plants

starting bigger than ever grow.
using 5 gal buckets
lookin for a good set up for wattering this many plants. ( prob. about 30 gal each time)
lookin for a pump with hose and metering wand.
has anyone used any kind of setup like this?

I've been using a small fountain pump, connected to a 1/2" poly hose that can be stretched to accept a garden hose female connector. Then I use a garden shut off valve on a watering wand.



You can use a larger pump if you want, find one that sucks from the bottom if you want to empty your watering rez. I like the low flow to slowly saturate, but then again I'm only dealing with 4 plants.

Thanx a bunches
