In the spirit of reduce recycle reuse here is a short list for this project.
The bottom of the grow bed has galvanized sheet metal from a roof over I took down a few years ago.
The sides of the bed have 2 X 6 PVC fence used for raised beds.
The screws were from the raised beds. I will also reuse the joist hangers from these beds.
I used IBC’s to catch the rain water.
The 55 gallon barrels reused form industry about ½ were free.
Sump tank was bought off craigslist as were the stands both repurposed.
For others thinking about this type of project and want to start smaller.
Find a couple food grade IBC’s you can even use a Harbor freight pump.
River rock and have close to an 8’ X 8’ growing area. You plant 3 to 4 times denser than dirt plating.
You can put out a lot food in that area and set it up at a very reasonable cost. Some people dress the beds up for better WAF factor.
(Wife Approval factor)
Over to the right is a IBC all covered up.
Here are some creative ways to dress up barrels. These are for other peoples projects. These started out as blue barrels. I am not this creative.
