Make a super-easy hydroponics system!

I'm busy, like gardening, and forgetful. Whats the easy way to counter all that, and grow plants? A hydroponics system!

Hydroponics, or the art of growing without soil, is pretty darn simple. Water+nutrients+plant= better than dirt. No weeds! No bugs! No over-watering! No gardening smarts required! Just plop your plants in and sit back!

Here's how to build an easy wick hydroponics system with stuff around your house.

Step 1: What you need

Here's what you'll need for this project.

A plant with a somewhat small root-ball.
An empty spice container, small. The lid must have a flip up top and holes, but the flip-up top can be broken off.
Lid from another spice container, same size, but no holes
Gravel or pebbles
Old T-shirt, sock, or some sort of cotton fabric
Distilled or bottled water
Fertilizer that will dissolve in water
Tape
(Optional) black paint

Where do you put the fish?

Good idea and nice work i had fun doing this. I my self did not have old spice containers laying around so i used a soda bottle. Drilled holes in the lid and chopped the top off and flipped it over. I am about to go get some paint for it soon if the soda bottle works out i will be making more.

I've have a recycled grocery bag full of spice jars I didn't want to throw away. You just made my day!

I may do something like this for an upcoming environmental fair in my area. It's amazing how may people think growing a plant without dirt must be voodoo. I like seeing something like this on a very small scale. My hydroponic garden at home is too large to transport to different places on a whim.
Just a suggestion though: add 2 parts of fertilizer to one part Epsom salt (1 gallon of water, 2 tsp fertilizer, 1tsp of Epsom salt). The added nutrients from the epsom salt will help replace the nutrients that would normally be in the soil.

Kaber et al, I did a similar science project with my daughter a few years back taking off a theme I saw at Epcot Ctr with floating garden in the lakes there. cool; So for starting seeds I took scrap styrofoam laying around the house and cut out circular "biscuits" per se and then cut a center hole (donut like) that would support a single cotton ball. Used a medium plastic container (6" X 12") with 6" sides. Fabricated a black wrapper with just about any black material to block some of the sunlight from sides (garbage bag should work well). I started tomatoes by placing the seeds in the cotton balls and then placing in the donuts so enough cotton was level with the bottom and will remain wet. Germination in just a few weeks and makes a good observation sort of terrarium for kids. Donuts can be lifted out and used for observation/discussion and returned to nutrient broth you have in plastic container. Obviously as the plants get some size they could tilt the floatation device but by that time you should be ready to transplant to another larger device; maybe a regular pot with soil or such. The cotton ball with roots can just be transplanted to new medium. I terminated my project at that point but should be a nice classroom starter project. If I were using it for my garden now (and I may start it again) I'd transplant to a small pot until enough size to later move to outside garden but gives a way to start plants way early inside in preparation for warm temps. Have fun.
