One large container with multiple plants coming out of the side
I have this idea for a container garden consisting of one container. I'd like to turn this into "The Salsa Machine" hahah. Here is a drawing:
This is a top view and a side view. The large container is a 32 gallon Rubbermaid Roughneck trashcan. The smaller circles represent 2 liter soda bottles with the tops and bottoms cut off.
Would it be possible to fill this thing with soil and grow onions at the top of the trashcan, pepper plants out of the top pots/holes, tomatoes in the second tier of holes and then misc. herbs in the bottom tier?
I would find a way to have the tomatoes staked / trellised. I could also stagger the pots/holes to help with lighting.
Provided everything was draining well enough and if I went organic with the nutrients do you think that this is something that could be accomplished?
