Irrigation system for a large (still) empty plot

Yes, sometimes I want to be too precise....

Which connectors do you use for the cables?
So for 2 cores I still have a few Scotchlok UY2, but I can combine the ground cables directly in the valve box and only use one core to the control. But for me, that means 6 cores that I want to connect. I only found the DBRY-6, which is apparently also used for several cores in practice. According to the manufacturer, however, only max. 3 cores are allowed?

Works also for 6 cores. I have already seen quite a bit in the valve boxes. From just twisted, to with heat shrink tubing, soldered, Wago connectors, etc. I have had no problems with the grease sleeves like the DBRY (10 years).

All right.

I had planned PROS-04-PRS40 everywhere. For the MP800 with the 1.9m radius, I need a PRS30 to achieve the small radius. What about the MP1000, MP2000, and MP3000? For example, I have planned an MP2000 with a radius of 4.2m; does the PRS40 housing work for that, or do I also need a PRS30? Or an MP1000 with a 2.6m radius. Is a PRS30 required there as well? How is that determined?

The 25% radius adjustment described does not fit anywhere. For the MP1000, a radius of 2.5m to 4.5m is specified. If I reduce 4.5m by 25%, I only get 3.4m. Does that mean a PRS30 housing is needed from there down to 2.5m radius?

Best regards

To reach 4.2 meters with an MP2000, you need a PRS30 housing. With the PRS40 and at 75% of the throwing distance reduced, you don’t quite reach 4.2 meters. To reach 2.5 meters with the MP1000, you need PRS30 and the reduction to 75%. As long as you don’t hit house walls, it doesn’t matter if the sprinkler waters 10 cm further. With wind, etc., you have fluctuations anyway. It is not a line laser.

ok.....

I still need to reorder a few things and wanted to order something suitable for the bed right now.
This is also a bit unclear to me.

So far, 2 products seem suitable to me:
Kurzradius Micro Spray and Bubbler/Bubblerdüsen.

Is there anything specific to consider here or is something recommended?

Also use drip irrigation in the bed (e.g. XFS Dripline). That actually works for everything and you are not dependent on sunlight when watering. Saves you the sprinkler housings as well...
