I've thought about that as well. My BIL works the pro desk at Lowe's, so I can get a little break on the hardware. I have about 18 vines now, and I'm hoping to sprout about that many more this year. The seeds are from some vines that are 75 years old. The man assured me they were seedlings, so the sprouts would be the same as the grapes they came from. Time will tell.
My overall plan is to run the water line between two rows of vines, with faucets going off in each direction. I had a lot of soaker hoses with leaks, so I cut them in 4 foot lengths to use with the grape vines. I was going to just turn them on a trickle and leave it unless we got lots of rain. With my sandy soil, it is hard to get too much water.
