Production of mealworms is extreemly sustainable. Mealworms don´t drink water, they barely emmerge CO2, they eat only wastes and they don´t generate any waste themselves.
Frass is nice to work with. It doesn´t smell and it doesn´t make dust.
Frass is 100% organic and absorbed by the plant very slowly. Growing on Frass makes the plant parts stronger and the color more brilliant. The breakdown of Frass in the soil is done by the micro organisms over time, that´s why Frass doesn´t burn the plants.
In Frass you have Chitin, it´s mostly a component in the exo scelleton. When the plant detects the Chitin it will presume there is attack from insects and it will naturally boosts it´s immune system against pest attacks.
Frass is recommended for all house, pot plants, balconies, patioes and flower gardens.
Dig a small hole in the soil near the plant with the bamboo spoon, place a spoonfull Frass there. Cover and water as usual.
