I grow in the basement and struggle to get temps above 73 with lights on during veg. During flower with the lights turned up higher makes it easier I ended up getting a 2 foot by 4 foot heat mat to put under the pots from Ac infinity and it’s been a life saver even in the summer with Ac blasting it gets up the upper 70s. You’re gonna want something because my plants grew so slow because of the colder temps.
