GreenX How to's... How to Clone in Soil (w/pics)

    This is a basic guide of How to Clone in Soil, it is generally step-by-step and will hopefully be helpful to anyone who has never done this before and is wanting to give it a try.

    For more of my guides to come, simply search Titles only, keyword: GreenX How to's

    Step 1: Get some nice sharp scissors, secateurs or knife (here I'm using harvesting scissors), sterilize the blade(s) by wiping them with methylated spirits or other bacteria killing liquid.

    Step 2: Select the plants you wish to take clones from, here I'm cloning AK because they've been under fluros longer than I had intended and they're getting a little too tall and stretched, so I want to also reduce that height by topping them for the clones.
    Sorry some pictures are a little blurry.

    Step 3: Select the node you wish to cut to, angle the scissors about 45 degrees and make the cut about half a centimeter (0.5cm ... 0.2 inches) above the node you selected to cut to.

    Step 4: Once you've got all the clone you want to cut removed from the respective plants, it's time to prep them.

    Step 5: You may do these next steps with all the cuttings at once, or do one cutting at a time, it doesn't really matter.
    Take the clone(s) in front of you, isn't she pretty haha.

    Step 6: Cut any excess stem off about 0.5 cm below the bottom node, at a slight angle (45 degrees is always good).
    Try to make it a clean cut, as this is where the clones new roots will grow from.

    Step 7: Remove any lower leaves or side shoots and reduce the larger, remaining leaves a bit by cutting them in half. (This is to reduce transpiration so your clone won't dehydrate to quickly, whilst allowing enough leaf remaining to allow for photosynthesis once the clones new root system has established).

    Step 8: Now we've got all our little clones prepped for planting.

    Step 9: When cloning in soil, a good rooting hormone, although not necessary, is always helpful and definitely makes things easier.
    Here I am using Growth Technologies CLONEX

    Step 10: Pour a small blob of rooting hormone into the lid of the bottle (or other clean container), the reason for this is that after you've used rooting hormone, you want to throw it away, if you put it back into the bottle and any plants have had a bacterial infection it may get into your rooting hormone, contaminating it, and making it useless for future use. It's simply easier, and better to put a small blob in the lid, use it, wash the lid with warm water, then seal the bottle again.

    Step 11: Dip the base of the cutting (where you made the angled cut below the bottom node) into the rooting hormone so that the gel (powder or liquid for other forms of rooting hormone) completely covers the wound.

    [Step 12: Fill a pot or seedling tray with soil (seed raising mix is always a good choice), and make a hole in the center using anything that can make a good hole haha. Make sure the pot has good drainage holes so water won't sit in them with nowhere to go.

    Step 13: Place the cutting in the hole and lightly firm the soil around it using your fingers, add more soil if necessary. To firm the soil, just use your fingers to lightly press down on the soil all around the clone so that it becomes a bit more compact, be gentle, she's a young lady remember.
    Once again, sorry about the blur.

    Step 14: Using pH 7.0 water, water your newly planted clones so that the soil is well damp, but not sopping wet.

    Step 15: Place the clones under a light such as a fluro or a few CFL's and have them on a vegetative photoperiod, such as 18/6, 20/4 or 24/0, do not have a fan blowing directly on them, this is not good for them, however do make sure they get fresh air regularly. Sometimes it may be necessary to keep them under a humidity dome (if you notice them wilting a lot then a humidity dome may help), a humidity dome is basically a plastic cover that stops water from evaporating into the atmosphere, and instead it condenses on the plastic, dripping back down and raising the relative humidity (rH) under the dome, meaning the clones will transpire less, thus, losing less moisture from them, thus, they're less likely to wilt. A humidity dome is not always necessary.
    When using a humidity dome, it's important not to let water droplets sit on the leaves as they aren't likely to evaporate and can therefore cause problems like mold, fungus and other bacterial infections, if there's water sitting on the leaves, leave them uncovered for 10-20 minutes to give it a chance to dry a bit, the clones will love the fresh air anyway!

    Hope this helps some of you out their. If you're unsure of any of the terms I've used, hopefully my Glossary of Terms will help you out: Glossary of Terms


    GrowTech stays relevant.

    Very well written guide. I will try this out as soon as my mothers get big enough for it. +Rep for you!

    Cheers mate.

    maybe use a razor blade instead of pruning shears..
    other than that good job

    GreenphoeniX Well-Known Member

    They're actually harvesting scissors/shears for harvesting fruit haha.

    Anything sharp that can cut works... Any new grower will be far more inclined to use scissors than a razor blade... I've never used a razor blade for cloning in my entire life, I've never seen the point, as long as you can cut the stem and the blade is sterile, it'll work.

    What are the advantages of using a razor blade?

    weezer Well-Known Member

    i read that in ed rosenhaul book many years ago..
    it does not crush the stem and gives a cleaner cut..
    it is good that you point out to clean them ...
    years ago i order a bunch of different seeds from marc emery..
    i used the same blade to cut clone from 5 -6 varities ..
    most die because they got diase from each other..
    same with diping in same pile of rooting hormone:peace:

    its69 Well-Known Member

    this looks quite simple actually well written guide, can i buy clonex from b and q?

    GreenphoeniX Well-Known Member

    There you go people, if you don't want to risk crushing the stem, use a razor blade or very sharp knife. Remember to sterilize them first, and maybe even after every few cuttings if you're doing a lot at ones, same goes for changing to fresh rooting hormone every so often if you're doing a lot of cuttings.
    In my personal opinion you don't need to worry too mush about damaging the stem a little bit, damaging the stem can actually encourage rooting, but it's easier to just do things cleanly and lower the chances of bacterial infection :D

    I have no idea what b and q is, I guess that doesn't exist where I live... But I get it from my local growshop ... Growth Technologies has a website, maybe you can order it off there it you want, not sure though.

    if im running a hydro method i could do the same thing and just place in rockwool cubes right? what about putting the rockwool cubes into the soil so it is easier to move to the veg room once they root.

    GreenphoeniX Well-Known Member

    Yea you can just do it straight into rockwool mate. Although in my personal opinion I think when cloning for hydro purposes it's best to clone using a basic bubble cloner, give me a day or two and I can post a thread on how to make one if you like.
    It's relatively cheaps, the most expensive part is an air pump and stones if you don't already have any spare.

    Let me know if you're interested guys and if ya keen I'll make that thread and post the link.


    justsmoked Well-Known Member

    yeah id be interested to see how to do that. the clones im currently getting come rooted in rockwool and that is easy for me because i can just place them into my hydro setup and then they are good to go. Any method that is in rockwool or something that is easy to transplant into the hydro rocks is what i am looking for. thanks.

    Excellent pictures and write-up, and excellent clones!!

    Those clones look better then 90% of the clones at the dispensaries in southern ca.

    so how many clones did you take from each of the plants pictured?

    Sedition Well-Known Member

    Many thanks GreenX! I have seen many of your guides and they are all very helpful for a beginner like myself.

    justsmoked Well-Known Member

    yeah GreenX is the bomb.

    GreenphoeniX Well-Known Member

    Mate, I've been so f**kin' busy lately haven't had time to do a proper bubble cloner write up yet (but will do when when time's available), so for now I'll type up the info quickly and add a guide with pics later (man I'm hung ova haha)

    SO basically, you get a tub, or bucket, whatever, fill it till it's an inch or two from the top, put a couple air stones in it, connected to an air pump obviously, so that when they're turned on the water sends little droplets into the air as the bubbles hit the surface of the water and explode.
    Cover the tub with tinfoil (or something similar that's waterproof), then make holes in it which is where you insert the cuttings, (which are prepared the same as here: http://www.rollitup.org/general-marijuana-growing/102940-greenx-how-tos-how-clone.html, but going into tin foil instead of soil) so that there stems are suspended about an inch above the water, the exploding bubbles will splash water onto the stems, they'll obviously get plenty of air too, keep the air pump running 24/7, should root in about 2 weeks-ish. A humidity dome can be used but is rarely necessary because they hav plenty of access to air and water around the stems, and later roots. Transplant them when roots are developed enough, into whatever medium you're using. Really good for Hydroton (clay balls) because it's so easy to put in there, even though you will cause at least a little root damage at transplant, no big deal tho.

    Like I said, I'll write up a better guide, with pictures and things, when I get time, but hopefully the above info helps a few of you for now.

    yeah i feel you on the hung over today man, but nothin some green didnt help. im using the hydroton in my hydro setup now, is there any strategy similar i can do that i can using the small rockwool cubes?

    goober246 Active Member

    This is ona the best tutorials iv seen for cloning!
    thanks man

    GreenphoeniX Well-Known Member

    Ok. So as promised, here's that quick guide on how to make a Bubble-Cloner: http://www.rollitup.org/general-marijuana-growing/110683-greenx-how-tos-how-make.html
