Growing clones in a cup of water

    Any OGs around to give some advice on growing clones in a cup of water? In trying to grow 6 clones in separate solo cups with tap water (there are definitely better ways to do this but heard that it can be done in water). The clones were healthy and good sized, and they're all still doing well and seem to even be growing (one of the clones leaves are yellowing slightly) however it's been 8-9 days and they're still not showing any visible roots.

    Growing conditions: Grow tent with 200W led lights giving approx 150-250 ppfd (18 hours on 6 hours off). Temperature fluctuates between 15-25 degrees celsius.

    Is there something I'm doing wrong using the cup of water method or do I just need to wait a bit longer? Any help/advice would be much appreciated, if I can even turn one of these into a plant that would be amazing!

    If my current clones don't work out is it possible to take clones from the mother plant after it's already gone through a flowering cycle? I'm planning on trying to reveg the mother plant after flowering, would I be able to take clones from that?

    I don't mind if it takes a while, if it works I'll be happy :)

    My wife takes cuttings and puts them in vases to decorate around the house. Some have lasted as long as 4 or 5 weeks. Rarely do they get roots. The rare one that does get roots flops shortly after. Roots like air. Once they pop, the cuttings might not be too happy with their anaerobic environment.

    I kept these in this setup for about two weeks with very little evidence of roots developing but committed them to soil anyway and still await the confirmation of the success or failure of the process.

    Put an air stone in the water?

    I wouldn't count on them rooting in water. I once got a branch to root by using it as mulch, doesn't mean it will work for everybody.

    What does seem to work for almost everybody is rooting plugs with clonex in a dome. The dome can be as simple as a solo cup with a ziplock bag over the top, and the clonex can be substituted for any other rooting hormone or even aloe vera.

    If the clones are tall enough, you can recut them and try again with a more reliable method.

    How much air do they need? Would you recommend that I take them out of water for a few hours every day then put them back in? Currently I've been taking them out of the water once or twice a day for 10-15 seconds just to inspect the root sites.

    you should replace the water multiple times a day and you can add a spoonful of activated carbon to the bottom of the glass to keep the water clean. it may not work now as you already had them in the glass for long a long time but you can try it.

    taking clones after revegging is ok and you can take clones from a flowering plant too but your success rate will be low. as for reveg its a tricky process and not all plants succesfully reveg after harvest and it takes way longer than 2 weeks.

    having said all that i think its best to get a dome and a heat mat and use coco or perlite and be extremely sterile with everything. they should root much better in a proper setup.

    ps: bubble cloners havent worked out for me i always get algae

    Bet that would actually work

    In case anyone is following this thread I thought I'd post an update. It's been 12 days now and 3/4 out of the 6 clones have started forming little white bumps, is this the start of root development? The bumps started to appear 2-3 days ago and still no roots yet. I've been changing the water every 1-2 days.

    And here are all the clones. As you can see the fan leaves on one of the clones are completely yellow and a few of the other clones have started to develop small patches of yellow, I'll remove the yellow leaves once I plant (if it develops roots) just leaving them on so the fan leaves hold the clone up out of the water.

    I do my clones in 1 qt glass tomato sauce jars painted black WITH FOAM TOPS, to keep the light out & they will root to app 4-6" in 2 weeks. Ph correct water as usual. Roots or not they have all grown once in soil, SO FAR. Right or wrong??? I'm happy.

    I've heard that using see-through plastic/glass roots even faster which confuses me since I would assume that roots don't like light haha

    That's what I figured but I'm BSC.

    Hahahah nah you're being logical, roots develop in darkness, makes total sense that you'd want to keep them dark when trying to root a clone. But idk fuck I might do a test next time using different methods to see what works best & fastest
