Product not great for real plants and watering

Product not great for real plants and watering, gaps in seams. Great for decorations and plastic succulents, which I what I used it for. Very pretty and arrived on time. Would buy again.

I had anticipated this would water my plants in a 360 degree pattern.  But, the water just sprays up.  If you have any kind of wind, it will blow the water away from where your plants are.

doesn't really work, wanted it for my garden to use less water but finally gave up, nothing was getting enough water

Many of my plants have low leaves or some other issue that makes the foam utterly impractical, especially since when I add water to the foam on the soil the foam floats.  I'm so sad that what was once a good product has come to this useless state.  I definitely will be looking elsewhere for my houseplant food in the future.  I'll try adding this to my watering bottle and shaking it up, but the measure will be so different from simply adding a measured amount to the water as it used to be that I'm afraid I'll unknowingly over or under fertilize my plants.

This does work, but probably better used on a temporary basis for existing plants than a permanent one, as the 'flood and soak' system (as it were) can lead to issues if the water is not taken up quickly enough.

My experience does not match the 4.5 star review average for this product. I like the concept of the trays but it did not work well for me. I tried to grow broccoli sprouts. The trays do not drain fully so the seeds/spouts are in a thin layer of water. The trays also do not breathe well. There are tiny holes at the base but not enough for proper air circulation. I found after 3 to 4 days that my seeds smelled spoiled/rancid. I'm going back to the ball jar with a mesh lid. That works much better.

This system couldn't even handle the 12 plants I have on my apartment balcony! Barely a drip half way into the system and I fed the system with a
garden hose so I'm sure it had plenty of pressure the line is just to small to feed the amount of plants it claims.

Good idea, however the dish above accommodates a large plant. The container below doesn't hold enough water(after watering) in my option and experience.

This seemed like a great idea, but the spout isn't glued to the base. Filling it with water results in the water leaking all over, and thereby the plant remains unwatered.

Very light weight.  Requires high water pressure to rotate....causing adjustment to be impractical.  I bought this to put in the center of a vegetable garden. (10x15 area)  I know this sprinkler was cheap but it is worthless unless you are at 15-20 GPM....or over and at that point you would be watering a very large area. I would have returned it but I bought it for my second home and do not have time to go through the drill.

The idea is great, however the pockets are VERY SHALLOW and you constantly have to water your herbs since the soil dries out so fast.  What I thought was going to be an easy herb garden turned out to be wayyy more maintenance than anticipated. This would be perfect for succulents, otherwise wouldn't use it again.

This is a coarse white crystal that was difficult to measure accurately.
I used it on potted pineapple plants and strawberry plants for a month.
I had no noticeable difference in growth rate or blooming between plants treated with this and untreated plants.
Not recommended as a fertilizer for potted plants, you might have better results with hydroponic plants.

I love having fresh flowers around, but it can get pricey. I wanted to extend the vase life of my flowers so I don't have to replenish as frequently (normally 5 - 9 days).  I have used this three times now and each time, it has done the exact opposite of what it's supposed to do. I had a bunch of barely opened irises and with this in the water, they never opened, dried up and died in three days. Next I had beautiful long-stemmed marigolds with some buds. After a day, they looked sickly and dry. I changed the water and used 1 pump per quart instead of 3. It didn't help and the stems and leaves withered and dried up. Next time I will do a test and divide my flowers between two vases with one in just plain water, but I'm pretty sure I know what will happen. I am very disappointed in this product! Maybe I got a bad bottle, but I'm not going to risk buying another one. I was better off using plain water like I've been doing for over a year now.

Not real pleased with the rate of water that drips out. It does a poor job of slowly watering and lets out way too much water. This created puddles in my flower garden and washed out some of my mulch. I never had any problems like this with the regular rubber soaker hoses.
It is a lot easier to maneuver and lay out. However, I had issues when needing to angle/make a turn. The hose would tend to create a small stream rather than dripping out slowly

Not an effective sun filter for sun sensitive crops.

These are better than nothing, but they didn't keep the plant evenly moist.  Also, the wine bottles it recommends were heavy, when filled with water, and one fell over, ripping out part of the plant.  Next time I'll prop the bottle against something.

The can I received seemed decently put together, however due mainly to it's large size, I've found it extremely unwieldy for watering house plants. Peter Paul van Dijk put it as well as I could in his review:

"1. The watering rose is awful. It is too-large-volume, with too many and too-large holes, meaning that you must tip the can well forward before you get enough pressure to get anything resembling fine streams of water. Pour too gently, and all the water just merges into a big, uncontrolled flow that beats down the plants and has no accuracy (the lack of accuracy is not a problem in my garden beds, but it means water wastage and more trips to refill)."

With the only exception being that I'm looking that I'm looking for accuracy as opposed to efficiency.

That being said, it's still a good can if you've got largish beds that aren't too delicate, particularly for the price. (I also found it priced a bit less at my local home improvement center, however the stock supply was extremely low).
