Automatic irrigation with time-saving

Using a Gardena irrigation programmer, your garden can be watered reliably and conveniently - even if you are not at home. Enjoy more free time, a lush lawn, and also, beautiful and healthy plants. If the programmer starts in the early morning hours or in the evening, less water evaporates. This saves money and ensures targeted, optimized irrigation.

Easy Operation

The water programmer can be easily set up using the rotary switch for data selection and confirmation. A clear LC display shows all settings at a glance. The waterproof control unit can be detached to make adjustments. Thanks to an optional lock, accidental adjustment of the settings can be prevented.

Flexible watering with 3 programs

You can create 3 different watering programs. You can set the start time, duration, and days of watering. Adjust highly flexible programs according to your personal preferences. Plant experts use this feature for pre-watering to prepare the soil for the main watering. This improves water absorption and plant growth.

'Water Now' function

If watering needs to start immediately, it can be activated manually without removing the programmer from the tap or changing the settings.

‘Safe Stop’ technology

The water programmer always operates reliably due to the "Safe Stop" technology. If the battery energy levels are too low to fully control a watering program, then the program will not start. The battery level indicator on the screen also informs you when the battery needs to be replaced.

Water-saving function

When you connect the GARDENA soil moisture sensor, the automatic irrigation does not activate if the soil has sufficient moisture. This allows for better water supply and savings.

Good purchase at a good price. There was another one with the same name and code 1891-20. I don't understand what the difference is even though this one costs about ten euros cheaper. I bought it to replace an older Gardena that I had, which had a problem with not being able to close at a preset time. Obviously, the closing command had burned out. The good thing is that I attached the new screen to the old system and it was fully compatible with the old base, a multicontrol

    It is a very good and practical programmer, suitable for a balcony or a small garden. The screen helps a lot in use although not completely necessary. The different versions of the model that one may find (1891-36, 1891-20) have no difference, they just have a different code depending on the country where distribution is made. The one with code 1891-36 seems to be slightly cheaper than 1891-20, I suppose because it is an independent import. Gardena suffers from the diaphragm valve that needs to be changed every 2 to 3 years (Cost 3€), otherwise they are quite reliable while most spare parts can be found. I had previously 2 programmers 1030D (very good and reliable programmer, which is no longer available) but they gave up after 12 years, both at the same time! The gap between the screen and the body of the programmer that some complain about, no longer exists, they have fixed it. So if you receive a programmer that has this gap, it will likely be an outdated model.

    On the 2nd day of operation, the solenoid valve was not functioning. The previous Gardena programmer worked flawlessly for about 10 summers. I am very disappointed with this particular product. I expect a replacement or a refund. In case of replacement, I will update the review.

    I have the older model which works continuously and has been exposed to weather conditions for over 7 years. I bought this model because I wanted another one, hoping it will last like its predecessor, it is easy to program.

    Easy-to-use watering programmer with good build quality and many different watering programs. If it withstands time, as two previous ones of the same brand but simpler lasted over a year each until the body cracked and started losing water, then we will be talking about an excellent purchase.

    A quite expensive but reliable device. Especially for places where visits are not frequent, the use of something reliable is necessary. I once used a cheap one, went to the vacation home after six weeks, and found everything dry. Since then, I mainly use these specific ones and have never had any problems.

    I have an old one of the same brand for over 10 years without a screen, very reliable but difficult to navigate. This one is very easy and understandable to navigate. I believe it will be just as reliable as the old model.

    I had bought one from a supermarket but it was completely unreliable, and I threw it in the trash. The Cardena works perfectly so far. The quality and ease of programming it, light years away from the supermarket one and definitely not comparable.

    It is as described, however, it has one significant drawback. When I program it to water from, for example, 23:30 to 00:30, it only accepts the first 29 minutes, that is until 23:59. In order to continue watering after 00:00, I would have to create a new program, and this is a problem because it allows for only a total of 3 programs throughout the day. In other words, you cannot water continuously with the same program from some time before 00:00 to some time after 00:00. Other than that, it is a commendable product with the quality of Gardena.

    I bought it for the ease of programming, I threw away the user manual because the setup is very easy and straightforward. I also bought it for its reliability and German build quality. I have another one from Lidl, which is good but so complicated that I had to keep the manual saved on my phone because I would forget how to set it up. With the Gardena, I can relax!

    Reliability Gardena. After spending quite a bit of money on various cheap irrigation timers that would work when they felt like it, you programmed them and they did their own thing, I ended up, like many others, with this one. You pay for it ONCE, it is easy to program and you can program exactly how much time you want and you don't have to worry that the battery will run out and the valve will stay open watering until you return from vacation...

    It is one of the easiest to set up for watering. The main difference from other watering programmers, even from the same company, is that you can set up 3 different waterings for the same day, regardless of the time and duration, that's why it shows P1, P2, P3 on the screen. While the usual limitation is every 12 or 24 hours. Another thing I noticed is that when the battery dropped a bit in performance, after 7-8 months of use, it showed an indication of half the battery. I didn't replace it in order to see how long it will last and what behavior it will have. After a month, it still works fine, without any change in the indication. It's worth its money, and it also seems to have a quality construction. I will come back after some time for further information.

Το έχω περίπου 2 χρόνια. Δυστυχώς κατά το 2ο έτος, η μπαταρία 9V διαρκεί περίπου μία εβδομάδα. Μήπως ξέρει κανείς τι συμβαίνει; Έχω δοκιμάσει επαφορτιζόμενες και μη μπαταρίες, καινούργιες και παλιές, και πάλι τα ίδια...

Είναι πλήρως αδιάβροχος ο μηχανισμός; Ρωτάω κυρίως για το αποσπώμενο κομμάτι εκεί που έχει τα κουμπιά μήπως παίρνει νερό. Ευχαριστώ.

sakismat

έχω ενα παλιό με παρόμοιο αποσπώμενο μέρος πάνω από 10 χρόνια. έχει φάει πολύ βροχή και ακόμα δουλεύει. Το συγκεκριμένο μοντέλο το πήρα γιατί πιστεύω οτι θα είναι το ίδιο καλό. Δεν έχω δεί κάποιο πρόβλημα με το νερό σε αυτό το μοντέλο ακόμα.

titos.

επειδη θελω να το τοποθετήσω σε χωράφι που ο δήμος κόβει το νερό όποτε θέλει, σε περίπτωαη που έχει προγραμματιστεί πότισμα και δεν έχει νερό, θα χαλασει το προιον ξερει κανεις;;;
ευχαριστω

christos.zervos

Δεν βλέπω κάποιο πρόβλημα. Θα ανοίξει η ηλεκτροβάνα και θα παραμείνει ανοιχτή για όσο διάστημα προγραμματιστεί αλλά νερό δεν θα περνάει. Δεν έχει κάποιο περιστρεφόμενο εξάρτημα που να χρειάζεται να ψύχεται ή να λιπαίνεται από το νερό που θα κυκλοφορεί.
