I took some cuttings from a few plants and had them spend one night with 18/6 then the last 9 days with 24/0.

When the cuttings went in the new space they were quite wilted. Within 24hours of continuous light they were very erect. Also in the room are 3 potted clones that are now entering day 25/26 of veg since acquired. All plants show good signs of life having been under 24/0 for some 9 days.

Yesterday I thought I had achieved my week long propagation period of 24/0, so I added a timer inline with the light and commenced 18/6. One of the cubes has started to show numerous thick roots emerging from the cube. All the cuttings are showing good signs of health, but not all are showing their roots.

I've never delved into taking cuttings from my own mothers until now, so this is much to do with experimentation that perfection of current methods. I think 9 days is quite long for rooting time...

I will take some more cuttings once these ones are rooted and see if 48/0 then 18/6 give the cuttings such an abundance of energy that I can get my cuttings rooted in less that the present time its taking.
