I'm setting up a new grow tent and am trying to think ahead and I thought of shelves. I found some 3D printed gimmicks online but I enjoy the challenge of repurposing shit around the house. Between zip ties and duct tape I feel I should be able to MacGuyver up something ugly but serviceable yet I'm drawing a blank. I'm not thinking of anything heavy duty or plant-supporting, just for odds and ends that are used on a daily basis. Anybody figure something out for their own setups or have any ideas?
