Our verdict

The ML50 is DIG’s kit for planter boxes and short vegetable rows, and the best fit among our picks for a raised bed. Instead of loose drippers it uses 50 ft of 1/4 in dripline with 66 emitters built in every 9 in. They are pressure-compensating, rated at about 0.52 gph at 15 psi and 0.65 gph at 25 psi, so the far end of a row gets close to what the near end gets. A backflow preventer, a regulator preset to 25 psi and 50 ft of 1/2 in poly tubing complete the faucet side, and DIG gives the same three-year limited warranty as on its bigger DIG GE200.

DIG rates it for up to 150 sq ft, and the whole kit uses only about 36 gph against DIG’s 220 gph maximum; DIG says up to five kits, or extra 1/2 in tubing, take it past 700 sq ft. The drawbacks are no timer, only a 60-mesh screen and few places to buy it: the one US retailer we could read listed it as out of stock when last checked, and we found no Canadian seller. It is our raised-bed pick in the best drip irrigation kits; compare it in the drip kit comparison.

Laying out beds and rows

Fit the backflow preventer to the faucet, then the regulator, then the swivel adapter on the poly tubing. For planter boxes, tee off the 1/2 in line, run tubing up into each box and turn it along the rows with an elbow; for rows in the ground, lay the 1/2 in line across the rows and a foot past the last one. Lay dripline beside each row, or between two narrow rows 6 to 10 in apart, and pin it with the stakes. DIG’s instructions describe up to ten rows about 5 ft long, while its product page talks of five lines up to 10 ft; either way, no single run of this dripline should pass 28 ft.

Keep emitters off plant stems, which can rot. In a new bed, DIG suggests watering first for 45 minutes or more and planting in the middle of each wet patch, about 2 in from the dripper. Its starting schedule is 45 minutes to an hour every two to three days, more often on light soil and less on heavy clay.

Filter, timer and care

Flush the lines before first use with every end open, then close the poly with a figure 8 end and the dripline with a goof plug. Leave the end of the poly line on the surface, even under mulch, so you can flush it again later. There is no timer: DIG suggests its B09D or B092A battery timers or its EVO 100 solar timer, fitted after the backflow device. The kit’s backflow preventer protects the faucet, but local rules vary, so check with your water utility (our backflow preventer guide explains the devices). DIG’s documents give no winter advice; our winterizing guide covers drip kits. We found no owner reviews of the ML50 we could read.

DIG ML50 questions

How much bed can one DIG ML50 water?

Up to 150 sq ft, by DIG’s rating. DIG’s instructions describe up to ten dripline rows of about 5 ft, and its product page five lines up to 10 ft, with no single run past 28 ft. To cover more, join up to five kits or add 1/2 in tubing; DIG says that takes it past 700 sq ft from one faucet.

Is the ML50 dripline pressure compensating?

Yes. DIG rates the 66 built-in emitters at about 0.52 gph at 15 psi and 0.65 gph at 25 psi, so output changes little along a row. The kit’s regulator holds the line near 25 psi, DIG’s recommended operating pressure, even when the faucet gives as much as 100 psi, the most DIG allows coming in.

Does the ML50 need a finer filter?

It is worth adding. The kit has only a 60-mesh screen in its swivel adapter, and DIG recommends its 155-mesh filter, model D57A, where water quality is poor. Colorado State University Extension suggests 150 to 200 mesh for drip even on city water, a range the D57A falls in.
