The present application relates to a system for providing nutrients to plantlets, the system comprising: a water controlling agent, an organic waste material, a seed germination enhancer, a binding material. The water controlling agent may be a super absorbent polymer. The organic waste material may be worm casting. The seed germination enhancer may be selected from a group consisting of GA3, GA 4+7, and a combination thereof. The ratio of the water controlling agent to the organic waste material may be between about 1:1 and about 1:6.

Primary leachate is used as a plant growth stimulant. A fermentation medium is fermented with a microbial culture in a bioreactor to produce a primary leachate comprising microorganisms derived from the microbial culture and/or naturally occurring microorganisms. The primary leachate is isolated from the bioreactor, diluted with water, and used to irrigate plants to reduce bacterial diversity and stimulate beneficial microorganisms in the rhizosphere around the plants. The fermentation medium may be organic waste, preferably food waste. A secondary leachate may also be used as a plant growth stimulant. The primary leachate is used to culture black soldier fly larvae with a substrate in a secondary processing bioreactor under suboptimal culture conditions, thereby producing secondary leachate. Melanin is extracted therefrom by acid precipitation. The secondary leachate is then diluted with water and used to irrigate plants, reducing bacterial diversity and stimulating beneficial microorganisms in the rhizosphere around the plants.
