Second time growing, first time in greenhouse, any pointers?

i have one strong 4 week old female snow white plant i grew from a seed and have a few other germinated seeds. i am using the older plant as a motherplant for clones, and also as a tester so i dont screw the others up. i am using soil, mixed with peat moss. i plant on topping the mother, and running her limbs along a screen as to promote more colas (as i have read) but also to make more spots for cuttings. problem is i have never ran a clone before. does the greenhouse act as a humidity dome or should i even have the clones in the greenhouse? :S Also i have liquid-gel root stimulator and was planning on using pure peat moss and compostable planting pots for the clones. yay or nay on this? i topped the plant this afternoon, maybe too soon but only time will tell. Anything else that good to known lets hear it.
