So bit of back story,
Lots of growns sucessful with dirt,perlite,drip,hempty and smaller DWC.
Last grow in 5gal DWC no issues at all.
Grow before in 3gal DWC space issue.



Just steeped up to 10gal since wanted to go big this time and im having a hard time even starting off.
Steeped up to 10watt 4 port air pump with 4X 60mm air stones.

Using 150mm netpot with 180mm rockwool cube compressed into it.
White bucket thats been wrapped in reflective tape,
5X Creecob.
5.7 PH
300ppm
12-14c res temps.

Tap root touches the bottom of the bucket, Thats the only thing thats grown in the last week.
Plant looks very over watered,

Had water level set to 50mm below net pot (2inch as per having read is best)
Day one checking on plant had gone from looking ideal to leavings facing downwards.
Did PH and ppm check and was good. Lid of bucket was dripping wet and rockwool soaked.
Added a breather hole, and same issue next day.
Dropped water level to 3/4 level, root growth really took off, But still droopy.
Waited 4 days and no improvement other then massive root growth.
Just did flush and been no nute uptake, Have lowered water level to 1/2 since rockwool was still dripping wet. Slightly squeezing it could easily fill a cup with water.

So the question is,
Am I right in thinking its the condensation causing the issue. Do I need to add a bigger breather hole its 100mm at the moment since I had a spare netpot that size. Or something else?

i never had an issue with condensation causing overwetting, i use rapid rooters though, not rockwool. If you are squeezing that much water outta the rockwool then that's your problem. Maybe with your setup the rockwool is wicking that condensation? Pics?

What do you mean by breather hole? Pics?

your medium is the problem. if i were you, i'd try to cut the plant out of the rockwool block very gently and buy yourself some hydroton. put the plant in the netpot and gently fill up around it wiht the hydroton.

I start seeds on aerocloner and xfer to netpots in hydroton. Avoids a starter medium.

I hate rockwool.

Droopy leaves are from low o2 which is from too much water in the cubes.
