I was shopping at Manhattan's 23rd St HD when I came across this planter, the Jumbo Growing Tower from the HDR line of Southern Patio. This is the first self watering container I've ever seen sold in this store. I bought one for the roof, $15.98 plus tax.
The planter is 15 inches wide and 12 inches tall. The soil chamber is 8 inches deep and the water reservoir is 4 inches deep.
Remove the black divider and you see the caging kit stored in the bottom of the container.
The caging kit consists of 9 sticks and 3 rings. It's very easy to assemble
The label says the planter with the cage reaches 59 inches, but I measured only 45 inches. It would reach 59 inches, however, if a 4th ring and set of risers were included in the package. I assume at some point the company changed their mind and reduced it to a set of three and never bothered to correct the label. Either that or I got an incomplete kit. I don't care enough to pursue the issue, but if someone else buys this planter and they get a 4th ring and set of risers please let me know so I can update this post.
The label also states the water reservoir holds 2 gallons of water, but I was able to fill it to a little over 2.25 gallons.
The planter and the green sticks for the cage are made from a hard plastic. The black divider and green rings of the cage are made from a softer, bendable plastic. Does this matter? Time and the elements will tell. I'll let you know how it does on the roof.
Southern Patio Jumbo Growing Tower: $17.40
Running Total: $113.95
Update: My thoughts after five years of use.
As I suspected all the hard plastic parts have held up well and the soft plastic parts have had a tougher time. One of the green rings has a broken arm and a small section of the black divider broke off when I got a little too aggressive with a garden spade, but both of these things were easily fixed with some duct tape.
The support cage cannot support anything heavy, I use it only to keep leafy growth in check. Don't rely on it to support a tomato plant.
The support cage struggles in high wind conditions. The sticks and rings fit together well, but they do not lock into place. If all 3 tiers of the support tower were used and it was a windy day the tower would sway so much a few of the sticks would often come loose from the rings and fall to the ground. More of an annoyance than anything else.
I don't regret buying it. I wouldn't buy another one for myself, but I would recommend it to someone thinking about getting into gardening. It's a good entry level product.
