Steffie N.

Great product!!!! Always my pleasure!

Mario G.

Expensive, but great!

Roswitha F.

Watering works great, my zucchini thrives wonderfully in the pot

Günther R.

aaa

Evelyn R.

I ordered the Ollas to integrate into my raised beds. Since the raised beds aren't finished yet, I can't give a review yet.

Rosalie S.

All good. Works fine.

Zulfiya M.

I really like these clay pots. This irrigation method has apparently been used for over 400 years. They also help my seedlings. I can only recommend this watering method.

Evelyn R.

I can't say anything about it yet. I bought the product in advance to use it later in 2 raised beds

Marion G.

Nice for plants that can't be watered for a few days.

Gudrun L.

Great

Sabrina E.

Wonderful product and it works absolutely satisfactorily. Unfortunately, it seems to me that the material is very susceptible to breakage and two of the four vessels looked as if they would break when they were received. I'm excited to see what it looks like after this year's session. Therefore 4 out of 5 stars.

Nico H.

Really very good quality

Thomas P.

very good

Rainer W.

After 2 weeks of use, I am fully convinced.

Markus K.

Great product

Silke R.

I am very satisfied. After I bought two larger vessels, I ordered three smaller ones a little later.

Katrin S.

Very good. Good quality.

Katya R.

The Ollas work wonderfully

Bernd S.

Didn't expect this success. We can now go away for a weekend and we haven't had any wet houses yet. Are very satisfied

Alexandra R.

Everything went fine.

Reinhold A.

Great quality, good price

Claudia R.

Delivered quickly, dug straight away and I was saved from having to water the raised bed every day. Thanks!

Maria D.

Fast shipping, great product

Corinna H.

Great for watering raised beds!

Elke M.

I am very happy with the Olla.

Ulrike K.

Great, I no longer have to water every day!

Julia H.

The irrigation works perfectly. I refill water every seven days.

Andrea Z.

The Ollas are perfect. An Ollas was delivered broken and was delivered again immediately after a complaint, the customer service is very good!

Elizabeth B.

I had very good experiences with the medium size and gave the smaller size as a gift. Would buy it again.

Angelica R.

Works great!

Maria D.

Great ollas, fast shipping

Jens F.

Top quality

Hanne B.

Prompt delivery, a great system. In the vegetable garden, vegetables grow excellently despite the heat. Lettuce, kohlrabi, beetroot, cucumber, peppers, zucchini. Just great, the system!

Jacobsen U.

I use the Ollas in raised beds or balcony beds. I am very satisfied as the plants seem to be well cared for. In the raised garden bed, the rather dry surface soil seems to make it difficult for the snails to move forward. So far I haven't had any significant snail infestation, but that may be partly due to the long period of frost and snow.

Beth D.

I'm so amazed how well this works. I absolutely. recommend this for anyone who wants to plant a garden and still take a vacation.

Diana M.

That's great, you only have to fill it every 3 days and the plants are well looked after

Constanze H.

Keep what you promise.

Andreas S.

Everything is fine!

Ulrike K.

I discovered and bought my first organic Green Ollas from Dehner a year ago. The test in the flowerbed on our terrace was extremely satisfactory. Reason enough to also equip our other beds with Ollas. This time I ordered directly from the manufacturer. We enjoy not having to water daily anymore and also save water with this system. Short vacations are now possible without having to ask neighbors to water.

Gabriele K.

Practical, sensible, and also beautiful

Beth D.

This makes going on vacation so much easier without having to ask neighbors to come over and water my garden.

Michael B.

At least my tomato plant is enthusiastic.

Stefan H.

Fast delivery, good product.

Magiera M.

So far I am totally thrilled with the Ollas. They have saved me a lot of time and water, this is the first year and first time in use for me. But I can recommend it already.

Nico H.

Super quality

Andrea P.

The gourds help great with watering

Stephanie H.

Fits!

Beth

Thank you, it is exactly the size for my above-ground beds. Looking forward to a great growing season

Mr. R.

Everything great!

Mr. R.

All the best!

Steffen H.

Nice and direct contact for questions about delivery

Beth

Exactly what I wanted, can’t wait to start planting

Monique F.

This is already my second Hydromax, the first served excellently for many years. During installation in the spring, I had a small mishap... so I was glad that these little guys still exist.

Rüdiger K.

Great idea, now we can go on vacation relaxed

Nadine R.

Already ordered 2 last year. I’m thrilled.

Martina K.

Very good workmanship on the Hydro Max Olla, because of the favorable price, I immediately ordered several more as gifts. Looking forward to a good harvest in the raised bed and with less water consumption.

Antje K.

As always... everything great!

Irena P.

Last year I used both L and M sizes of Ollas. I was very satisfied and this year I ordered even more M-size (3.5 liters) because they fit better in my beds. I am fascinated by this type of irrigation. This form is suitable for vegetable gardens. For perennial or shrub beds (like hydrangeas), this form is not suitable because when digging in autumn, the roots of perennial plants are damaged. For those, the shape with the cone pointing downwards is better. I made one myself by closing the hole of a ceramic pot at the bottom. In autumn I took it out, dried it, wrapped it in a plastic bag, and put it back into the existing hole for overwintering. It would be good if they offered something like this.

Antje K.

Great.

Antje F.

High-quality goods

Antje F.

High-quality goods, thank you very much!

Michael V.

Everything went perfectly

Renate S.

Still in the box, still in the process of setting up the raised bed.

Petra S.

With the olla, you save a lot of water and time!

Beate P.

The processing of the order was quick and reliable. The reduced price unbeatable. I have already had 2 ollas of 3 L each in the raised bed for several years. They are a great help, especially in midsummer. How the small ollas will handle the tomatoes in the pot will show itself next summer. I expect, however, a good result.

Uwe A.

The ollas work exactly as described. I have now purchased more after using the first ones for two years.

Barbara D.

I gave the ollas as Christmas gifts, and they will go into the future raised beds in spring. Therefore, I can only report on the delivery and goods. Delivery: very fast and packed securely against breakage. Goods: intact and very good quality. Many thanks

Christina W.

Very nice ollas. But they will only go into the bed in spring.

Pamela K.

Since I ordered it at the end of autumn, I can't write anything about the use yet, but the delivery was fast and the items were well packed.

Cordula D.

Super easy to use

Mr R.

Everything was great

Stephane M.

I'm looking forward to the 2026 season

Kimiko Vanessa P.

Keeps the plant well watered and makes not watering it once less of a deal. Just wished there was an even smaller one for really small room plants.

Sabine K.

We are very happy with the Ollas. We watered cucumber, pepper and tomato plants this year and are super satisfied. We also had mulch on the plants and therefore only needed to fill up the ollas once or twice a week and the plants had enough water. Unfortunately, one of Olla was broken when it was dug up. Delivery took a little longer, but everything was okay!

Marion R.

Works great, absolute purchase recommendation!

Annegret B.

I gave the order away
