Starting seeds indoors is a great way to get a jump start on your garden. Maybe you have a big pile of small seedling containers for just such a job tucked away somewhere in your basement. But if you don’t, or if you’ve finally run out, this is an easy way to save yourself a trip to the store and to cut down on your consumption of new plastics.

If you’re a soda drinker, start saving your plastic one and two liter bottles. If you’re not, ask your friends to save them. Try to collect darker plastic if you can, as sunlight filtering through clear plastic can discourage root growth. Remove the label from your bottle. Then, using a knife you don’t care much about, stab a hole into the side of the bottle, about 1/3 of the way up from the bottom. Jam the knife point into the hole and cut all the way around the bottle, so you have two halves.

Set aside the top half. You’ll want it later, but not for a few weeks.

The bottom half of the bottle will serve as your seedling container. Before planting, you’ll need to add drainage holes. If you have a drill with a spade bit, that’s fabulous. Drill three holes into the bulges on the bottom. If you don’t, you can simply hammer a nail through the plastic a few times or very, very carefully jab a few holes with the point of your knife.

Next, smooth the jagged plastic edges with a lighter. Slicing through plastic with a kitchen knife doesn’t make for clean work, but just a second of contact with a flame is all it takes to melt that roughness into something more easily handled. Give a quick blast of fire to the top edge and all the holes.

It's a good idea, but I use both parts of the bottle. Just turn the upper part up-side-down and plant in the seeds there and the bottom part fill with water and nest in the upper part. It becomes self-watering seed started fast and easy. I've got more tips on http://gardenersbrixton.org.uk/
