So it's pretty typical that root establishment is a must before even opening the vents on the dome and then from there continue to aclclimatize them slowly without spraying plant foliage directly, only the inside of the hood.

I've heard before that a good rule of thumb for thinking about opening vents is five roots emerging from your rockwool. Do you belive that this saying has weight, if not when would you consider true root prodution? At the begining of seeing rooting sights along the clone, or roots emerging from the rooting medium.

Again great posts to this thread so far, I'm sure that with this info I wont have any more spoiled experiences.
