ANyone I'm fucking sick of this cutting shit..
- I cut at a 45 degree angle
- use rooting hormones
-18/6 light schedule with a 40 watt bulb 4 feet away not shinning directly on it.
- ppm of about 300 ( tap water is 175), when I was using straight tap water roots were not as thick.
Stop messing around and get an aero-cloner. Clone king or a DIY aeroponic style cloners work great; 99% success rate and zero root hormone is needed. They really are worth trying an investment; you can sell/trade the extras. I have tried to root cuttings every way possible and can tell you they usually tend to look kinda sad before they propagate & begin to recover. Sure you can root cuttings in rockwool or even a cup of water but it takes longer w/lower success rate.
Some other tips for rooting cuttings include running 6500k fluorescent light (aka daylight full spectrum) 24 hrs a day. Cfls or long bar style fluorescents usually work well; keep them 12-18” away from canopy. 4ft seems way too far to me. No dark period is needed until they root. Without roots nothing can be absorbed by the plant so adding 300ppm of whatever does not really help even if you think it does. Ph adjusting the water is same kinda thing; don’t even bother. Doesn’t even matter how you cut as long as the cuts are sharp; use a razor.
Pro tip: use a recycle timer set to 1 min on 1 min off so the water and pump stays cool. Makes for faster rooting; should be getting roots in a week or so. Much longer than that usually means stems are rotting. Clones are only as healthy as the mother plant. A healthy lush green mama gives the clones enough N to get them through rooting.
