How long for cuttings to root cannabis

Use the misting setting for all of this. After misting, place the dome on the cloning tray. All of the water you sprayed ensures a high humidity inside the dome, which is exactly the environment clones need.

Whatever type of grow light you are using should go directly above the dome. If you are using a more powerful LED or a metal halide bulb, leave 2 or more feet of distance between the light and the dome. A dimmable LED grow light is great for this situation, since you can dial down the intensity, which also saves on power costs. You should mist the clones and the inside of the dome twice a day, every day. Ideal times are in the morning and in the evening.

The best way to get them is to grow roots, so we are encouraging that. On the first two days, just continue misting twice daily maybe even 3 or 4 times on the first day, if necessary. Keep the vents closed at all times. On the third day with the first day being the day you took the clones , open the vents and leave them open. This lets moisture escape, which may seem like a bad thing, but will actually help encourage rooting.

The lack of moisture dries out the peat pellets. On the 3rd day, there will already by the beginnings of roots sprouting inside them stem and the lack of readily available moisture encourages them to grow more quickly to find a source of moisture. On the 5th day, check to pellets to see if they are dry.

If they are, add about 2 cups of water half a liter. Add the water to the cloning tray, letting it fill the grooves. Do not add the water directly to the peat pellets. Adding water to the pellets makes it too easy for the plants to get water. We want them to have to reach down to the cloning tray to get water, because the way they do that is by growing roots downward. It is another way to speed up the formation of roots. On the 6th day, you want to close the vents again.

By now you should be seeing some roots coming out of the peat pellets for some of the clones. Now that the roots have begun to show, they need extreme humidity to encourage further growth. On the 8th day, add another 2 cups of water to the cloning tray. This time, infuse the water with a minimal amount of grow nutrients. Go ahead and remove the dome so that the clones can adjust to the normal environment. They should all have strong root growth, which means you can transplant them to their next home in a small grow tent or a large one.

Whats the consensus, How long is too long? We have had them take up to a month with purple strains not sure if it is normal or not. I say if they are green and health then keep waiting. Could light be stopping the roots from showing? Just a thought I have had a few times. O do your clones have new growth? I have had that happen too. COuld not see any roots but got new growth so I planted it in soil and it took off in a couple days.

I find that after a week they will remain turgid without a dome even when they have no roots, this is when you can start letting them dry out a little.

I guess they've rooted now. Hash Active Member. Clones take 2 weeks to root, roots will be there after a week but ive found removing them for the propogater after only a week slows their overall growth.

My last two sets of cuttings, placed into oasis cubes, have failed to root. After 15days, I started inspecting them and found the bottom of the cuttings to be white and deformed, like a little ball on the end. I use new razor blade with each plant, cut at a 45 degree angle under water, dip in clonex, and place in a pre-moistioned Oasis cube. All are then placed under a humidity dome and then under a 4 foot twin bulb T8 at 6 cycle.

What I do not understand is I have had great success with this exact same procedure??? What am I doing wrong? StoneyCt New Member. Thank you all for the information, My clone room is a constant 72 degrees, with humidity at around percent in the room. My first two runs were done exactly the same and they popped at days.

I pour out the clonex into a small container and discard what i do not use. The mothers are all healthy. Maybe I am expecting them to pop to soon, and just got lucky with the first two runs? RandyL New Member. I cut some clones a month and a half ago for my second generation of plants, and they took a good 15 days to show enough roots to plant them.

A couple actually had roots growing up out the TOP of the cube, as it was the easiest way out of the rockwool! I used the Clonex gel. I dipped each stem in the gel, and left a pretty heavy layer of Clonex on the stem when I put it in the rockwool.

All is good now, though. I learned from that. Slowpuffer Well-Known Member. I don't know, maybe the strain trainwreck is just hard to clone. But that's only a guess!! I have cloned different phenos of white widow, and some definately clone easier than others!! Jasonlee New Member. StoneyCt said:. What happens is when you dip your clone into the gel, it "activates" the gel, rendering in usless, after a few hours.. Always seperate or pour out the gel onto a paper plate or something Dont reuse or return unused gel.

Once you dipped the gel is active and after a few hours is no good A fluorescent lighting system is more than enough for a cloning tray or aeroponic clone machine. There have been many debates over red versus blue light and how each affects rooting, but I have had equal success with all kinds of light spectrums. One thing is certain—a grower does not need intense light for successful cloning. In fact, light energy that is too intense will hinder the process. Growers can get good results with an or hour lights-on period.

I prefer a hour lights-on period because it makes maintaining a consistent temperature easier. Successful cloning is largely determined by environmental conditions. As they are not yet established plants, clones require environmental conditions that differ from the other plants in an indoor garden.

To rectify this problem, many gardeners will create a specific room or area for clones where the environmental conditions can be kept in check. All indoor garden plants thrive in consistent environmental conditions and no plant illustrates this better than a clone.

A seedling heat mat may be the best tool to use to keep clones at a consistent temperature. For ultimate control, a thermostat can be connected to the heat mat and the desired temperature can be selected by the user. Humidity is another environmental factor that affects clones.

This high humidity is one of the factors that will stop the clone from completely wilting over because it is able to obtain some moisture from the surrounding air. A propagation dome is a great way for growers to keep a microclimate around clones and maintain a high level of humidity and a consistent temperature.

After the first few days, clones can slowly be acclimated to lower humidity. This can easily be done with many of the propagation domes, which include ventilation ports that can be opened or closed and are available through local hydroponics retailers.

By slightly cracking the ports more and more each day, a grower can slowly acclimate clones to the ambient humidity. If using a make-shift dome or a dome without ventilation ports, the dome can simply be removed for increased periods of time each day until clones have become acclimated.

A good starting point would be 10 to 15 minutes the first day and then increased by that amount each day after. Clones can be acclimated to lower temperatures as well, but it is usually best to do this after the first signs of rooting have appeared.

After seven to 10 days, clones usually begin to show roots. Once clones are rooted and acclimated to the ambient humidity and temperature, they can be treated as vegetative plants. Clones can be transplanted into the desired medium and fed a slightly diluted vegetative fertilizer. It is a good idea to acclimate freshly rooted. A grower can raise the lights for a few days until the plants start to reach for it, and then incrementally lower the lights to the desired level.

Scientist cutting plant tissue culture in petri dish. A more scientific approach to cloning that has recently made headway in the hobbyist market is tissue culture cloning. Tissue culture allows gardeners to make clones from plant cells or tissue. Tissue culture cloning allows the gardener to grow a plant in a petri dish from the tiniest slice of plant tissue. The biggest advantage of this process is that any pathogens, diseases or pests infecting the donor plant will not be transferred to clones.

Tissue culture also helps gardeners preserve rare and endangered species , or rescue embryos in distantly related cross-pollinated species. The biggest disadvantage of tissue culture cloning is that it is an involved process that requires special equipment. For most hobbyists, standard cloning is a much more practical application. In the end, cloning is a simple way any gardener can replicate the best qualities found in their indoor garden.
