We're setting up a drip system for our 3 acre market garden. Wondering what the standard is these days for watering in direct seeded veggies when using drip as the main source of irrigation. I was considering setting up a Wobbler setup (by senniger) on aluminum 2 inch pipe that could be moved around to the sections that are direct seeded and once established run on drip until harvest.

Any input?

Also, we will be drawing from a pond 75 feet above the growing space (plenty of pressure) but would like to filter out weed seeds. Is a disc filter the best way to go to accomplish this or is the $ better spent on a sand filter?

Thanks.
