Blumat Plant Watering Device - Easy XL Self Watering Planter Insert for Indoor Plants - Bottle Adapter - Prevents Overwatering and Underwatering for Healthy Growth - 2 Pack

The media could not be loaded. Good quality product, looks and feels sturdy, combined with my Raindrip irrigation system, works perfectly. Plants are happier, no wasted water, no overwatering. We have over 100 F temperature, this makes vacation possible!!!

Works great. The trick is to only put a pin hole in the end of the two liter bottle. The water lasts about 5 days. But this is a very thirsty plant, so yours might last longer. After reading lots of complaints about the flimsy cheapo ones, I decided to go with this one. Money well spent!

Picked up a few sets of these when prepping to be away for several weeks. Used on plants both indoors and out. They do work - but you have to remember to punch a hole in the bottle you use or the water won't gradually drain (and make sure you have enough bottles on hand that fit these devices!). My only beef is that they're on the pricey side for what they are.

We do not have a drip system so bought these to keep our tomatoes and pots watered while away for the weekend. Work great

water only lasts about three days. Bought because I am going on vacation for two weeks and this will not do the job

this incredible product is pricey but worth it, they kept my plants alive while i was traveling through the heat wave of L.A. highly recommend!!!!

I've used a 20 oz recycled water bottle to keep my planter with herbs hydrated. It works as advertised, and I'm happy they are still living in this Texas heat. I had hoped it would last longer than 2-3 days...but that's much better than relying on me to water everyday. Would recommend and would purchase again.

Coni in materiale naturale (no plastica) senza nessun scendi goccia, che dopo qualche tempo si otturano i fori. Semplice, economico, ottimo. In base alla pianta e per quanto sei assente decidi la grandezza della bottiglia da inserire. Altro non devi fare. Perfetto.

Habe jeweils eine Flasche angesetzt, wie beschrieben. In echt wenig Zeit war diese leer. Selbst eine 1,5 Liter Flasche war in weniger als einem Tag leer. Ich hatte gehofft, es würde zwei Tage reichen, um so ein Wochenende abzufedern. Schade.

El producto se corresponde con lo anunciado. Mantiene una maceta grande húmeda una semana.

Cet adaptateur bien pratique donne de l'eau au plantes en continu et de façon parcimonieuse. De plus, aucun gaspillage, je réutilise mes bouteilles plastique. Dommage que la partie plastique ne soit pas plus solide.

OK, I went thru several of these products before the penny dropped, so I'm going to post my conclusions on all 3 products tried. I'm going to review the large Blumat (0.3l/day), the small Blumat (0.2l/day) and the long terracotta water spikes, for example the Warkhome Water Spikes.As you read other people's reviews, you will get confused. Some people will love a product, while others will say "useless; didn't work for me". Normally you can dismiss the odd 1 star review, but in this case the reviews are so conflicting, you can't come to any conclusion. The reason is that there are totally different use cases being considered.Use Case 1 is individual indoor pot plants, where you put one waterer next to ONE plant to directly feed its roots. Use Case 2 is outdoor plants, and plants in large enclosures, where you put one waterer in an area to feed a FEW nearby plants. For indoor and single plants, you may get away with a low flow rate of under .1 litre/day, which is about what the Warkhome units provide. But if the plants are outside and getting the soil blasted with solar energy, you will need .2 or .3 litre/day. (And if you live in Arizona, you should be grateful that anything can survive that sunshine while you are there, and not expect any of these to work while you go on holiday for a week!).There are 2 different principles of watering being used here. The Warkhome type terracotta spikes are porous pot, with flow limited by the rate at which air can seep up into the bottle and relieve the partial vacuum formed at the top of the bottle. Without air getting into the bottle, the water can't seep out. The bottle fits into the neck of the spike roughly enough to make a partial seal, which is enough to limit the flows of air and water, hence the slow flow rate.The Blumat is totally different. Here the pot is fitted with a plastic neck, so that it completely seals with the inserted water bottle. Then how can the water get out you ask? Well, you have to puncture a hole in the top of the bottle, then it seeps out at .2 or .3 litres/day. (If you puncture a hole in a Warkhome bottle, all the water will just gush out in a few seconds!).I recommend to buy GREEN plastic water bottles of size 1 to 2 litres, as anything smaller needs filling too frequently, and the green blends in with the plants quite nicely. With the 2 litre bottles you will get:Warkhome: 2 litres discharged in about 14 days (this is a rough guess)Blumat.2 @.2l /day: 2 litres discharged in 10 daysBlumat.3 @.3l /day: 2 litres discharged in 7 daysSo now you need to calculate which one of the three to buy, and the answer is obvious, and you already have the data. How often do you water the plants in question? Suppose you have a large outdoor plant box that you water once a week in Summer to keep them alive. You will need one of the Blumat adapters because it is outdoor. Now if your watering can size is 7 litres, you know that your windowbox needs 1 litre per day.That is provided either by 5 of the Blumat.2, or 3 of the Blumat.3If you put the Blumat.2 it will last 10 days, and if you put the Blumat.3 it will last a weekActually, since you water your plants before you go away anyway, it will last longer than the above, but you get the idea.Anyway, so then your choice is between having 3 bottles or 5 bottles visually cluttering your plants. Or, the choice could be between using 1 litre green bottles that disappear but need frequent refilling and 2 litre green bottles that are more visibly intrusive. It's upto you, but now you can choose the balance you want between strict functional requirements, aesthetics, and re-filling convenience.If you are using the Warkhome type spikes, you can just stick lift the bottle out of the spike, to refill it, because it is only a loose fit. When you put it back, just put 2 fingers over the bottle opening, invert it, then slip it quickly into the spike's mouth. Only a small amount of water will leak out while you are doing that. If you are using the Blumat, it is tightly sealed into the pot so if you lift the bottle it will pull the pot out as well. This is not good because it is disrupting the join between the pot and the soil, apart from spreading dirt into your home. Instead, it is best to drill a hole in the bottom of the water bottle, big enough to take a funnel. The hole needs to be surprisingly large, say around 16mm, in order to take a reasonable size funnel. If you use a small funnel, it will take too long to fill. Also, if the funnel completely seals the hole, you need to punch another small hole somewhere else near the top, to allow the air to leak out as the water comes in.Hope this helps!
