Step 3: Fill with dirt, water, and plants!
Remember, use a cheap potting mix. You can try using a layer of fertilizer put down first right on the shelf, tell me if it works out! Get it really packed into the rigid cups, and get that soil soaking wet to make sure there are no air bubbles there.
Make sure to have the container where you want it to sit before filling the water reservoir, or it will be crazy heavy.
I planted coffee plants, and tea, stevia, and jalapeno seeds in here, I'll post the results in a few weeks.
Make sure to put a black garbage bag over the top once your plants are big enough to peek over the surface of it. Cut X's in it for the plants to poke through, and use what's left of the lid to secure the bag. This will conserve water, keep the soil more moist, and maybe keep things a little warmer.
You can be cool like me and add a grow light. I'm going to experiment with LEDs in the future, and you should too, since they're awesome.
Good luck, and I hope you've enjoyed my first instructable!
-Does anyone think an aquarium airstone and pump in the reservoir would make a difference?
-Also, if a hydroponic medium if used in place of dirt, do you think this setup would make a good wicking system? What mediums would wick enough to do this? I've heard that using a rope wick leads to clogging and crystallization and suspect that this wouldn't be as much as an issue if the wick was two 3-inch columns of the medium itself.
