I would like to know how to manage the following garden.
I currently have 5 areas of lawn and other plants, with 3 Hunter PGP sprinklers for each area. Of these 5 zones, there are two with a lot of shade, and the rest are sunny (central Spain).
On the other hand, I have another zone with 6 diffusers, and a last one with a drip system for the Leylandy hedge.
I am interested in acquiring a Spark programmer but... how many Whisperer would I need?

How does Spark differentiate between the different zones and how does it combine the amount of humidity needed? The type of grass I have is made up of Raygrass, Fescue, Poa, and Agrostis. I could send you a plan of my system for your advice.

the outer lines indicate the individual irrigation fields.
AREAS A1 - A2 -A3 - A4 -B1 and B4 are the shadiest areas.
These areas are shadier due to the height of the hedge.

For orientation, a straight line between points 13 and 8 marks the North-South line, where 13 is South and 8 is North.
Neither the diffuser area nor the drip line of the hedge is represented here.
The water inlet is located in the legend E1, between sprinklers 12 and 13.

Thank you very much.
