What is cloning? |
|

Cloning is a form of plant propagation
that has been around for a very long time. It's basically taking a
growing portion of a plant - a stem with some leaves attached, and
helping it to become a brand new plant that is genetically identical
to the plant from which the clone was taken. This is often easy to
do because plants often clone themselves in nature. It's called asexual
reproducation. The methods currently used today include taking cuttings,
layering, division, grafting, budding and tissue culture. Gardeners
often trade cuttings and divisions as a way of sharing plants with
their friends. |

Can all plants be cloned? |
|
| |
Most plants can be cloned, although it takes different methods
to do so. Some plants will reproduce readily while others take a
considerable amount of time and care.The methods currently used
to day include taking cuttings, layering, division, grafting, budding
and tissue culture. The kind of cloning used by growers of pepper
plants and tomato plants is to take cuttings.

How do I take cuttings? |
|
| |
The biggest requirement for taking clones is a healthy parent,
or stock plant. A parent plant should be in excellent health and
should posess the characteristics wished for in the new plants.
It should be at least two months old and it should still be in the
stages of vegetative growth. Besides that you need
- Extremely sharp, sterile razor blade for cutting off leaves
and foliage
- Rooting hormone or solution
- A cup of lukewarm water
- A tray with a clear plastic dome
- some form of growing media, such as a sheet of oasis cubes
- Spray bottle
Propagation -Stem Cuttings use 6" humidity dome
18 hours light/day
rooting hormones-Wilson roots, Stim Roots, Willow water
remove largest leaves to avoid wilting
remove tent permanently after 10 days
damping off fungi-better air circulation, and/or treat with damp
off
browning leaf tips-to much nutrient.
At least one node (the point on a stem where leaves are attached
and buds form) should be below the media surface.

How do I start seeds? |
|

Rockwool is the most popular medium for hydroponic germination
of seeds. Loose, or granulated rockwool can be placed in a standard
plastic starting tray. Seeds are spread evenly spaced on top of
the medium. The seeds are covered with a thin layer of rockwool
or perlite and the tray is covered to prevent moisture loss.
The loose rockwool makes it easy for thinning and separating seedlings
to transplant. An alternative is one inch rockwool starting cubes.
A flat block containing 98 detachable cubes fits into a standard
propagation tray. The rockwool is soaked and pH balanced and one
seed is placed into a 1/4 " deep hole provided in the centre
of each cube. The seeds are then covered with a thin layer of perlite
or vermiculite and the lid is placed on the tray. Once the seeds
have sprouted, the cubes are easily broken off and placed into larger
growing cubes or other aggregate.
Sow very small seeds by sprinkling on top of the medium and pressing
in. Use a fine mist of water to gently wash seed into the growing
medium. Sow medium-size and larger seed in rows 1 to 2 inches apart,
and 1/8 to 1/4 inches deep. If no depth is specified on the seed
packet, use the general rule of planting the seed at a depth twice
the diameter of the seed.
When sowing in a tray or flat, sowing in rows is preferred over
scattering seed. This method provides better air circulation than
scattering of seed. When seedlings are crowded, they may become
tall and spindly. To avoid the need to transplant seedlings from
a seed flat to pots, you may sow seeds directly into small rockwool
cubes. . Plant two or three seeds per cell or pot. When they germinate,
remove the two less vigorous seedlings.
You may use a variety of growing mediums to start seeds, but whatever
you use, you'll want to keep it moist, not wet. You can do this
by keeping the container inside of a plastic bag, or use a clear
plastic dome over your tray. The idea is to keep the moisture in,
but allow air exchange, so be sure to leave a little air opening.
If you do this correctly, your seeds should not require any further
watering until germination. Provide proper light and temperature
conditions.
Once seedlings germinate, remove the container from the plastic
bag. Place the container in a location that has high light intensity
and cooler temperatures.

What kind of light should I use for
indoor cloning and seed starting? |
|
| |
Seedlings and clones require bright light for healthy growth. Most
growers use special spectrum fluorescent lights for these early
stages of plant growth. These can burn in the same kind of fixture
you find at the hardware store, but they provide more lumens of
the correct growing spectrum than do ordinary hardware store bulbs.
They are slightly more expensive, but they will result in a much
helathier start for your plants. Click

Most clones and seedlings benefit from 16 to 18 hours of light.

What temperature should I keep my clones
at? |
|
| |
Keep seedlings in a well-ventilated, cool location. The temperatures
should be 55 to 60 degrees F at night and 65 to 70 degrees F during
the day. These temperatures encourage compact, bushy, vigorous growth
while minimizing disease.
