I've just started cloning and I have a humidity dome that has adjustible air vents on it, what position should i have them in?
For the first 2 days have them completely closed. Take the top off for about 10 minutes twice a day to foliar feed them. After the first two days you can open one of them to be completely open (still spraying twice a day with the top off). After the first week you can leave the top off completely (still spraying 2-3 times daily until roots show). Good Luck!
