How are you folks keeping the roots in the cup? I can’t.

There’s no holes in the bottom of my cup, so the roots haven’t tried growing out of them yet. Note, there is a hole in the side of my cups, hempy bucket style.

I let them dry out in between waterings. at 24/0 with the temps being 25c on average that only takes a few hours so it’s AM and PM waterings for me

I’m still watering once per day, but expect to need to up it to twice per day soon. I made the “resivoir” a bit deeper and added more vermiculite than I normally would.

When they start poking out the bottom, I snip them off with my thumbnail.
I am top and bottom watering, twice a day right now. Morning each cup gets 90ml of feed, just enough to start runoff, and 120ml in the saucer. Repeat at night.

by chance did you do the three point calibration before you used it? even the good ones require calibration. they usually include the three references as little packets of powder that you mix with ro water.

I use a small soldering iron so I can hear them scream, one by one. Once I’m halfway through the other roots have retracted spontaneously. I’m Severely disappointed they don’t have leather covered solo cups, like those dice cup things.

My current personal favourite meter and I’m using my second in 4 years. I murdered the 1st one from use and follow these rules:
- Calibrate to 7.0 at minimum 1x a month.
- Before calibration clean with designated toothbrush in distilled water.
- 1x a month squeeze out fluid in sensor sponge and add a few drops of fresh storage solution.
If anyone thinks this is OCD a growmie that know from a shop has 3x meter’s on him in his kit anytime he goes to do a house-call.

Just got our new Blue Labs meter… got it from them because we had truncheons from them that lasted many many years-- the ppm/TDK truncheon still works- and we bought that in 2009!
Sorry, but the cheap, yellow ones from Vivosun are crap–one only worked for about 2 months then wouldn’t recalibrate- the 2nd one I bought never worked at all… again, you get what you pay for…but really expected more than total silence from Vivosun when I contacted them
about it…

Here is my weirdo skunk and one of the Lennon/Skywalker Ghost Triangle Kush flipped yesterday. Now that I suspect the weirdo might be a male I might grab one more of the other entries and toss into flower as well. The rest I decided to grow out rather than enter against these monsters you people have going.
