Seedlings

Okay so it's been 24hrs and they haven't moved or anything the rock wool this morning was getting a little dry so I watered it, but someone was telling me I might of been cooking them cause I had them roughly 19 inches for my 250w mh with a dome on it but they were showing progress in the dome so any suggestions are they fine and I'm just freaking out ?

Lol how old are they? If your seedlings are in right conditions they are developing a root system first then foliage.

Peace

There day 3 of being in rock wool here's a pic.

I didn't have a thermometer at first so when I got it they were like 90 in the dome so took of the dome put up some fans one blows on them but from a far and temp is now 76-80

Why are you worrying for? They have popped out and that is good, Patience is the key to success!

awwwwww they cute!

They look great…but a couple of things:

1) The light might be strong for seedlings that young. I keep mine under a 40W CFL desk lamp for the first week, just an inch or two away.

2) Personally, I don't think you should be top watering. Every time I've done that, I've invited damping off disease. I keep the cubes out of the molded plastic tray and when they feel light when I lift them, I bottom water by dipping the cube in a bowl of water so that it seeps halfway up the sides. Keep the tops dry.

3) Domes are for clones…from seed you keep the tray open.

Judge Mental is right -- they're growing roots, too, not just leaves, so you might not be aware of the growing that's going on inside the cube. Be patient!

Thanks I appreciate the feed back just my first grow

That's debatable. They don't call them germination domes for nothing. I've had good results with a dome and heatmat combo. If you don't use a dome you have to really stay on top of things b/c it doesn't take long for the small starter cube to dry out and if it does dry out you're screwed. The dome gives a stable humidity level. You just have to get the seedling out at the proper time to avoid the damping off. Even if you get damping off when you get the seedling out if goes away in short order.

Damping off goes away? Really? Every seedling I've ever had with damping off dies because of it. How do you preserve the seedling one damping off starts?

I thought damping off was the white fuzz that sometimes forms on the stem of germinating seedlings in a dome. That white fuzz goes away quickly once you get the seedling out of the dome.

I've never had damping off and I hope I never do. I am getting awesome results in my dome however.

for the one with the helmet, take some tweezers or needlenose pliers and gently pinch/crack the husk and remove it. if the membrane is still on the cotyledon's, wet your finger and thumb and gently rub it off. that will let that one get started. i'll be watching swish...

I've seen some guys talk about using a perilite covered base with rockwool cubes on top, in a dome...thoughts on that? I was curious how effective this would be for drying out and moisture levels; I thought it look legit and could help with both.
