## Product: Jiffy Seed Starting Mix
**Brand:** Jiffy

## Pros
- Effective when combined with worm castings or diluted fish/kelp oil.
- Can be used in outdoor soil mixes if adequately blended.
- Some users reported strong seedling growth and plants that appeared eager to grow.

## Cons
- Not suitable for delicate seeds like snapdragons, leading to a complete failure rate.
- Prone to compaction, which affects seed germination, especially for fine seeds.
- Poor water retention; initial watering often doesn't penetrate well.
- Requires soaking and mixing with perlite and vermiculite to improve moisture absorption.
- Approximately two-thirds of the bags have mold issues.
- Recent batches have shifted in quality, indicating poor seedling survival due to root rot.
- The peat moss used is hydrophobic, exacerbating moisture issues.
- Experiments showed it underperformed compared to other brands in germination.
- Users expressed strong dissatisfaction with changes in quality and reluctance to repurchase.

## Bottom Line

The Jiffy 12 qt. Organic Seed Starting Mix falls short for delicate seeds, struggles with mold, and has poor water retention. While it shows promise when amended with additional nutrients, these modifications reduce its cost-effectiveness. For those dealing with mold or water retention issues, exploring alternative seed starting mixes might be justified. We find it advisable to consider other products with a better track record for seedling success, especially if working with delicate seeds.
