Easy Plant Tissue Culture Clones
C
annabis growers have discovered the secrets that the horticul-
ture industry has known for decades, that plant tissue culture is
the most efficient method of producing pest-free clones. Dedicat-
ed mother plants are eliminated and new plants are generated
in jars or from their rooted plants thereof.
The secret to plant tissue culture is using sugar as an
energy source. The tiny cuttings absorb sugar, nutrients
and vitamins directly through their surface and grow
in a self-contained environment while hormones in the
media encourage branching and keep the new nodes
tight. A proper vessel will keep the plants small and
disease-free, saving time, light and money. Preserva-
tives should be added to the medium to reduce the
possibility of mold. The new branches and nodes can
become the sources of thousands of cuttings.
The following items should be included in a tissue
culture kit:
✔ ✔ Culture vessels with lids-glass or polypropylene
✔ ✔ 8 inch tweezers
✔ ✔ Scalpel or paring knife
✔ ✔ Shallow 8 inch plate for cutting
✔ ✔ Mason jar for washing plants
