Overwatered in DWC rock wool? Safe repot ideas?
EvilGrowerstarted grow question 5y ago
Is this seedling overwatered? Growing in DWC hydroponics. It's been wilted the past 2 days.
Any ideas how to safely adjust the setup so it will be less wet? I'm scared to repot because I may damage the root.

ok, that's good, but yes, if there's a lot of water splashing onto it, then it won't have a lot of time to dry up..
take the net-cup out and see how high the splashing can go.. then hold your hand there and see how wet you get.. then imagine the rockwool being a sponge to absorb it all..
i was quite surprised with my first DWC grow about that as well, so since then i put it, so only the highest splashes reach it..
in the first days I was worried that I actually had to monitor that the rockwool wouldn't dry up completely, but that never happened so far..

.. and yes, try to get your humidity much higher up as well. around 70% would be great during this stage. veg-state as well.. during bloom it should be down to 50 if possible..

The rock wool is above the water level and only is watered from the water splashing. Could it be too wet from that? The RH is around 40% if that could be why the leaves are drooping.

I hope the rockwool or the clay aren't submerged in the water, are they?
Rockwool can store quite a lot of water (especially for seedlings), so it shouldn't be necessary to wet it for another few days.
What i do with my DWC is i hang the bottom of the net cup just above the water-level, so that the bubbles from the airstone lightly splash on it from below.. that's it.

Just started week 8 and buds are growing day by day but I have really low expectations in terms of quantity.
As you can see I failed applying LST + some yellow leaves, gave them chelated iron .
Please share your thoughts and tell me how long I must wait for the harvest.

Flushing with RO Water (EC 0,0) or tap water (EC 0,8)?Hi.
I think, it's 1,5-2 weeks before they are ready to harvest.
Tell me, if you see something else in the pics. :)
I want to flush them now every 2 days with only water.
I have the opportunity of RO Water (EC 0,0).
Should i use the RO water or normal tap water (EC 0,8)?
