If the video mentions yeast and sugar, it's likely referring to a common DIY fertilizer or plant growth booster that utilizes fermentation to release nutrients and stimulate microbial activity in the soil. Here's a general idea of how such a mixture works and a typical recipe:
Purpose:
Boosts soil microbial activity, releases CO₂, and provides nutrients that encourage vigorous plant growth and potentially improve yield.
Basic Recipe:
1 tablespoon active dry yeast
2 tablespoons sugar
1 liter (or quart) of warm water
Instructions:
Dissolve the sugar in warm water.
Add the yeast and stir well.
Let sit for 1–2 hours until the mixture becomes bubbly/active (fermentation starts).
Dilute the solution with 5–10 parts water (so if you started with 1 liter, dilute to 5–10 liters).
Water your plants with the solution, especially around the root zone.
Yeast helps stimulate beneficial microbial life in the soil.
Sugar feeds both the yeast and soil microbes.
Fermentation releases small amounts of CO₂, which can promote photosynthesis in a controlled environment.
It can improve nutrient uptake, especially in nutrient-poor soils.
Use this mixture no more than once every 2–4 weeks, as overuse can disrupt soil balance.
Apply to well-draining soil to avoid root rot.
Avoid using on plants sensitive to high microbial activity (like some herbs or succulents).
