My Raised growing bed at work

[amideutch]

Just got done prepping my raised growing bed at work for another growing season. Last fall put in horse manure and last week added organic ferts, micro's from one of Germany's extinct volcanic regions and 160 liters of organic growing soil mix. Been working this bed for 3 years and it keeps getting better. It' right up against the building I work in and is facing south. The walls are sheet metal with insulation sandwiched inside. They absorb and emit heat which makes the plants thrive. Here's some pictures of the raised bed at the site to include a couple pictures of the Heliport next to the site. Ami
