When using a humidity dome to root clones, do you recommend a vented dome or sealed dome? I've heard a lot of people using a sealed dome that they mist (plant and dome) and then they open the dome once or twice a day to introduce new air. Then I've also seen a lot of the domes you can buy come with vent slots/holes already cut. What do you guys recommend on this? Which is better?
Also - should there be a 24 hour dark period after planting clones in rooting medium before putting light on them, or should they get light right away? This seems to be another one that opionions differ on.
Any help is appreciated. Thx.
