dont put the plant in the dark for 36 hours first. that will stress the hell out of it big time. just put your light on a 12 hours on and 12 hours off timer and dont change it once you set it. dont change the amount of hours and dont change what hours either. its very important that you stick with your light cycles you choose.
as for cloning i would try to make a DWC cloner. check youtube for vids on how to make them. or you could go with rockwool cubes and some rooting gel in a very shallow dish of water. both methods have always worked good for me.
btw ide really look into getting a small HID light like a 250 watt HPS for your main grow too. your not going to get very far with the light you got. good luck with your grow!
