I have to disagree with that assessment. I've planted literally hundreds of these things for my job, they simply do NOT grow quickly, even in ideal conditions until they are mature. Once mature a foot a year is about all one should expect. The Arbor Day Foundation ranks them as a slow to medium growth rate conifer. To make it worse, many nurseries do not carry very large ones for sale, though 6 footers can be had for under $100 a piece retail if you look around enough.
Cultivar matters as well, with some of the dwarf varieties taking 20 years or so to reach 6 feet tall while Green Giant will take much less than that.
