Same here. Tiny seeds,which usually doesnt mean much, but only 2 sprouted. This was the arcata ghost.
That's how I do it as well. They have only been in soil for 24 hours, but after soaking...only 3 sank and 1 had a tap.
They probably will pop shortly. Personally i don't put much stock in the sinking floating thing.
Is that a coco perlite mix you have them seeds in?
Yes roughly 50-50 mix
Ive had that happen twice, once I was convinced it was due to too much mykos or perlite in homeade mix, I accidentally spilled the whole lil bag of mykos and put way more perlite in that I wanted into a tote of mix. I could wipe that white film gently off, and it would be there next day, but finally left and they grew out of it. Another time, I thought it had something to do with too much air flow at too low temp and too low humidity at that young age. Not happened since I got new mix. jme
I don't think anyone said the entire pack wasn't germinating.. Reading is fundamental..
What i had was not damping off some kind of fungus i guess. I here what your saying about daily irrigation in the coco with seedlings and may try it. I treat it like soil until i have a established root ball ( 2 weeks or better) trying to get the roots to stretch. I am not throwing over watering issue's at you butt are you saying you cant over water in coco?
Ive heard that you can over water an "underdeveloped" root system that cant handle multiple feeds per day. Thats why its important to water just once a day when watering seedlings. I did a test once (not in a solo cup) with a seedling and pure coco in a one gallon Radical bag once, I fed the seedling 6 times a day and it grew and did not die or show signs of overwatering. I think it was because of the radicle bags because they let so much air go into the media you use. So that "overwatering" myth in coco for me was debunked. I water seedlings everyday (only once a day ) and in pure coco (perlite or any amendments can decrease or increase cocos CEC and its exceptional buffering capabilities thats why Its easier for me to leave it alone)too and have not run into one plant that has died doing it like that.
Good post. Coco is definitely something you have to learn to work with, soil growing habits just won't cut it.
Just over 2 weeks
Theres a saying in coco Ive come to understand "Coco is a hydroponic medium. Treat it like soil and you will get soil results. Treat it like a hydroponic medium and you will get fast grow."
Yep. Go to this thread and read my posts https://www.rollitup.org/t/first-time-with-coco-seedlings-looking-rough-high-res-picks.977820/
Sounds about right. I finally put all the pieces together regarding growing in coco just this year. I tried using it years ago but treated it like soil, everything was great for a while, but then it all went to shit. I knew I was doing something wrong, I just didn't know what it was...that's so frustrating.
