Power Plant Seedlings -- 6/10 Seedlings Lost on Days 4-5

Power Plant, non-feminized (from dutch passion), germinated IN rockwool, only very light initial nute. In light tight chest, 18/6 cycle with proper T5 bulb about 10-12" above plants.

Temp: ~21celcius
Humidity: ~80%


I did not pre-prepare the rockwool (D'OH), but kept it moist. The seeds germinated quickly , except one slower one, and I had 10/10 seedlings growing nicely between 1 - 1.5" high.


On day four, checked them in the morning, everything was looking great, with all 10 plants doing nicely.


I came home and two plants had tilted over/broke, and one had brown water collected on its leaves. Since water was beading on the leaves, I thought "too much humidity", took the dome off, and 2 hours later some more plants had wilted.

Put the dome back on, and now I only have 4 seedlings left. I kept them on 24 hour light from Day 4 evening to give them all the juice they could get.

One of those just lost its cotyledons (sp), and now I'm worried of losing these last few.

It was going so well.


Here are the pics below:

Now some have very dark cotyledon's...

I'm not very good with seedlings.. Just wanted to say the little ones being held up by the toothpick looking things is kinda cute,

Looks like your handling them to much. Put the humidity dome on and leave them alone. If your touching them to much in the seedling stage you will get germs on them and they will die.

id move that light a little closer, they look like they are stretching slightly which would make them weak

Too much water in the rockwool can kill them as well, they need water but they also need to breathe so be careful with that, keep it moist but not dump ;)
 
light def to far, there trying to get more light try keepin it around 4 to 6in
put your hand between the light and the plant if it feels to warm move it up little move to avoid burning hope this helps
