Seedleranswered grow question 2y ago HEY!
Don't worry about all the answers.
Thats a normal question for a beginner but it's really "over asked" and most people just roll their eyes, also you expect people to really state why its better with pro and con's and the list can be very detailed.
You are a beginner, stick with photoperiods. Look for the terps (smell taste) you like and grow that next.
If you want to try something new, go for autos but you need to inform yourself beforehand. Autos are like racing cars, super fun if you know how to handle. If not you drive off dealership and crash.
Photoperiods are always the safer option, because you can veg (vegetative phase) as long as you want and flip when YOU are rdy. Automatics flip when THEY are rdy, doesn't care what you do at all.
This means the environment for autos has to be perfect to really use the genetics. But also having a full grow and harvest with like 100g in 9 weeks total is pretty nice, thats why i love automatics!
good luck on your journey!
