Simply soak the wool in dechlorinated water at the desired PH for 24 hours. After 24 of soaking your free to pop a seed in there, take some cuttings, or do a transplant what ever it is that you are planning on doing with the wool ☺️

Inside of seed stuck on cotyledon leaves keeping them together
Has anyone ever had the inside of the seed stay on and keep the two cotyledon leaves together? The outer hard shell has come off. I've been spraying it to try and soak it off but it's quite hard. Anyone ever successfully deal with this or will it just pop off on its own?

Blocking roots in biodegradable jars ?
Can I leave them for another week or so in the biodegradable jars? Or does it risk blocking the roots? I can't imagine what size the roots are yet.

Seedling stretching: genetics or lack of light
Do some genetics stretch more than others as seedlings or is it always a case of not enough light? Pictures are 20 hours apart

Did I need to size up to larger rockwool cubes?
Geminated seeds in 1x1x1 rockwool cubes. End state is to be in 5 gallon buckets with 8" net pot and clay pebbles. I figured the roots are too small to reach all the way into water solution still so put small cubes into 4x4x4 rockwool. Did I need to use larger cubes?

Blätter gucken aus Samen ohne Stamm?
Ich habe 3 Purple Punch Samen gekauft. Eine hat eine es nicht geschafft nach 9 Tagen die Wurzeln aus dem Samen hinaus wachsen zu lassen. Aber diese hat bereits die zwei runden Blätter entwickelt ohne Stamm. Liegt das an der Qualität des Samens oder habe ich etwas nicht beachtet?

Germinated seeds not sprouted yet
I germinated 6 seeds that all after 4 days had cracked open and showed small tails. They were put in small pots with soil + perlite, soaked in ph 7 water. It’s been 6 days now since they went into soil and none have spouted. Wait more or disturb the soil to inspect the seeds?

How long to keep plastic covers over seedlings
How long does everyone keep the cover on their seedlings before exposing them to the flow of air via fans? Some people remove the covers as soon as they pop. Others keep them on for a couple of weeks. Let's start the conversation :)

Sprouting delay. How long do I wait? Are lights on and fans running important while waiting for germinated seeds to sprout? I lightly water the medium.
Germinated autos by paper towel method, & put them in soil 2 days ago. The still haven't sprouted out of the soil. How long should I wait? I'm trying to keep humidity between 60-70% and temperature 20-24C. The LEDS are on 18/6 and the fans are running for the pots. What do I do?
