Why Use Algreen Self Watering Planter?

It's Easy and Convenient

That is the best reason of all to invest in self-watering containers. They make your job as a gardener easier. Sure, watering your plants when you only have a few is easy enough. As your garden grows, it can become quite a timely task.

Forgetting to water can be devastating! Did you know over-watering can be just as catastrophic? Self-watering containers help with both.

It's Healthy - Bottom Watering is Good for Your Roots

Providing water from the bottom is highly recommended for many plants. Especially when it comes to young and containerized plantings. When a plant searches for water, it extends its roots. Watering your plants from the top makes your roots lazy and keeps them from searching.

Common Watering Problems That can Solve

Life happens. You can easily get caught up in the day-to-day working of everyday tasks and forget to water your plants. It happens to the best of us. Next thing you know, you have wilting plants that are dying of thirst.

Taking a trip can also leave you needing a plant sitter. Gardens do not travel well, so they will need to stay behind if you plan any lengthy travel that could cause devastation. You will likely need somebody to come in and water your plants.

A common mistake of new gardeners can be overwatering. This little no-no can be just as harmful and sometimes worse than withholding water at all.

A Bit of Growing Freedom

Time-saving and freedom allowing. Self-waterers allow a bit of space and options when it comes to your plants. They are straightforward to use and do not take much to set up.

Algreen Self Watering planter adds even more with its ease of use. Besides, an easy-to-read indicator tells you exactly when your plant needs to watering.

Water pours into the side of the unit no matter what direction it is facing. When your plant needs fertilizer, it can easily be added to the water reservoir saving even more time.

The Algreen construction is also shatterproof. Making this convenient for households with pets and kids. Even if it gets knocked over, there is no need to worry about broken glass.

Many Options Available for Self-Watered Freedom

There are many choices on the market for self-watering containers. They range in size and style. The Algreen Self Watering planter reviewed here is just an example of those options.

In comparison to a similar brand and style, the Lechuza. I would pick the Algreen. For me, it comes to price savings. The Lechuza is a nicely made planter but is at least $20 more expensive. Besides, it requires a special soil material to make it work. I called Lechuza Pon.

They are a beautiful planter that is almost identical looking to the Algreen. Ultimately, I get all the functionality I want at a price I can live with. I will go price every time.
