Space-It™ Dripline

Netafim USA’s Space-It Dripline is a drip system for watering potted plants. It’s a thinwall dripline with pre-spaced drippers designed to be placed directly over the top of pots with the location of each dripper visibly marked on the tubing. Positioning of the pots (plants) is quick and easy – just place the pot under the mark on the dripline – saving up to 20% in installation labor costs.

Each Dripper is Visibly Marked Saving Time During and After Installation

Workers don’t have to stoop or feel to find the dripper’s position in the tubing. The visible mark allows them to quickly and easily identify where each plant should be positioned. This also saves time after installation – there is no need to recheck the dripper’s position to make sure the water is dripping into the pot. Growers estimate that the time required to space out a potted crop can be reduced by 20% or more.

Reduces Crop Loss

Typically with unmarked tubing, some pots are out of position and do not get watered until positioning is corrected. Plant wilting is the usual indicator that a pot is out of position. With Space-It Dripline, you can simply look down a zone to see that the pots are properly positioned without having to wait for plant stress to tell you.

Consistent Dripper Performance

Netafim pioneered the use of molded drippers and each one is manufactured to the industry’s highest standards. Netafim drippers are injection molded and welded into a wall of seamless tubing. The dripper flow path is not subject to distortion during installation and the clear outlet hole allows water to exit right at the outlet. Ordinary thinwall driplines (tapes) form their drippers by pressing a pattern into a sheet of plastic or into the wall of the tubing. This type of tubing gets stretched during installation altering the dripper’s flow path and since there is no clear exit, the water drips from the seam or fold.

Flexible Dripper Spacing

Rather than choosing a pot spacing to match the spacing of the drippers, Netafim Space-It Dripline lets you choose a dripper spacing that matches your needs for pot spacing – including 12″, 14″, 16″, 18″, 20″ and 24″. Drip lines (tapes) offered by other manufacturers are for Agricultural applications and often only come in 4″ dripper spacing increments. If you wanted 14″ pot spacing, but were limited to 16″ by the tape you were using, you would have wasted 30% of your growing area. Space-It Dripline is available with the most common dripper spacings for potted plants – dripper spacings to fit your needs.

Space-It Dripline Layout

Space-It Dripline is the simplest way to achieve a good, long term quality pot watering system. The general layout of the Space-It Dripline is very simple:

  • Water is supplied to the driplines from a supply header or submain.
  • The dripline is stretched across the top of the pots and is secured at the end connection with enough tension to keep it in place over the top of the pots.
  • For lengths over 100 feet, locate the supply header in the center and install the driplines outward in both directions with separate connections for each dripline.

There are several connection options available for Space-It Driplines. A few of the most common connection options are illustrated in the following layouts. Check with an authorized Netafim USA dealer for other installation configurations.

Supply Header Connections

Several materials can be used for the supply header, Polyethylene (PE) pipe and PVC pipe, are just two of the most common. A light tension is placed on the Space-It Dripline, so the supply header must be secured in place. It can be strapped to a solid fixture or sometimes a few rods of rebar driven into the ground are sufficient. The Supply Header should be raised to the level of the pot so the Space-It Dripline doesn’t pinch at the edge of the pot.

  • Polyethylene Pipe A 3/4” polyethylene pipe is used as the supply header for the Space-It Dripline system in Figure 1.
  • PVC Pipe PVC pipe is used as the supply header for the Space-It Dripline System in Figure 2.

Space-It Dripline End Connections

The Space-It Dripline end connection can be as simple as tying the dripperline around a fixture or using a line end fitting.

  • Space-It Dripline Secured to a Fixture
    In Figure 3, the end of the Space-It Dripline has been folded around a nail that was driven into a piece of wood and then zip-tied securely. This type of end connection is quick and easy, but the lines can not be flushed without cutting the zip tie. Flushing is not usually needed on a short term crop.
  • Line End Fitting
    In Figure 4, the line end fitting is inserted into the Space-It Dripline. This fitting is easily attached to a board or pipe. Flexible cord can also be used to attach the line end fitting to a fixed object. The line end fitting contains a loop which can be pulled to adjust the dripperline tension. The fitting can be removed for line flushing if desired.

Space-It Dripline Design Info

STEP 1

Determine how many pots can be watered at the same time. Use the Zone Flow chart to help calculate how much water it takes to operate one zone of pots with Space-It Dripline. You do not need to operate the maximum amount, but do not exceed the maximum. If the amount of water required exceeds the amount available, reduce the zone size.

STEP 2

Determine how long a row or ‘run’ can be made.
We recommend a row or run length of 100’ or less to limit expansion/contraction issues and general operational practices.

STEP 3

Select the major system components.
Once you have selected the flow of each zone, it is time to size the major system components. Recommendations for sizing basic versions of valves, filters, water meters and pressure regulators for your zone flow can be found in these charts.
