I think environment is a main component when cloning = warmth and moisture , this is weird because I just finished up with a experiment on cloning today, what happed is I am moving over to organics from bottle nutrients. in my organic search I read a few times that Aloe makes for a very good cloning gel.
I do not think that the medium is to crucial as long as it is not to hot and the PH is sufficient ,
So I took 2 9 week old mothers same strain but different phenol type cut 4 clones from each mother
I always use FF happy frog as my clone and seedling medium, because my organic soil is to hot ,but I was out of happy frog and the nursery I get it from was closed, so I bought a cheep bag of Jobes organic potting soil.
I took 4 cutting 2 from each mother and used my usual method using clonex for the rooting gel , the other 4 cutting I took I used a Aloe plant I bought that same day the K-mart where I got the $6 jobes potting soil from
I slit open one of the Aloe plant leafs and stuck my cuttings in to be used as a cloning gel.
my normal time for a clone to take root is about 7 or 8 days ,but I leave them in my cloner set up for at least 10 - 14 days to give them a good hardy start , and it took 7 day before the 4 with clonex to take root as normal . But my surprise was the 4 cuttings that I used the Aloe plant had rooted in 4 day and very good rooting occurred.
These clones are 11 days old , I mostly can get almost 3 week before I have to transplant ,but the Aloe clones will have to be transplanted today.because of good fast rooting and the cheep potting soil I see is only good for about 2 weeks as they are showing they need some better soil.
