Self Watering Pots
Ok, so I'm new to growing a lot of stuff in pots and thought I'd try some self-watering ones since it can be VERY difficult to keep up with watering here in Las Vegas between the heat and the near constant drying winds.
Two of my new pots are your typical self watering pot with the slot in the side to add water to, and a wick-thing in the middle that makes contact with the potting medium - they seem to be working great.
Today I just got a really big pot (20" for a small tree), but it has what the vendor calls a "self watering disk" - which basically looks like a form fitting, perforated shelf like thing that sits in the bottom of the pot. No external hole or slot to water a resevoir, and no wick material. Has anyone used one of these before? Am I supposed to cut my own hole and supply my own wick?
Here's a link to what I bought (are links to Amazon allowed?)
