The smallest ones are usually like 40 sites or something.
For that few clones, I'd personally just use Rapid Rooters, or Root Riots.
They're really easy, and near impossible to mess up, given you have the proper conditions.
And I've used
Dip 'N Grow for all my cloning. It's WAY cheaper than all those cannabis specific cloning stuff, and I've never seen a difference.
I can tesify as well to the success of the cheap easy way...
my first cloning attempt was only 2 months ago and I got about an 85% rooting rate.
I use Rockwool cuts to root and
Clonex gel. Thats it. that simple.
First I soak my rockwool cubes in 5.5 ph water
then I use my plant trimmers to cut off a LENGTHY clone, making sure that I take the First cut SEVERAL INCHES under neath a node.
After I take the first "ROUGH" cut, I then take out my medical grade scalpel, and I submerge the cut in Water. once the Cut's bottom is FULLY SUBMERGED in the h2o I use the scalpel and make a diagonal cut.
Then I dip the clones bottom which i just cut directly in the
Clonex rooting gel. [ literally only a DIP in the gel then straight into the Rockwool cubes.
Then I place the clones in my clone tray and place the dome cover on. I usually mist spray a bit of water in the domes top before hand which increases the humidity.
Within a few days you should see roots. Once roots appear I slowly start taking the dome off - or open the dome ventilation slots if you have the one I have.
A couple days of slowly increasing the oxygen will allow the plants to final live on their own without the added humidity. Once the plants no longer need the dome they are ready to be transplanted and be grown out
You can tell when your clones are ready to have the dome off completely when they reach for the light and stand upward without ever wilting.
As long as roots appear, you are on the right track.
When you open the dome and then the plant goes from upright and reaching towards the light to wilted and droopy then you know your plant needs to keep the dome on and prop slightly MISTED for a few more days.
IMO the large cloner machines are for people who take ALOT of cuts frequently.. if your like myself, just a interested beginner who has a few strains at a time with a pretty low clone need.. then you can basically just cut clones when needed.
Hope that helped. Any questions ask.
