Cloning in water - a P.S.A. about pennysmart cups

Old habits die hard. Early on, I just couldn't get regular cloning to work, but I found water culture worked, although slower than some growers reported for using media. So I kept using it. Very space efficient also, i can wedge over thirty cuts in a single cup.

Nothing special to the procedure. Find 6" of healthy growth, strip the bottom 4", cut it off the mother, and place it in water immediately in a new disposable cup, and label the cup. Depending on strain, I got 100% by a week, or 50% in two months.

My track record fell apart about a year ago though. Batch after batch turned slimy or mushy within two weeks. I think in the past year I've only gotten four cuts to root.

Two weeks ago, I ran out of cups. Finished up the last sleeve of these. I think I had bought four sleeves of these ♻️ 6 polypropylene cups.

In a pinch, I grabbed a random clear disposable PLA cup the missus uses for smoothies. Nine days ago, I prepared twelve cuts for water culture. Today I have white bumps ready to throw roots on eleven of twelve. This mother has failed on three rounds of cuts at twelve to twenty cuts per try.

Nothing else has changed, aside from the cups.

In the past year, I've blamed my water, and bought water.
I've blamed machining oil or the metallurgy of my blades, and gone as far as buying a ceramic razor, like the knives they use to keep salad from browning.
Grasping at straws, I'd replaced my bulb, thinking it's degrading had it making some evil rays, and even switched to LEDs.
I tried super sanitation with hypochlorous acid, gloves, and a janky glove box.
I faced north, during a full moon, in a ring of dogwood ash and raven feathers, while holding rose quartz.

And nothing changed.

Until I tried a new cup. Same tap water that's failed too many times. Same mother that's failed to give me a cut in three tries. Same environment. Same light.

Reminds me of the toxic tent syndrome, and the hydroponic hoses before that, and junk nursery pots prior, that gave off phytotoxic chemicals.

You can do as you like with this tale, but for myself I see a year worth of depression, frustration, self doubt, and zero progress, available at a Meijer near you for only $6.

Thoughts? Web searching really didn't pinpoint anything specific to polypropylene so I'm leaning toward an additive like plasticizers, which have been in the spotlight for being toxic and/or hormone disruptors.
 
Ive been cloning since 2008. I've tried it all, RW cubes, coco pucks, root riot plugs, aero cloner, cutting in direct soil, and in cups of water. Still going strong with an aero cloner. I was running up to 12x 25 site aero cloners at the same time. I use tap water, ph to 6.0. Been using tap after a few tried and failed attempts with bubbled water. Tap is the best (imo). Some people add pool shock (aka chlorine) to their distilled aero cloner water. Ummmm, tap water already has chlorine in it, so your wasting $ on pool shock vs tap h20.

Cleaning the aero cloner is KEY to success. 24hr run with bleach (1 cap) and tap water, rinse. 24hr run with 1 bottle 3% h202 and tap water, rinse. 24hr run time with just tap water. Drain and let dry.

Im using the same pucks and collars for 5+yrs.
 
Southeast Michigan, and we have great tap water. It's never given me issues, and the city reports we use chlorine instead of chloramine.

I was close to building a bubble bucket, but really don't have the floor space. Coming from bigger things in my bachelor days, I'm embracing the challenge to make the things I want to happen, happen, with a reduced floor plan, and a wife that understandably doesn't want to live in a greenhouse.

Im just beyond ecstatic that I have white bumps again. I was living vicariously through the Internet and photos, lol.

I've cloned in old stubby bottles in summer outdoors in plain tap water. Some cuts clone easier, faster. Like demon says I've got an aero closer which makes it easier. But I tell you I might just try a comparison for arguments sake. Brown stubby bottle, willow water v aeroplanes and compare the pair.
 
It's definitely the cups. The day before I posted this, I let my neighbor in on that, and he finally found success. I got roots on all twelve and let the fittest six move forward.

i have always felt like I see a few weeks of chlorosis when I swap my mylar also. I wonder if there's something similar going on there. I'm starting to question anything everything plastic in my grow at this point.
