Hi! I just recently purchased a 1500 gram Female Lemon blast that I was hoping to cross with my 750 gram spider ball. is it too late to start? and if so what would the recommended first steps be? this will be my first go at it and something i want to continue in the future. would it be better to just keep the too together and start to drop the temperature at night or would i be better to do that 3-4 weeks separated and than start to introduce? any help is appreciated!
