They are kept moist and have been from the start, they have little air as they are in a heated propagator with the top just cracked open slightly to keep it nice and humid.

Yes I am using clonex gel

Some more info perhaps I should have given is:-

They are in rockwool cube that have been soaked and shook out some, I cut them on a 45 angle with a blade cleaned in surgical spirits I split the bottom of the stem and scraped around the outside of the bottom stem, dipped in some fresh clonex gel and poped them into the cubes, I then misted the top.

The only thing I did this time that didn't seem quite right to me but I followed the advice in the Jorge Cervantis book was to pour some 5.6ph water into the bottom of the tray with the rockwool cube in, from what I can see this wicked straight up into the rockwool and possibly these are now too wet.

I am visiting the propagator twice a day and misting inside the lid.

Can anybody advise where I am going wrong please also are they screwed now they have flopped or might they be ok?

Thanks all
