Gerninated seed stalks are failing me. Tell me why please

**ShibaSpeak** · 08-09-11, 07:40 PM

Last batch of seeds I had I put half straight in soil and germinated the other half. I got about the same success rate from both but the germinated plants are coming up with super weak stalks that are breaking even though I I followed the guide on here to a T.

During sprout I have them under a fluorescent about 5 inches away and a 450 watt MH bulb I was going to move them under after about a week. I have a T5 on the way as well.

Should I
A) Put my germinated seeds further down in the soil
B) Move the fluorescent light closer
C) Put them straight under the T5 light
D) Something completely different or a combination of things listed above

or E,
check humidity.
too high a humidity causes a week stem on seedlings

are they in a propagator?

D would be E but thanks :P

I live in a low humidity environment and havent added an extra besides foiliar spraying on my larger plants so I dont think that would be it.

are the stems soft or hard?

No propagator, humidity is low, temps is high 70s/low 80s (I know I need a thermometer but the rooms currently a build in progress)

what are these temps in celcius?
i dont use farenhieght sorry.
i also use coco 100%.

ive had the soft stems that makes the seedling fall over and its mostly been down to high temp + humidity
or 2 much light forcing growth that the root system cant yet support.

A propagator would help, even cling film over some kind of dish, but I think you are frying them with the soil

What soil are you using?, you should be using seed and cutting compost with about 20% perlite.

not a fail, a lesson !

Wouldnt a propagator raise the humidity which would be bad? I also have a 72 site one with heat mat on the way.
