Step 2. Seed Sowing
If using OPCOM Farm seed capsules:
1. With completely dry hands, take out seed capsules from capsule bottle.
2. Insert seed capsules vertically halfway into the middle of each cross-opening in the
seedling sponge.
3. Put any unused capsules back in bottle and store in the refrigerator immediately.
If using non OPCOM Farm seeds:
Insert 3-4 seeds into the middle of each cross-opening of each sponge. The seeds should be placed
just below the surface of sponge.
Step 3.
After 30 minutes, remove the top half of the seed capsules with tweezers. The bottom half will have
dissolved into the sponge, depositing the seeds in the perfect location for growing.
NOTE: If you don't remove the seed capsule tops, they may inhibit sprouting rate.
Press and open

Make sure cross-opening at the top
of the sponge is facing up.
