Clones root fine but will not grow

Hi:
I have a friend who is trying to grow clones with no success.

She clipped clones; 3 tiers+; snip lowest leaves; cut stem on diag. just below clipped leaves; dip in Clonex® 48 hrs in distilled water.
Then she puts them in clear plastic cups; 50% perlite / 50% potting soil with no organics; again dipped in Clonex®.

Nutes:
General Hydroponics grow micro bloom - 1/4 tsp per gallon distilled water + 1 ml of Root Excelurator®.
Clones are under a cloning dome to keep humidity up; light is 2 4' flourescent 'daylight' tubes.
The dome walls are pretty much covered in dew, though they weren't as much when she started the clones.

The clones root just fine. They look real healthy after about 2 weeks.
We can see roots inside the edges of the cups.

She's done it with 12 clones so far.
They absolutely will not grow.

How can she make the clones grow?

How long has it been since she took the cuttings off the mother plant? When I take clones I will usually have roots within 10 days but as far as growth if u have them in solo cups I have noticed they take longer to get growing. So what I do now is put them in 1 gallon pots and watch them take off.

It's been a bit over 2 weeks.
She's tried putting them in 5 gallon pots once before and no cigar.
She can't make them grow.

If the clones are rooted then they are probably ready for a light feeding. How much light exactly are they under at this point? What medium are you transplanting into?

i have found that clones are slower to grow as well. you might try a light feeding like southerner suggests, for me the trick to get more rapid growth right away was light.

when my clones get done rooting, they get a step up in light. they root under generic 13 watt fluorescent daylight bulbs, then they get set under 110 watts of high output T5 lights in the 6400K spectrum.



not sure what it is about this light, but newly rooted clones love it. rooting clones and established plants don't seem to derive the same benefit.

You don't clearly state what happens to the clones other than 'they won't grow'. What exactly is happening... do they die?

Only thing I can think of (if they are in fact dying off), is cold temps. What are your temps in your clone area?

It's been over 2 weeks since the clones rooted? Is that right? A 5 gallon is very large for a newly rooted clone -- I think every1 would benefit from a picture because your description is rather vague.

Yes, just a bit over 2 weeks now.
Again, "The clones root just fine. They look real healthy after about 2 weeks."

I did forget to mention that they're in a tray sitting on a heating pad on low.
The temp inside the dome is warm.

They are not dying. They look great, just no new growth.
She dropped the light (again, 2 4' daylight florescent tubes) right on top of the dome.
Maybe that will help.

heating pads suck, once they root, they need fresh c02, get the dome off and get a fan blowing across them so they can respire and transpire. lose the distilled water too.

Have her place the cuts in solid color cup, not clear.

Once my have clones have roots they go into 1 gl coco pots and will just sit there while the roots go crazy, after 5-6 days I have to keep a close eye on my light height.

It's important to keep the roots dark.

The roots are in dirt now (50% perlite / 50% non-organic potting soil).
They'll be transplanted to 5 gallon pots; 1/3 perlite / 2/3 potting soil once they're growing.

She put the 2 flourescent tubes right over the dome and that definitely helped.
She can see minor growth now.

OK, She'll lose the dome and it's very well ventilated w/ 2 high power (tunnel??) fans.
Lose the heating pad too?
It's a bit chilly at night. That'd drastically change the temp of the dirt.

warm for rooting clones, but after they root, yea drop the pad, encouraging more 'bad' things to grow than good once u have ur roots.

Ur cloning is over, you want to veg now. So lose the cloning gear, the mat, the dome, the cups.... drop into a larger pot, have airflow but not enough its shoving the plant around, or it will be wind damaged. Is there a real light they will be going under?
