Functional Scores. 1  See how Procore, Spitfire Project Management System, and BuilderTREND stack up against each other in the major functional areas of construction software. 2  Here's how Procore and Spitfire Project Management System compare in three key aspects - Project Management, Estimating, and Accounting:
A grow bed is a square or rectangular box or tray used for growing plants in an aquaponic system. The grow bed is of similar size and shape to the fish tank in which it sits on top of. Grow beds are often made of recycled black plastic, so their edges tend to absorb heat in the summer and preserve moisture in the autumn.
Building the Garden Bed. The bed frame can be as simple as 2 x 4s on top of the ground, or even patio retaining wall blocks. The size is up to you. A bed that's at least 6 inches high provides ease of access and gives roots plenty of room to grow. These instructions describe building a 4-foot by 6-foot by 10-1/2-inch bed with 2 x 4 untreated lumber. Untreated lumber isn't rot-resistant, but it's a good option for edibles.
