Super easy to put together.  Light weight.  Great for starting seed trays.  My suggestion for this rack system is to include zip ties to affix the shelves to the rails so they don't slide around (which I ended up doing).  Also, if you are planning to put heavier pots on the shelves, like I did, I had to wrap a bungee cord from side to side on each shelf as they flex and the rails pull out of the holes and the shelf collapses.  The rails are only pressed into the side pieces. Otherwise I love the size and you could easily start seeds in your home in Mar or Apr. as it is very compact and will fit most anywhere.
