Link works for me on my desktop. Looks great Pete! Thanks for the photos. I agree, there is something great about watching a tiny tree grow into something substantial. The majority of my plants started as puny mail orders. Only now have I started buying larger size plants and stretching my plant budget.

Not great lighting for pics, but a couple spruces are doing their thing: Picea pungens 'Procumbens' It used to be very stiffly horizontal, but the left side started upturning last year or so. Usually even more intense blue. Picea abies 'Pendula' Picea glauca 'Rainbow's End' Picea pungens 'Thume'

Ah ok, i see my question is perhaps not worded great. I realize jack posts come with various load capacities. When an engineer designs a house she needs to calculate the load barring capacity for each post based on the weight of the house and span and height of the posts. However, I also know that hardly anyone goes though this math when they build (just like we don't for determining the span of 2x4 it's standard to use 16 inch). Post and beam construction also has this type of standard. given the standard span of 9 ft and 7ft height, i'm looking for the standard load bearing capacity for the post. I'm pretty certain it's over 9100. That's a temporary "light duty" 2 part adjustable post for sure.
