PostHeaderIcon Homemade Potting Bench Using Reclaimed Barn Wood

I made a rustic looking potting bench for our off grid greenhouse using all reclaimed lumber from an old barn that was demolished. The wood was left here for us to use as needed. The potting bench is built to a convenient height for my wife Melanie so that she can work in comfort in our winter greenhouse.

I first took a tape measure into our off grid tiny house on wheels and asked Melanie to walk up to our counter and table top to get a feel for the height that she wanted the potting table to be built at. We came up with about 32 to 34 inches for her comfort.

I hauled out a mess of old barn wood from the barn wood pile and cut the framing to size. I made the back legs of the potting bench 48 inches high. Then I cut the front legs at 34 inches high.

Next I cut the boards for the bench itself and then the top shelf. I used two pieces of 2×10 barn wood at 36 inches wide for the table top. A piece of 2×6 lumber formed the top shelf above the work bench.

I used scrap 2×3 lumber under the bench top for added strength to support the heavy pots and soil that will be used on the work bench.

I used 3 inch deck screws to hold it all together.

When I had the main part of the potting table together, I took the entire thing into the greenhouse for final assembly. Otherwise it would get way too heavy to carry myself.

I cut some treated lumber for the battery bank table down under the work bench. This potting bench will double as a battery rack to keep the off grid solar greenhouse batteries off the ground. I used recycled treated lumber that I had on hand for the battery bench. I figured it would resist any chemicals from the batteries better if anything ever spilled.

I ran out of screws so I had to fire up the generator and air compressor and use the framing nailer to finish the project. I figured that screws and nails give the table extra strength anyway. The screws give pulling strength to keep the wood together and the nails give sheer strength to keep the shelfs from ripping apart under load.

When I had it all finished I put it into its final home and leveled it off with treated lumber scraps. This both keeps the potting table off the ground and keeps the legs from rotting with time.

When I had it all finished I brought in some old Alpha Cell solar batteries and put them on the bottom table of the potting bench. I connected them in parallel to increase the total usable current of the greenhouse battery bank.

Next I connected a solar charge controller and a set of solar panels to complete the greenhouse solar power system. I then connected the aquaponics air pump which provides air for the fish in the large 275 gallon IBC tank. I will soon be connecting water pumps and finish assembly of the aquaponics system.
