after another think.. i thought i might go with 20/4 on the lights for veg.. so they only have 4 hours in the cold.. n just b4 i flower them i need to go to my local hydro store for perlite light hangers and such so i think i will pick up a little heater then.. so when i flower them i can have the heater on the 12hour dark period so they aint cold.. i hope with a bit of love they will be ok in the cold for 4 hours a day.. then when i flower them i bet there will be no stopping them hehe..
