Correct. In 5 gallon buckets, a probe probably just barely reaches the water table, if at all. I'd drill a few holes so I could probe different areas by the side... I'd personally drill holes in at least the bottom third of the bucket, if not all over. Right now he needs to keep the top soil moist too though because he doesn't have a root system to reach the lower water in the soil... worry about the wet dry cycle when they're drinking better. Strong possibility the soil was too hot as well. I cook my soil for at least a month in the sun when I add organic amendments like that. If they weren't vigorous to begin with, they maybe couldn't handle it. Hopefully those will pull through, fingers crossed.This may help you with watering since you already have a moisture meter.

The other day I had an idea and after testing, it works great. To know if you need to water, get yourself a soil meter. Poke or drill 4 holes in your pot 1/4 way up from the bottom spaced around the pot. Insert the meter probe into the hole and test for moisture. If its dry, then water SLOWLY...www.thcfarmer.com
Often growers use domes over clones to help with humidity.
Rockwool was dry like I said earlier. That kinda limp stems is from lack of water. It woulda been fine if you had just watered it.Ok well I pulled the front one that at this point was a stick with everything hanging lifeless…… the rock wool was dry as I peeled it apart…. The soil was moist (not dry not wet)… the plant appeared dead… the “roots” looked the same as when I transplanted it 4 days ago.. about a 1/4 protruding… I am completely dumbfounded, I didn’t even bother replanting it in a solo cup
Stop severely underwatering them, and they'll start surviving. You need to saturate the entire media each watering letting it dry out between waterings. Check the weight of the pot to determine when it's actually dry. Way more accurate than that moisture meter you're using. Also, clones with little to no root systems need very little light 100-150 ppfd at first to grow roots properly. As the plant grows you can increase this as long as she's healthy. If not lower it back down.Rock wool didn’t play well with the soil? I’m pretty sure I’ve used clones in rock wool and soil before without this headache. The last run was in jiffy cubes. Before that there was about a 5 year gap where I wasn’t able to grow so it’s hard to remember what I was doing before. But…. It’s a fucking weed… I cannot for the life of me understand how I managed to kill 3 so far…
Moist upper soil and the perched water table are two different things. Here is a definition I copy pasted cause I'm wake and baking and can't use my brain currently lol.How would the moisture meter be reading moisture if it’s not reaching the water table? Wouldn’t it read dry if it wasn’t reaching? The probes are half way down into the soil, just below where the roots SHOULD be. Maybe I’m not watering thoroughly enough… but I’ve never had this problem, granted I only have maybe 6 runs under the belt. The meter says there’s water so I’m afraid of watering too often and drowning the baby roots. Also the water I’m using is just filtered water from the fridge, I let it sit for a day minimum to reach room temp (70ish). I guess it’s a compounding effect of a few things being off.. thank you all for the pointers, I will certainly take them into account in the future
consider next go-a-round _ try this week 1 -3 just use water and a good root stimulator ( here is growth cycle) --I’m having trouble with these clones I picked up, they looked really happy at first and went downhill each day.
They were rooted in rock wool (small roots about 1/4 inch protruding from bottom at transplant).
Soil is fox farm ocean Forest with some amendments I added Neem meal, Kelp meal, Alfalfa meal, charcoal and lava rock.
Light is 300 watt LED 24” at half power 18/6.
Temp is stable around 72, humidity was low at first around 30 but I added a humidifier now it’s around 50.
At first I thought I was over watering and I made some adjustments there.
The plants on the left are about a week and a half in the soil and are just barely alive…I lost two others already.. they looked super healthy when I first got them.
The plants on the right were transplanted 2 days ago and are starting to droop and act like the other ones did.. I’m at a loss trying to understand what I’m doing wrong. Never lost rooted clones like this…
I pulled two plants 2 days ago that I figured weren’t going to make it.. the roots hadn’t grown into the soil it seems… it’s like they just don’t want to grow in my soil mix…
I use rockwool exusively and while I'm not a pro, I have to wonder if your soil was actually wicking away all the water from the cube? I've found at least with rockwool to rockwool transplants, the bigger cube has a habit of drying out the cube on top/in the hole. I'll give the big block a good soaking prior to transplant then after that keep watering the little cube to keep it from drying out for the first few days.Rock wool didn’t play well with the soil?
