Had some problems guys

I took a few more clones from some plants 3 weeks into flower (that wasw 9 days ago).. Of the 4, 1 is already gone, 1 is pretty much gone and the other 2 are on there way out at least.. Been in propagator, lots of moister/water and heat underneath from 5W matt..

The first that died I noticed the stem become very weak almost hollow then just flopped over! They are all going that way now and today the one that looked the healthiest went floppy/mushy in the middle and has now bent over.. All the leave are dropping and shivelling up..

I am almost certain they are gone but I have just waked them under a 125W fluro as a last trump card type deal.. Will see the effect tomorrow All in all just wanted to hear from people what went wrong so that it doesnt happen again..??

Used clonex gel in rockwool.. The only thing to mention is they were sat in water for 2-3 hours before I could get them into the rockwool (Submersed in water so no air bubbles, and used stanly knife to make sure diaganol cut and stripped the skin off to expose to the clonex..

The 2 that dont look so good:

Hey mate, it sounds like they have got stem rot, if they have been kept to moist around the stem this can happen

[MrSparkles]

The pretty much dead already one..


And the one that already went to heaven and I removed it from the rockwool.. guess there is no trusting the rockwool anymore either:


As you can see the cutting has shrivelled up to a mushy fraction of the size it was.. stem is completly flacid?!?

Oh and yes that is a piece of string attached there.. when the stem first went flacid at the bottom I tried supporting it.. Didnt work the mushyness just took over the whole cutting...

Sounds like they got too wet/humid and got stem rot.The bottom heat may not have helped them. Also it is better to take clones while the doner plant is still in veg, once you have your environment right, you should be able to take them from a plant 3weeks in with more success.

Moisten the compost, spray the prop and just leave them alone, it can take up to 4weeks at the most but left alone they usually all take for me.

I thought they looked like root riots?? Sorry if it's not my eyes must be going to many bongs cheezehead

Using a 0.03% solution of hydrogen poroxside to steralise the rockwool and helps against stem rot or damping off but the main solution is let the top of your rockwool dry out before watering again. Root Riots are an excellent alternative to using Rockwool.

All the best mate

Thanks Greenfloyd and Pots..

Think your right Greenfloyd, it kept giving them water, obviously to much.. Annoyingly I did take cones during veg and 10/10 took fine



Just wanted to see if I could do it from flowering plants.. kept them in Rockwool this time but last time they where in rockwool/in soil/in pots.. This might give a more forging environment maybe?

Appologies they are rootriots.. me being a twat i thought they were the same thing

[Floyd]

no worries man.

Lesson learned, I've been there myself with it

Edit: To your question, having the root riot in soil doesn't really make the problem less likely, they can suffer stem rot up until the plant has around 8 sets of true leafs.
Perhaps as they were in soil, you never watered them quite as much or the soil pulled some of the moisture out of the root riot.

Anyhoo

Thaks mate.. I have 12 poper nice seeds comin from DP tomorrow so dont want to cock it up.. My first plants were from clones and although they are doing great.. I didnt start them myself..

Any tips to get that 95% sucessful they claim up to 100%.. Cheers mate..

[Floyd]

I would highly recommend using your root riots for your seeds, I have used a few different ways over the years and starting them in root riots causes the least stress to the seedling and is the most sterile. You can see my seedlings in my diary, they were started in root riots.
100% rate is the usual case if the seeds are high quality and fresh from a good vendor. Just don't drown them

My advice would be get rid of the heat mat

The light above a prop should give them all the heat they need unless only using tiny cfl's

I bet thats where your problem is

Looks like I got something right for once.

[MrSparkles]

Yea that heat mat was design for a snake tank so that was probaly way to hot.. high 20's

plus i did give them way to much water in retrospect as the first time I just left them for over a week instead of chcking them everyday..

Wanting to care to much killed them

THanks for all your help guys

Just so you know, this had nothing to do with them being in flower. Don't associate any of the problems with that.

I agree with owd and pots that your mat could be an issue, but I think this is another possible root (sorry) of your problem. Be careful when scraping your clones to expose the cambium because that, depending on how thick the clone is, can massively increase the chances of stem rot.
