Poor seedlings

Alright so from what I've gathered, you have a room with a veg and seedling area; within that room, is a tent with plants flowering. Your "room" RH is 18%, and your "tent" RH is 50%.

In my general experience you would be need an industrial sized humidifier to change your tent RH drastically, so I wouldn't worry about that at all.

Here are some issues associated with low humidity:

  • Wilting
  • Dry leaves
  • Decreased growth rate
  • Curling of the leaf tips
  • Tip decay
I believe these issues correlate to your pictures, although that doesn't mean causation.


So yeah, you'll need a desktop humidifier. They're small and discrete. I would look on amazon, or the big department stores.

Some basic brands are: vicks vapour rub, pure guardian, and a host of others that sell them for kids rooms.


You're not looking to change the humidity of the entire room, just around your seedings. What I do is set up the humidifier close to the plants and use a small computer fan to blow humid air directly on to the young plants.

Hope this helped

Just weird that i have never had this issue with humidity like that. Must be the strain. I cant get a humidifier for a few days cuz im too busy so i just made a ghetto humidity dome for em.

Yea i knew it was low just didnt think it would really be that big of a deal. Problem with humidifying is those seedlings arent all i have going. I have 3 flowering in a tent in the same room. And the rh in that tent is like 30% higher from all the vegetation. So 50% rh for the seedlings turns into 80% in the flower tent.
EDIT:
So its not actually 30% higher. Right now its 18% higher

It's not. It can be but I run low humidity.

I think you got it. Raise the light and transplant should help.

In my experience seedlings respond well to higher humidity, so again I wouldn't count it out as an issue. Let me know if you see any visible improvements with the dome.

Doesn't really look like light burn to me, but you could be right.

Yeah, that is pretty odd. What strain are you growing out?

I'm with Mr white on this one man.
You've already transplanted. Just raise the light a little.
As long as the air isnt really warm, low humidity shouldn't be a major concern.

It wouldn't surprise me still, if its your mix.

What's different about this grow? (Lights, mediums, fertilizer etc)

I grow in low rh all the time. I prefer low humidity.

Not so much light burn as light stress.

It may be the mix but mg seed starter isn't really hot.

Its sensi skunk by sensi seeds.
I transplanted, moved the lights up and got em in domes.

From what I can see, you're having two issues. Over watering, and low humidity.

For humidity, refer to my precious post.

For watering, keep the soil uniformly moist, not water logged(yours looks waterlogged so use that as a reference now) . Let the surface dry about 1/4 of and inch(about half your thumb nail) before watering agin. Discipline is the key.

Good luck.

Sorry, my mistake too. I meant to say "as long as the air ISN'T really warm, low humidity shouldn't be a problem".


It just seems like the mix, to me. When I've had seedlings look the same as those, it was always my mix.

So i just flushed em really hard. The only thing it can be is the mix. I domed em, raised the light, lowered temps even, and they're worse. Lets hope the flush helped.

yo grumble, check out rapid rooter plugs by GH, use those and a 10$ germination mat from amazon with your veg box, or use a big tupperware box (or a jiffy plug box from walmart) with a lil bit of water. you will have a 95% success rate my friend

It looks to me as if you have something called "damping off" which is when a fungus disease attacks the roots and base of seedlings and clones. The number one cause of damping off is over watering.

The original overwatering is probably your culprit.

The key to a healthy harvest is a healthy seedlings. Not to say those will never bounce back, but it will never be optimal.

If you can afford it, I would germinate new seeds; and then reassess your watering.

For seedings id let them dry a 1/4 inch before further watering. Don't reuse the soil in your cups though, it may be infected with fungus.

Do you have any other plants in the same soil mix? If so, how are those doing?

Must be some sort of contamination, you never really know what's going on below the soil, although contaminated soil is usually more catastrophic, with little or no growth.

Here's what your problem isn't:

  • Humidity
  • Damping off ( above ground)
  • Light and temperature issues
  • Over-watering

Possible Causality:

  • Ph, and ECE issues
  • Nutrient deficiencies/ over fertilization
  • Soil contamination(fungus)
  • Water contamination.

Hopefully the flush helps

Something just came to my attention.

Are you re-using old pots? If you are, and you didn't give them a good clean, this could be the source of contamination.

It could be something as small as salt build up on the container impacting the soil quality,
