Summary of "Compost vs. Fertilizer: I TESTED growing Peppers & Tomatoes with both - here are the results!"

Experimental Setup

Environment A:
- 100% sterile store-bought seedling mix (Promix).
- No additional nutrients or fertilization.
- Hypothesis: Plants will struggle due to lack of nutrition.
Environment B:
- 50% Promix and 50% compost.
- Incorporates organic matter rich in nutrients and microbes.
- Hypothesis: Plants will grow significantly better than Environment A.
Environment C:
- Same as Environment B (50% Promix and 50% compost).
- Added one handful of worm castings and one tablespoon of 444 organic fertilizer in each transplant hole.
- Hypothesis: Plants will grow even better due to increased nutrients and microbial life at the root zone.

Results

Environment A (100% Promix):
- Peppers yielded only 4 fruits; plants appeared unhealthy and struggled.
- Tomatoes yielded 67 fruits; better than expected but still limited due to lack of nutrients.
Environment B (50% Promix, 50% compost):
- Peppers yielded 12 fruits (300% increase compared to Environment A); plants were taller and healthier but not thriving.
- Tomatoes yielded 74 fruits; better growth than Environment A but not as significant as with Peppers.
Environment C (50% Promix, 50% compost, plus worm castings and organic fertilizer):
- Peppers yielded 38 fruits, with healthy foliage and many flowers indicating further growth potential.
- Tomatoes yielded 94 fruits (32% increase over Environment B); plants were productive despite appearing shorter due to heavy fruit load.

Key Takeaways

The addition of compost significantly improved plant growth and yield.
The combination of compost, worm castings, and organic fertilizer led to the best results, indicating the importance of organic matter and nutrients in plant health.
The presenter plans to continue using compost and organic fertilizers in future gardening endeavors.
