Seed-Starting Grow Sponge Refills, 20 or 40 Pieces

Start a fresh planting cycle with replacement grow sponges for a compatible seed-pod growing system.

• ✅ Refresh used pods - replace the sponge for a new sowing cycle.
• ✅ Support seed placement - the sponge provides a medium for starting seedlings.
• ✅ Choose your refill quantity - packs of 20 or 40 suit different planting plans.

Keep Your Seed-Starting Setup in Use

Replacement sponges let you reuse a suitable growing setup without replacing the entire system. Plan a few sowings at a time or keep refills available for successive batches.

Check sponge dimensions against your pod holder before ordering. Seeds, holders, nutrients and the growing system are separate unless expressly included in the selected package.
