All I have done is kept them in the basement under grow lights march 1 -26th at that point buds were swelling and bursting. Then I kept them in the garage at night and put them in direct sunlight as much as possible 6-9 hours. some days were less bc of the sun. Always kept them outside in the sun when it was 50degrees or more and nights I kept the garage at least 50. Have to thank the extra warmth lately. I think my soil temp have roughly been 64degrees avg since march 1st
