Thanks, I did exactly that 24 hours ago and they still look perfect. I am surprised. They don't look saggy, or shriveled, or anything, just normal. I lightly misted them a bit ago.
So you are saying you have the rockwool in a container partially submerged in water the whole time? I have read you do not want them to moist.
NO, NO, NOOOOOO Never leave rockwool in water. It won't be able to take up air and you'll rot your cuttings. In fact, if it is a flat plastic bottom, you need just a bit of perlite under the rockwool.
To quote from the 1989 (?), SSSC catalog "... On a flat plastic surface without perlite the blocks would suck themselves fixed as it were. The water/air ratio in the blocks would then be seriously out of balance, which would result in rotting at the base of the cuttings."
They also say that the cfl should be about 2' away from the cuttings.
My super duper cloning machine and mommy area is nothing more than a shop light suspended from a sawhorse with a timer. The 2 grow bulbs cost about as much as everything else together.
The 'cloning chambers' are clear plastic storage boxes (about the size of a shoebox), from the dollar store. I leave the lids on for perhaps 48 hours max, then just open to the air, no misting. Might lose 2 out of 50, usually less.
The trick is, good stems on the cuttings. Keep the mommy's on a low N diet for nice firm, strong growth. High phos is good.
Besides all the high tech stuff, I use:
Clonex rooting gel
Clonex rooting solution
3"x3"x2 1/2" (no hole) rockwool cubes, 4 cuttings/cube.
I've used the 1 1/2"x1 1/2" cubes and they work fine, it's just easier for me to handle the 3" cubes since I water by hand, dunking them in the rooting solution. Plus, I only need to water every second or third day with the larger cubes.
Hope this helps. If you have any ???, sing out.
