ya i have a small fan inside and a large fan blowing air from my room into the grow room.
i think the key to have a good clone is to make the 45 cut good or even a 60 degree.
then make sure they get at least 4 hours of rest a night dont put them into 24/7
my clones arent wilting when i cut them then give them an imediant 3 hours of dark
after that put them into 18/6 or 20/4 and mist the dome as much as u can with a
low heating mat underneath. and its better to have the heating mat a few inches underneath the dome so its just warmth. i rest my dome on dvd cases to give it the right height.
using this i got my first successful batch of clones
