Introduction: Hydroponic Reusable Seed Sprouter
Spring is here (near?), which means that it's time to grow some peppers. Last year it was habaneros. This year, it will be bell peppers. This instructable shows how to make a reusable hydroponic (dirt-free) sprouter for starting seeds. When finish, just squeeze the sponge dry and store for future use.
Only a smaller (or several small) container is required. It should have a soft lid. Film canisters work great if you can find them. I found mine at a flea market.

Step 1: Modify the Lid
- A hole was cut into the canister lid using a utility knife.
- A coat hanger was used to hold the aluminum window screen mesh apart on the clothing iron.
- The lid was pressed into the clothing iron to meld the plastic.
- When removed, the plastic was fused to the lid.
- The excess window screen material was cut.
Step 2: Assemble the Sprouter
To sprout the seeds, the following steps are necessary:
- Put seeds into sprouter.
- Close lid.
- Fill with water so that it overflows.
- Let it sit overnight (helps water penetrate / soften the shell).
- Drain water.
- Once every day thereafter, fill with water and drain (prevents molding, removes bacteria, etc.)
Step 3: Results
- 29 / 67 - Duds (Failure to Sprout)
- 6 / 67 - Dying (Had Black, Too Dry or Rotting)
- 10 / 67 - Long (Too Long, Some Black Tips)
- 15/67 - Medium (Medium Sprout, No Black Tips)
- 7/67 - Short (Short Sprout, No Black Tips)
Step 4: Plant Sprouts
- Film canisters as containers.
- Pencil tip as depth of seed.
- Nasal rinse to water.
