Seedlings won't grow

Seedling in my aerogarden, 2 reputable auto seeds are having troubles getting past baby sproutlings.

Their in rockwool and have been at the same size since the first day they sprouted.

The reason i'm concerned is that autoflower seeds only have a set ammount of life in then, so if it takes 2 weeks to pass through this seedling stunt then I will barely get a yield.

They have been the same size for 3 days, they also got to that size over 1 night.....

What could I possibly have done wrong?? The temperature in the room is 25 celcius 21 low 27 high. Humidity is 40%-50%. I have an external air pump connected to an airstone within the aerogarden

Are u using any nutes? How does that machine water? Is it always watering the plant?
RH could be a lil higher might help.

Obviously won't be using nutrients untill it has a few set's of true leaves.

I've done months of research before planting, I don't understand what the problem could be!!!

Not using the built in aerogarden drip system, just the external pump with airstone, also have put few drops of water on rockwool evey now and then to keep moist

Ran into a similar problem with rockwool. I'm thinking because there are no nutrients in rockwool (as compared to all the goodies in soil), there is nothing for the seedling to use to grow - beyond what was stored within the seed. I took mine out of the rockwool and put in soil, now they have taken off growing again. I believe the solution is there somewhere... Good luck

Thanks for the input lebowski-
Might just have to transplant them into soil untill they have some roots

Edit: wow okay, so it turns out night after I spray my grow area to raise humidity from 40-55% humidity, I realize there's this gross mildew over the mylar that had some mist on it.

So now I go to taste what is in the bottle, hmm- some sort of cleaning product diluted with water???!?!
Refilled it with WATER and sprayed the area and my 1 still live sproutling to get humidity from 45%-60% I've seen sproutlings like humid area's, non cleaning product enviroments too, so wish me luck in the next few days

REGARDLESS- It is an afghan kush ryder, autoflowering, meaning I've already wasted 'bout 5/65 livable days

New: It seems that it has grown a 3rd set of leaves at less than an inch height, it's first set of spiked leaves are falling downward and yellow at tips, and the first 2 sprout leaves are drooping downward aswell
This is a very sad thing, my easy rider is already dead and my afghan kush ryder is having a really hard time progressing, also just dropped 2 drops of lemon juice in the res to hope to bring the pH down just a few .0's
Also syphoned out some water, water in the res is about half inch under the bottom of rockwool.
Should I pull my net out and see if the rockwool is too compact?

Please help, this is sad and pathetic, I wasted money and time on these seeds for nothing!

Go soil dude its a lot easier I am doing a hydroponics nut idk what all these types are I've done so much research the best way IMO is whatni did for cheap....got a 45 gal bin from wmart 19$
Got five 6" net pots and cut holes in the wmart bin to slide em in
Put water level 1" BELOW bottom of where the pot hangs....not 1" from the lid.....
Put 4 big ass air stones in there.....2$
Put a 1,000 gph submersible pump from petco....50$ ( just put the pump in to circulate water better nothing special leave on all day with the air stones
Leave my plants in rapid rooter trays with a cfl light until they get a few inches or root bound and then I just put the whole rapid rooter with the plant into the pot with clay pellets to secure it....

FYI rock wool is annoying I hear never used but ph fluctuates real bad when it dries out so it's more for advanced users or people that like messing with ph and that stuff all day.....and oh ya I will b using tap until I get an ro unit and just add some 3$ dechlorinator and ph down/up depending on what it needs....I am keeping it in my closet and my house stays around 67 so my res should stay cool. Maybe that's ur problem since I've been reading about hydro one of the most important things is the res temp 25 cel is like hmmm it's 9/5 plus 32 so if your at 77 degrees farenheight with the light and everything I'm sure your res is well over 80degrees F= not good fr your weed u want it around like 67-75 for the water maybe get a chiller kinda costly but worthy in the long run

I've aslo never grown hydro so I wouldn't be the one to ask I just am an addict of reading on different ways to grow so it's just my outside perspective and it's probably not the best...but for sure on the res temp if it's really 77 and you have a light what kind of light? If your kickin out a 600 w Mh that res could be 90!

it's like 108 watt cfl in the aerogarden hood, the res temp is lukewarm-warm

Dude pics would help tons. I am thinking that you are trying too hard most likely. Sounds to me like the RH is a little to low for the early stages of growth. I would start off at 60-70% RH. The other thing I imagine is happening is you are keeping the rockwool too wet. Let it dry out before watering again. As a final suggestion I would get away from rockwool anyways and go with some thing like rapid rooters.

I have cloned many plants in a simple cloner machine running one 360 ez cloner sprayer with straight tap water and no medium. The trick to getting them to root in any hydro machine is not over watering them. I figured it out by accident really. One day I unplugged the cloner and forgot about it. None of the clones had rooted yet but when i came back more than half had sprouted roots looking for water.

Keeping the stems too wet results in one of two things;
1. Plant gets stem rot
2. Plant lives without roots.

The real key is to stress it just enough to encourage it to try and find water on its own. This is obv a fine line since if you dont water them for too long they will die unless they reach the water on their own. Recently I started using rapid rooters and some cloning gel. They seemed to work great. I just soaked the rapid rooters with R/o water and waited till they dried out and repeated approx every day or every other day.

If you plan to grow in hrdro dont start your plant in dirt since the process of changing it over will only stress your plant. I have faith that you can get them popping roots in hydro.

PS- buy a new spray bottle since chemicals don't always wash out well and you do not want any trace chemicals on your plants. If it was mildew and not chemical residue i would wipe it with a very mild bleach solution.

Hope this helps you out some

Edit: Seeing as she has been alive for a week or so, growth or no growth above ground, would it be an alright idea to put some aerogarden tab liquid into the rockwool to enrich the taproot with some sort of accelerant?

I added a fan for air circulation, squeezed residual moisture out of the rockwool, pulled her up a tad bit, I may have planted her abit deep, I also am having foggy memories of the taproot being in a slight spindle... But before I pulled her up slightly I was noticing her taproot poking out of the medium, hoping it will poke through again and make it to the water before dying.

Oh yeah, and 1 of the 2 was dead quite some time ago.

I put half my aero nutrient tabs in the freezer, and using them (IN THE PACKAGE) in my resevoir as a chiller for the water so it doesn't get hotter than the outside temp which seems to be staying around 26c
If this doesn't succeed I'll need to get some trusty aerogarden peat medium and new seeds, bringing my total investment way up...

Her 2 first leaves are already yellow (wth,) she doesn't have 1 node yet, just 6 baby leaves. Maybe fem's and auto's and rockwool arn't meant for beginners, let's try again
