The secret to plant tissue culture is using sugar as an energy source, instead of bright light. The tiny cuttings absorb sugar, nutrients, and hormones directly through their surface.
The plants grow in the self-contained environment while hormones in the media encourage branching and new plant production. The vessels keep the plants small, saving time, light, and money.
Preservatives have been added to the medium to reduce the possibility of mold. The new branches and nodes are the foundation of the Microclone grow room and sources of thousands of cuttings.
