Worm Castings on Coco Coir for Microgreens — Does It Improve Growth?
🧪 Can adding worm castings to coco coir improve microgreen growth? In this experiment, we compare plain coco coir against coco coir mixed with VermisTerra premium worm castings to see if this soil additive makes a noticeable difference. We've done a lot of hydroponic nutrient experiments on this channel, but this video marks our first dive into the world of soil additives for indoor growing — and the results were very interesting.
Here's what we tested:
✅ Coco coir only — no additives, water only
✅ Coco coir + VermisTerra worm castings — soil additive mixed into the medium
Here's what we cover:
✅ Coco coir vs. coco coir + worm castings — side-by-side comparison on microgreens
✅ How worm castings affect germination, growth, and overall crop quality
✅ Whether the added nutrients from worm castings make a visible difference
✅ Our first impressions of using soil additives for microgreens
✅ Why worm castings are a natural, organic way to enrich your grow medium
✅ What this experiment means for our future soil additive testing
Worm castings are a natural, nutrient-rich organic amendment that many soil growers swear by — but their use for microgreens specifically hasn't been widely tested. This experiment gives you real data on whether mixing worm castings into coco coir is worth the extra step and cost. The results gave us the push to continue testing soil additives in various ways, so expect more experiments in this category.
