Step 1: Searching for the Goods
Step 2: Clean Up and Spruce Up.
1) Wire Brush for getting rust off of the metal(and all of the paint at that).
2) Dish Soap
4) Spray on Enamel
Once it was all cleaned I spray painted it with a protective enamel that was black, so it would draw as much light as possible and look as much like a smoker as it is. You however could do whatever you like. Paint a picture or scene on it or make it rainbow colored, it is up to you. This project should be about creation of what you envision. There is no wrong choice. I would also suggest if you have not cleaned your rusty, dirty whatever you are using, you should definitely put some plastic covering or something over the entire inside before you proceed to the next step to prevent anything horrid from leaching into your plants and soil.
Clean it and let it dry. Then spray the enamel and again, let it dry. These were my steps, your could be the same or vary.
Step 3: Planting Materials
1) A bag of stones,rocks, pebbles, etc. that was used to help with drainage and ensure my soil didn't stagnate.
2) A spade or implement that you can use to situate the soil(or you can get your hands dirty, your choice!)
*This is a tricky issue. What you want to grow will be up to you. However the stuff you grow will have its own preference as to the type of soil you will need for growing. You should decide what you want to grow before making any hasty decisions on soil. I assure you, if you are buying it, it costs real money and you might need more than one bag. You should also try to know what kind of additives(such as fertilizers and nutrients, as well as your decided pest control method...) you will need and pick it up from a local nursery in one fell swoop.
4) Knife to open stuff
I had originally chosen strawberries to plant(I did this at the beginning of spring in South Florida) but they didn't turn out to be so great in this application and I transplanted them into a different pot where they were fine. Maybe later I will go outside and take a more current photo of the garden we have going. We choose to grow food to help offset costs and frankly because we grow yummy food. Okra, peppers, squash, whatever you desire you can generally grow in a small space and with a little work you can grow a fun and delicious pass time. Plus it can teach you a little about the world around you while you watch your crop come to fruition. Ultimately what you grow is up to you as stated before. What do you think is pretty? What smells would you prefer to have when you are near it? Think about what you grow so you can gain the maximum benefits out of the things you will invest your time in to growing.
Step 4: Planting and Enjoying(w/ update and new photos)
Now you can just open the bag(s) of rocks and pour some into the smoker until you have a uniform amount on the bottom about 3 to 6 inches deep, depending on how large your planter box is of course the amount needed will vary. Just use your best judgement, it doesn't have to be an exact science.
After your rocks are in, throw the soil on and put your plants or seed right in. the exact method will depend on, again, what you grow. Then its all a waiting game. Wait and see what goes wrong first and fix it. Then wait some more till the next issue comes and fix it too. Repeat as needed and ENJOY!
Update: Well, This instructable got featured so thanks to whoever chose me for that honor. As I had said I would update this with more pictures and was bestowed honor from the original, I actually went out and took some photos. Currently we have a jalapeno and a poblano pepper plant in it, as well as what I can only assume is the most cilantro ever privately cultivated...
Now if you know anything about cilantro you know that when it bolts(flowers) it renders it bitter and not very tasty. However the seeds that will drop from the cilantro are actually coriander, so we are just waiting till it seeds and will start again and have some fresh spice at that.
I also took a photo(the last one on this page) of the morning glory that we planted at the feet of the newly minted plant box, which promptly grew up all four legs. So just for reference if you are interested, you can plant ivy, morning glory, or any other climbing plant or vine up the legs or base of whatever you are making for another natural but beautiful effect.
