Automatic Watering System 6-Piece Set Value Offer: 3-Medium and 3-Large High Capacity Resevoir

These are perfect for when you are on vacation and there's nobody to water your plants. I have two sets and recently went away for a week. I used these and when I came back (after a heat wave where it was 90 degrees or hotter for most of the week) the plants looked great. I suggest using the larger for most plants and I used more than one for bigger plants. The only downside is if the soil in the post is not high enough you may have to add more or these won't work in that pot because they are not very long. I would definitely recommend them.

These are nifty gadgets!Just remember to glance at the water level, which is not hard as long as you have the clear strip where you can glance at it. I didn't have them turned properly the first several days.

Visually unobtrusive compared to the spikes using water bottles. Keep my potted plants watered in the hot valley summers!

Most of these work well but some don't deliver much water. You will probably have to add soil to your pot. You have to watch that the top does not come unscrewed. I have multiple waterers in the thirsty plants but they can only go about 3 -4 days before needing a refill.

Gives plants consistent water supply.

These watering aids are very effective. I use them indoor and out.

Not long enough and falls out easily

Great idea however, it could use a few tweaks. The water is dispersed too quickly and the tip does not extend out and deep enough for large pots.
