Seed Starting With (FREE) Self-Watering Planters
Save yourself time and start your seedlings in a self-watering planter made of re-purposed materials.
You’ll need the following:
- Empty plastic drinking containers with lids (8oz, 12oz, 1 liter, 2 liter soda or water bottles) that are symmetrically shaped
- Cotton yarn or string
- Box Cutter
- Common Nail, Nail Setter, or anything that will assist in punching small holes in contain lids
- Soil (we use Sun Gro’s Metro-Mix for our starters)
- Seeds
- Water
You want to punch multiple holes in the cap large enough to slide the cotton yarn through them but not so large that soil will leak through. I use a soldiering iron to melt the holes or hammer a nail in several places. You want minimum of 3 holes. The amount depends on the size of the cap and bottle you are using. I usually make 5 holes. You then want to several strings (quantity should match the amount of holes he created in the lid) as long had the full height of the bottle. You want to thread the strings through the holes in the lid (1 string per hole). Cut the bottle in half about 1/3 down from the top (drinking rim). Add water to the bottom half of the bottle at a little past half full. Take the top half and screw the top on. You want to insure that the thread is extending 1/3 down the top half the lid and the rest extending out the opposite end. You now want to invert the top so that the cap is seated first into the bottom half of the bottle. Add soil to the top half of the bottle. The strings should be mixed throughout the soil (the other half of string should be emmersed in water). Now place the seeds into the top half of your planter. Water the soil. Label your planter.
Let your plant grow!
How it works: The string wicks the water to the top to keep the soil moist.
Tip: Never let the water come above the lid. The soil will become to moist and the situation can lead to mold. Once the initial water is used we put the seedlings on compost tea.
