Heaps of people ask me how to take clonesÖwhen to take clones...so I have done this little tutorial.
of cannabis can happen a few ways, as explained in Marijuana Botany, by
Robert C Clark, an older book but I think its one of the best and every
serious grower should have a copy. If you donít have a copyÖthen I
suggest you get one. Just Google Marijuana Botany
Propagation starts with a male and female plant, once the female has
received the pollen from the male the seeds will start to form and take
about 6-8 weeks to mature...these seeds can be planted and the life
cycle begins over...obviously the females are the ones we prize, but we
do need a male too. Once you have a pure female then we can think about
cloning or what is termed as Asexual Propagation
Clones can be
taken at any time of the plants life, but they usually take easier
while in vegetive stage, I think because the plant has higher levels of
nitrogen, its easier for them to take root, that could be a myth??
Clones do seem to take better while in vegetive stage.
clones you will need, a twin batten flouro, with grolux tubes, a
humidity crib and heat pad, clone cubes, perlite, a sterile knife, some
plastic cups, and some cloning gelÖoh also a bucket of clean water and
a glass of water.
The plastic cups can be bought from any supermarket.
Ok letís start...........
First of all letís get everything set up, this way the clones can go straight into the crib as they are doneÖ
Set up the cloning trays with the heat pads underneath. Fill with perlite, a nice layer about an inch thick is good.
Pour a little water into the tray, this creates the humidity.
Right thatís the cribs set up. Turn everything on, the light needs to be on 24/0.
Now letís get the clone cubes set upÖ
There are 2 size clone cubes; I have used the larger ones. Cut the cube into 8 equal parts, using a sterile knife.
Hereís the blocks all cut up.
are the cups, using your knife Cut small v's at the bottom, so water
can drain out, one either side should be enough. Fill the bottom with
some perlite, about 10-15mm.
the cubes so they make a nice snug fit into the cups...not too tight
but not too loose either. Leave about 10-15mm at the top for more
Once they are all done they are ready to soak.
use rain water, its better. Canít get it then any filtered water will
be fine. Fill up a bucket. You can have the water PH adjusted; I donít
think its necessaryÖ
Dip the cup into the water until it is completely soaked.
Drain off excess water.
Squeeze out excess water, until the cube is about %40 wet.
Place soaked cups on a clean towel.
they are all soaked you are ready to poke a small hole. If you have
used the smaller cubes then the hole should already be there, poke it
anyway just to open it up. Using the big cubes you will have to make
your own. Donít make them too big, they need to be a tight fit. I use a
Ok, all done. These are ready for cuttings.
Fill a glass with clean water.
This is so once the cutting has been taken it can be placed in the
water immediately. This stops air contamination.
Select a nice shoot for a cutting. It should have at least 3 nodes.
a sterile knife, cut the branch so that there is about 3cm below the
last node. Repeat until the glass is fullÖusually about 8 cuttings.
Set up a little station as I have done here. This way everything can be done as quickly as possible.
Dip the clone into the cloning gel, just below the last node. Donít get any on the bottom node, only on the stalk.
you can see the gel. Using the clone, drip some gel down the hole in
the rockwool, re-dip and then place into the rockwool.
Place the clone into the rockwool, make sure it is a nice firm fit
Fill the remainder of the cup with perlite and replace on the towel. Repeat until they are all done.
Place clones on the tray, making sure they are not going to fall over.
Try and keep the clones to the center of the tray. Ok, all done.
just a little spray with water and you are done. You can mix a %20
nutrient solution and use this as a foliar spray. I use worm liquid and
a salt free soda water, about 30ml per liter. If you have a soda stream
then use that with rainwater.
the lids on and let the humidity build up, leave the holes about half
open. Every day check that there is enough water in the trays and spray
once a day with the soda water.
you are all done, almost. You need to check these once a day, making
sure there is enough water in the trays to create humidity, also
spraying once a day with the worm liquid and soda water.
also make up a solution with the cloning gel, about 20ml per litre. I
water using a big syringe, making sure the mix does NOT touch anything
else. When you do this, squeeze out the excess water... about %40 wet
is what you want, any wetter and you risk getting stem rot. Watering
shouldnít be necessary for the first week, just keep the cubes about
%40 wet for that first week. Also rotate the clones every 3-4 days,
placing the outer clones to the inside, which is where most the heat is
from the heat pads.
You should start to see roots in about 2
weeks, usually takes up to 4 weeks before there are sufficient roots
for planting. I usually repot at the third week... but rooting rates
may vary so this is up to you.
Good luck on your endeavor and I hope this little tutorial has helped.
4 WEEKS LATER (35 days)
the clones have been repotted into little cups and have been under the
400 watter for almost 2 weeks, they need pruning so I decided to take
another set of cuttings....
I didnít take pics in between cuttings, kicking myself now, but I have taken 2 lots off cuttings of these.
under the 400 these girls have grown nicely and need to be pruned. Iíve
decided to take some cuttings. These clones are at 35 days.
you can see them re-potted; they have been under the 400 for almost 2
weeks and can be cloned. This is what I might just doÖ
There are a few tops to cut.
Here you can see the little cups Iíve repotted the clones in a bit better. These are ready to take some more cuttings.
56 days old, Iíve taken 2 lots of cuttings of these and I am about to
prune them back again. Under the 400 for another few days. Then into
the main room for flowering.
well thats all there is for this cloning guide... I hope I have been some assistance...
