Actually a year later
This one was a replacement I accidentally broke over the winter. I originally got them last spring. They work perfectly for what is needed. And if you Square Foot Garden, 5 of these small ones is perfect for a 4x4 bed. It definitely made last season so much easier to manage in regards to watering and irrigation. I'd just go out twice a week, or 3x if it's really hot to refill. My plants definitely benefited last year. So I'm looking forward to season 2.

Works like it’s supposed to. This one holds less than a gallon of water but will definitely help plants that are newly planted

Best way to water raised bed
A friend gave me a small size, and I liked it so much I bought a medium one for my raised bed. I just planted seedlings of carrots and Swiss chard. The carrots circle around the small one, and the Swiss chard encircle the medium one. The water is released slowly down to the roots, which is better than spraying the top of the soil.

Do not buy the 4 pack option!!! It will only be one in a box
If by chance you clicked the 4 peace option this is what to expect. 1 peace in one box I ordered the small size and it was supposed to be 4 not just one.

SMALL SET OF 4 is not true
Yeah the product description is wrong. I just checked and it still marketed as SMALL SET OF 4. Do NOT BE FOOLED, ONLY ONE POT COMES. ONE. I had noticed that one pot was pretty much the same price so I thought maybe I'll get lucky. But no so definitely just one pot. The quality is good so I would purchase from brand again but maybe not the small.

Flow flow flow
I bought a similar product which works well. But this is LARGER. I have thirsty vegetables that feeds off this. They are flourishing. My advice dig deep to place in the ground, make sure you leave a little part of the neckline out. I’m in the south so my summer days are long. Make sure you still water your vegetables along with adding water to o the bottle to keep the soil moist for longer

Saves my planters
These things save my plants on my porch where my sprinkler system doesn’t reach. I have to fill them up about once a week right now in the spring. The constant moisture did create an issue only once - mulch mold. But I let it dry up for a while and it went away. I do love these things and have them in many outside planters

Self watering system
This works GREAT, it has kept my Rosemary herb alive since I’ve been using it. In the past the rosemary kept drying up and dying
