humidity vs air
i've put my germinated seeds into the small rockwool cubes and they are in my propagator.the humidity is nice and high but no fresh air is getting in. there is an opening at the top which i can open but this reduces the humidity. im just wondering when exactly the seedlings start to require air. i want to keep the humidity high but also provude fresh air to them.
also what temperature should i maintain them at from now until i transplant them into the large cubes?
As soon as they have popped the surface they need both humidity and fresh air, so don't over-do the propagator. I always manage an almost 100% success rate without using a propagator by just popping some zip bags loosely over the top of the pot. It keeps in some humidity, but also lets air in, and seems to work almost every time.
Temps should be between 20-27C, slightly warmer during the day than the night. Soil temps shouldn't drop below about 16C.

i cant remember where i read it but i definitely read that they initially need a high humidity. it was in a book so i will assume it is correct. i think it was jorge cervantes bibleOriginally Posted by scroglodyte
No Scrog is correct. Clones need humidity but seedlings certainly dont. As soon as my seeds germinate they go into rockwoll and directly into the net pots. No extra steps needed.
