I've seen plenty of people grow amazing plants with rockwool in DWC systems so that's not a problem. Here's one: https://growdiaries.com/diaries/105420-grow-journal-by-hoodoo/week/541574

"Rockwool harnesses the power of natural stone to produce a fluffy and aerated growing medium ideal for cannabis growing. This material drains well, supports root development, and arrives in a cuboid shape that is easy to transplant into hydroponic or soil-based systems."

Guys help me out. I have tried shifting from soil to DWC, it's been nearly 2 months and I still haven't been successful. Temp, humidity (in the pics it's low right now on purpose), ppm and ph are correct. The nutes are correct. GH flora series line. The first seedling got root rot. Now I put...

Seed, DWC

So no nutes until the grodan is in the bucket net? At which point do I first introduce nutes?

It's my first time using rockwool, I got grodan 1 inch cubes. I know I have to soak for 24 hours and stabilize it at 5.5ph. I use GH nutes, my question is how much should I add per gallon for the initial soak?

They are white and no slime left. I wonder if the cause might the the lower water res though. Could it be that it can't get enough water with just the tip of the main root submerged in water? It's so small, seems unlikely

I didn't, was very careful with the dose

GH nutes but a lot of different products. Did a quick res change right now with just the flora trio and cal/mag with is the base line. I wonder if it will show in the next few hours if there is a change.

Or maybe too much nutes? I raised it for this new res. Should I fill the res again with less nutes?

Yes, I cleaned them up no slime anywhere anymore. Immediately after I did that the plant was droopy. Today the plant is dry and crispy. It's over, I'm sad. The pH and temps are right. 2 culprits, humidity was way too high for a bit, I fixed it to no avail. I also lowered the res water level...

Anyone knows what these marks mean? I read a couple of different things

The plant has continued growing but now I'm seeing symptoms of something being off

It's tap water

Then I got my answer, I hope they survive a few days if the store is closed tomorrow

All GH nutes besides the microbes. It got like this very very fast, first few days and the color is from the nutes. Not sure if it's really slime but I'm scared that if I wait for symptoms it may already be late.

I'll get this tomorrow https://www.canadiantire.ca/en/pdp/hth-sock-it-454g-0813704p.html#srp

I'll buy some, which one do you use? I see 6 different ones in my local store

So it it slime? What have I done wrong to get slime so early almost immediately after starting? Those few extra degrees of res temp? It's still a seed and 11 days of my time, so I would like to try to make it work.

That doesn't help me but thanks.
