One plant very difficult to clone- why ?

[oldog]

I have a Lemon Skunk mother that I have tried to clone in an aeroponic cloner(EZ cloner type) with 6.5 pH water ,no hormone, no fert, and also in top quality seedling soil mix with gel and powder cloning chemicals, but they either die or produce one root after 3 weeks while cuttings from other plants have 8 roots or so after 10 days. Are some species just difficult to root or am I doing something wrong ?
Thanks

some are difficult to root....

you just nailed it, some just dont like to clone. i have air-layered clones that wont take in other cloning methods, that might be helpful to try
HA

6.5 is alittle high ,but yes some strains are harder than others.Never mind the fact that some breeders have been experimenting so there clones wont take.Theres a thread on that around here somwhere.

Really? I could see making them sterile so you can't make your own seeds...but to prevent cloning? How? Got a link?

I just cloned LS in 5 days. Change out your water after a ew days in the ez with fresh COLD water. Stuff starts to build up on the bottom.

Thanks to all. I searched my Cervantes book and see he says that
older branch tips clone better and that daily, thorough leaching of the mother of difficult to clone plants with water for a week prior to taking cuttings helps. Will give that a try next time. Will try changing res water for the current ones.

You obviously have cloning down if your others are surviving. Just remember that all plant tips are viable. more so those on the top for faster rooting. Remember to cut 3 nodes under your top cluster while cutting a 1/4inch under the the bottom node. You need that bottom node because there are active auxin's there. Good luck friend.

I just saw a post saying that the water temp should be about 70° - 75° F.
Mine was about 83°F which is said to be the cause of the 'mushy stem' that I got . Question is, how to simply and cheaply lower the temp ? Can I just chuck a few ice cubes in there 4 times a day ?

Some are hard. try all the other different methods. soil, rockwool, peat, rapidrooter.. whatever. I found the plugs to work well for some strains when they wouldn't work in my bubbler.

No I dont have a link ,wish I did though.I just stumbled across it searching cloning here.I dont know how much if any truth was there ,but it made sense on a buisness point of veiw

 

[HempAlchemist]

in potato farming, esp russels, the potatos are sprayed with a chemical that slows down the growth of the "eye". it is quite possible that there is a chemical that you could spray on a plant that would slow the rooting process in clones.

Hey guys the 6 in the middle are LS. 7 days old these are from GHS so I don't know if thats a factor but I just threw it in there. Out of the 6 some clone faster then others but they do clone easily bro. The mother plant these came from was munching on 1400PPM veg mix too.

I would leave your LS's in there but draw up a new batch of clones just in case. Replace the water as well bro and wipe everything down.

 

[has_some_sinse]

I would say the problem is they are GHS...but if u think its worthwhile, too much residual nitrogen wont allow roots to grow, also less direct or intense light help, and I foliar feed with liquid karma 5ml/gal. N is bad and P & K are good in cloning.
May be bacteria intolerant strain, in that case hygrozyme will keep you sterile, also use city tap water..the chlorine and chloromine are a good thing in an EZcloner.. I have a ez60...but its a pain in the ass to keep the bacteria under control, spent more in products fixing the inherent problems with EZ than I did on the EZ....try dixie cups and foxfarm...its my bulletproof, if I absolutely cant tolerate to risk something super rare...like my ssh male or C99 Grail girls.

SDGuy: Do you use any Clonex /hormones/Dyna Grow etc. or just plain tap water? Some say to soak the cutting in gel for an hour, others say put some stimulant in the water res. I was not using anything -just water that had been aerated for two days and pH'd to 6.5. I think I'll go lower next time.

I used DynaGro Rooting gel (12 bucks) this time instead of the EZ Clone solution. sterilize your cloner! (Remove the front cover from the pump and clean the grill. Bacteria tends to start colonizing there. Also remove the ring inside and clean the impeller magnet. Make sure there is no debris or goo to colonize bacteria there either.) - Then run HOT water with a few cups of clorox and run for 30 minutes. Drain and refill with HOT water again and run for 30 minutes no clorox. Now drain and refill with COLD water and let run for 12 hours prior to adding cuttings. Do not open the dome in this time. The heat and humidity is just right - just dip the cutting in rooting gel making sure you cover all the wounds just a few seconds and place in the cloner. All while the cloner is running. No need to unplug and do not worry about it washing off.

That right there I've done twice in a row and twice in a row I've had 99.9 percent.

Do try and replace the water every 2 days. If you don't have a chiller like me then the least you can do is remove any bad bacteria from colonizing and replace it with fresh water. This way you're in control of the balance of things. You see bad bacteria is always present. It's only when the bad bacteria colonize into larger masses than your good bacteria that you start to see stuff happen. Replace the water often and you can control that balance. Or get a chiller and you're set. I don't mind the extra work and do use your chlorinated tap. The chlorine does not affect my roots and assists in killing bacteria. Shit I'm rambling like a speed box. Just realized it but I'm really medicated so I'm sorry but I hope the OP tries this too.

EDIT:
Just 1 last thing.. I've noticed that the threads from the misters tear into the manifold if you screw it on too hard. This may cause a loss of pressure to the affected sprayer because water is also rushing through the sides of the sprayer head instead of the center nozzle. Depending on how many sprayer heads are loose this can cause an uneven rooting time for cuttings. You can either use plumbers tape to seal the threads or raise your waterline just under the spray nozzle but over the threads. Just make the water level really high but don't drown the nozzle.

SDG: Thanks for all that info. I read up the EWC info in your current
grow and will try that as I just got some to use as a soil ammendment. (Im done with hydro after 2 failures)

Can you give me more info on how to 'pinch' and shorten plants
that you mentioned in your grow failure with the one that turned out to be male. A link ? I have a few young very sativa Tai Hazes that I was going to dump but after killing all my seeds with V. wilt, I will grow them out, but I want to try to make them more bushy and shorter. The plants are now about 12" tall and have a coconut tree look. They are in their first week of 12/12. I'm worried that if I cut the top there won't be enough leaves for it to grow. Will it sprout from the bare trunk ?

Hi Oldog,
Sure thing bro I'd be more than happy to help. Do you have a thread open? Shoot me the link and we'll speak about it there. I don't want to throw the OP's thread off topic. If you don't have a thread get one started but send me a link to it
