Drip Tape

Drip tape is the standard way to put water at a fixed spacing along a row: field beds, greenhouse ground beds, and lines of containers set under the tape. It is a thin-wall product with a narrow pressure window, sold by diameter, wall thickness, emitter spacing and flow per emitter.

The decision that matters most is whether your run length and grade let a standard non-PC tape stay inside that window from the first emitter to the last. Short, flat runs open up the whole page. Long laterals, slopes or a supply that wanders push you toward pressure-compensating tape or a shorter layout on a larger diameter. Settle that first, then choose wall, spacing and flow.

Which tape for a field bed, a greenhouse bed or a line of pots?

Start with what sits under the tape.

Seasonal row and bed crops on flat ground are the home territory of standard non-PC tape, and every manufacturer on this page covers it: Netafim Streamline X and Typhoon Plus, Toro Aqua-Traxx, Rivulis T-Tape, Jain Chapin Drip Tape and IrritecTape. Walls of 5 to 8 mil are the single-season choice. If you will retrieve and reuse the tape, or bury it, move to 10 to 15 mil. Netafim Streamline X EZ is a recycled-content wall for single-season vegetables with shallow burial to 2 inches.

Containers in rows are the nursery case. Netafim Space-It is made for it: each dripper is visibly marked on the tubing so pots line up under it, spacings run 12 to 24 inches, and flow is 0.2 or 0.4 gph per dripper at a 12 psi maximum. It only works where pots are uniform and stay put. A mixed block wants spray stakes instead.

High-density plantings such as plugs, cut flowers or tight greenhouse rows want close spacing so the wetted strip joins up. Irritec eXXtreme Tape goes down to 3 inches and Jain Chapin to 2 inches.

Long laterals, slopes or a variable supply call for pressure-compensating tape. Netafim DripNet PC Thinwall runs 6 to 36 psi and Toro Aqua-Traxx PC 4 to 25 psi, so the last emitter keeps pace with the first. Toro Aqua-Traxx FC is the flow-controlling option for undulating ground where you dial the rate.

What do the water and pressure need to be?

Tape runs at low pressure. Toro's standard Aqua-Traxx, Rivulis and Irritec publish flows at 8 psi, Netafim at 10 psi, and Jain rates Chapin at 8 and 10 psi. The maximum is set by the wall: thin 4 or 5 mil tape tops out at 8 to 13 psi depending on the line, while heavier Netafim Typhoon Plus and Aries Thinwall walls are rated up to 32 psi. Fit a pressure regulator matched to the tape at the head of every zone. Unregulated wells, pumps and municipal supplies run well above tape pressure and blow tape off the fittings.

Flushing pressure is higher than operating pressure; Netafim publishes both, so confirm your supply can reach it.

Filtration is not optional. Tape emitters are small labyrinths; a screen or disc filter ahead of them decides how long the pattern stays uniform. The tape spec sets the mesh: Netafim Aries Thinwall calls for 80 mesh, Toro Aqua-Traxx PC for 140 mesh. Clean well water can run on a screen; pond or surface water needs more, up to automatic self-cleaning units. Some emitters tolerate poor water better: Toro Aqua-Traxx Azul has multi-stage emitter filters, Rivulis Ro-Drip an expanding labyrinth, and Irritec eXXtreme is built for hard water.

Flow decides zoning. Emitter flow times emitters per 100 feet times lateral length gives zone demand to check against the pump or meter. Toro lists Aqua-Traxx (PBX) at roughly 0.09 to 2.96 gpm per 100 feet; spacing and flow move that number a long way.

What goes wrong, and how do the five manufacturers differ?

The failures we see repeat. Tape run past its pressure window, so the head of the bed floods and the tail starves. No regulator, or one set for dripline instead of tape. A filter that is present but never cleaned, or the wrong mesh for the emitter. Container tape laid with drippers between the pots instead of over them. Four-mil tape bought for one season and then expected to survive retrieval and a second year. And tape chosen on unit cost alone for a block where uniformity is what the crop is paying for.

The five manufacturers approach the same product differently. Netafim has the widest range on this page: Streamline X and Typhoon Plus for standard row work, Aries Thinwall for multi-season on flat ground, DripNet PC Thinwall when compensation is needed, and Space-It for containers. Toro builds everything around Aqua-Traxx, with Azul as the current generation, FC as the flow-controlling option and a PC version. Rivulis T-Tape has the widest flow range here, and Ro-Drip is aimed at growers new to drip or on very poor water. Jain's Chapin has been on American farms for decades and is the straightforward choice for seasonal rows. Irritec runs close spacings and is built for tough water, and their fittings make it easier to join products from several manufacturers on one block.
