this will be my first adventure into growing my own plants, so you're going to have to talk in less slangy terms. What does "flowering from day 1" mean?start flowering from day 1 and go with something that flowers in under 8 weeks.
^^^ThisUsually people do vegetation for atleast a few weeks with lights on 24 hours a day or on 18 hours and off for 6 hours. If you start with 12 hours on and 12 hours off then youll cut a few weeks off your harvest time. Your yield will suffer though and plants wont get as big.
You could start with clones too if you wanna speed it up a bit and dont want to wait for seeds to germinate and all that crap.
