clones won't root in 24 hour light

I don't think it's the light cycle. I think you may be using too much light. I've only really had luck with dim light cloning. I use a single 13W flouro for a 50 cell standard rapid rooter tray. I use 20/4 lighting too. But I've also used 24 hour lighting with success.

To much light, raise your lights they need to concentrate on root making not photosythesis and vegging.
 
I have better/faster results cloning with little to no light at all for the first few days then introducing them slowly. Generally i just throw them in the corner of the veg room with a trash bag on top of the humidome until they look like they want light.

I saw a study somewhere online that shows plants actually grow faster when they are allowed to rest daily versus 24/0 so personally i try to stick to a 18/6 20/4 veg cycle, it will also save you some dollars on that power bill.

Thanks for the help everybody. I got the problem solved. there was a heating duct under the floor where the cloner is and every time the heat kicked on it heats up the water and caused root rot.

some classic water cloners who stick cuttings in a glass of water for a few weeks say 12/12 gives the best results. The fact that roots grow in the dark period is t2o fold as they use transparent containers...inhibiting root growth

i use rapid rooters and clear cups, 24/0 lighting. roots dont need darkness to grow.

The far right is the finished cloning container, it is 3 cups total.

Yeah, I usually go 24hrs darkness then to the 18/6, or 24hrs. Haven't noticed a difference either way, but the do seem to like a little light break after the stress of cloning.

ROOTS DO NEED DARKNESS TO GROW. thats what your medium provides among other things. Studies have shown root growth is accelerated at night even if their nedd foor water is lower. A dark period may have helped as he is using aero cloners and light may be getting into the roots. The 24/7 lioght could also cause the temperature to rise too much
 
First, don't let anyone tell you that rockwool is hard to root in. Rockwool has to be soaked in water that is ph'ed at 5.5, longer is a little better but 20 min. works. I've been 100% with rockwool for a long time. Second, to much light is a bad thing low watt/heat flouro's work like a charm. Third, 24 on is overkill 20/4 or 18/6 are ideal. Fourth, roots need darkness to thrive.

I use 24/7 light. Veg room is on all the time & clones turn out great. You don't have to do it this way but it does work. :)

You are retarded. This is a CLEAR EZCLONER.

I figured the 10+ people saying 24/0 was possible would be enough, but I guess not. Even your argument that the rapid rooters provide darkness to the roots is complete bullshit.
Where is the necessary DARKNESS with the clear ez cloner?

Rather than spouting some bullshit you read somewhere, why not just keep your trap shut on things you are not 100% sure about?

I have made clones for two decades+, I use 24 hours, with sunlight supplemented with florescent tubes or if sodium lamps a bit higher up from the clones, I have used ebb & flow systems with rockwool, and 7-11 peat plugs on a damp sand table heated from below. I get over 95% with all methods unless the heat gets to high in summer in my greenhouse, then I use florescents indoors. I have made thousands, with no problems under 24 hours. With and without rooting powder or gels.

I use 24 hour low wattage(mostly cool flouro) lighting,under-heating if cool temps and rockwool cubes usually,jiffy plugs occasionally,both work fine...Loose Perlite /vermiculite or bubble/aero-cloning can be quicker but I am happy as long as they are rooting well in 2 weeks or so anyway. Plain potting soil in a cup and just placing in glass of water near window with no powders or gels have worked fine tho' too to be honest...In parts of Africa they just chop a big branch off and stick it in the ground,(sometimes with a clear bag or wrap on for a week or 2) Its not Rocket-science..Lol!

I tried cloning in 24 hour light and no luck twice. On the third I switched over to 18/6 hours light and had 16 out of 20 root. Do clones need darkness to root?


Where in the natural world is there 24 hours of light and plants living there?

Replicate the real world's light cycle and your plants will thanks you.

Did you have success with a bubble cloner with no air stone/wand

I found open lines too noisy and the bubbles violent enough to cause lid leaks. Airstones provide not only stealth but, bars or flat discs provide more even turbulence across the surface so all cubes/cuts are more equally sprayed.

Where in the natural world do X-acto blades mystically hover over plants, cutting off tips at a 45º angle and then telekinetically transport them into bubblers?

I use 24/7 lighting when rooting clones and always get good results. I do them in batches of twelve, never get less than ten and usually get twelve. I've had mothers living for years under pretty much constant lighting, and really thriving.

I've not seen anything to support the idea that plants need to rest in the dark regularly.

Electronic ballasts for Fluorescent lights will actually last longer.... when they're run 24/0.

I do all my cloning under 24/0 lighting. :D
