You have to remember seeds are a shitty situation if you're looking for a specific trait. Check out this chart which shows you how a given seed may turn out. You may get a seed and it may turn out perfectly, but there is a luck factor in place... check this out
I'm a natural born skeptic, so I dont believe this chart entirely, but I do think it has its merit
What I'm saying is, if you're growing from seed you need to read where is going before it gets there. If you're growing Durban Poison you wont veg for 2 months etc.. One way to take control early is to SCROG. It's a super easy training method, but there are down sides. You cant move your plants with a scrog. If you are growing in a closet and you have to take the plants to the bathtub to water, a SCROG isnt going to work.
You will find "your" way in this crazy hobby. Remember to keep it simple, grow for quality not quantity, read and talk to people you trust. You may find people on here that just nod their head in agreement when they really dont know.
You're gonna do well. You ask good questions
