Ok now we’re getting to some possible causes. Cheap fish tank heater, decided go back to read reviews, its off by up to 5 degrees or more.
Put a turkey probe in the neoprene to sit like it would a cutting and its not bad but is 68-69F with heater set to 71F.
Clone king manual swears fixing temps solves the issue. These cuttings look ultra weird, cannot tell if rotting or rooting. The kln may up my odds.
They do say start with nothing and add as you go a long I never knew rooting hormone was a true product worth using. I think its rooting from the sides more vs only from the cut sight last time.
Optimistic for next run, I had brag-able results last time. Squid roots. 1 month later ready to flip.
I had it set to 68F for most the 19 days so it would of been too cold to see last times results again.
I would suggest get rid of the humidity dome on an aero cloner or bubble cloner (only use a dome for every other method of cloning)
The humidity dome will encourage bacterial growth. On an aero or bubble setup the water from the reservoir should be enough where you do not need the foliage to be inside a dome. In fact it can perform worse
The light source if too bright will delay cloning. This is very important
Using a fresh razor, clean the oil off with some alcohol and wipe dry. Use a site that hopefully has 2 nodes staggered closely above your 45 degree cut so you get 3 root locations. Sterilize the razor with a liter each cut.
Put them in the cloner being careful not to let any cut vegetation fall in. I like to change the water after one day. If using town water there is typically chloramine in it which will keep it sterile. If using well water I'd add clorox bleach to sterilize the res. I change the water every 3-4 days after the first change which is purely to get rid of contaminants.
Moving forward any wilted clones need to be removed so they don't funk the res up. Focusing on sharp cuts and clean water was a big game changer for me, ditching all additives because the real goal is to get them to suck up water from the cuts in the res, not make them grow
Temp is important and some plants just are hard to clone also. It can help to try different age clones some like to root when they are Woodier and some more fleshy, and some in between. Seeing what works well for your specific strain helps but sometimes certain ones just suck to clone.
