growing from bagseed or any seed is a roll of the dice, you never know what you will end up with, it is ideal to get seeds from a seedbank if your going to grow from seeds because the chances you are pulling from a good gene pool are much greater. If you must grow from seed understand you roll the dice, take your best plants from seed and clone them or have someone else do this part for you. If your only growing a few plants keep in mind you are taking quite a gamble when you grow from seed, growing from seed is starting from scratch understand this comitment you are making can be long and bumpy, if you have the option I suggest you start from a clone so you know it has already been chosen as a winner at least from someone. There is much more at risk then hermaphrodites when you grow from seed you can have greater genetic problems to tackle that are a lot more serious then pollen sacks.
from bagseed every trait is on the line - from clone this has already been controlled - Yield, Potency, Flavor, Aroma, Appearance in the final product and also the health of the plant is at stake from a grow which is not controlled genetically - it is not unlikely you will need to grow hundreds of plants from one seedstock until you find the real winners in what you are looking for that works in your environment.
This is the key to growing top quality cannabis, often overlooked by many and sometimes people never learn, when you read online about marijuana any guide they assume you grow from clone, read up on scientific literature about cannabis before you trust what you read on forums, the forums information at best supplemental and doesn't really grasp the whole spectrum.
