Good to hear you are trying out growing some good Bagseed.
Amsterdam strains are just great and those boys put allot of time in effort into them.
However, they are way too inbred in my opinion and the best smoke I have ever had came from a Bag of Schwag that I grew.
It is like a Treasure chest with Bagseed and when you wind up with that one rare and crazy pure female, it is best to keep some clones just to be sure, that you do not regret loosing her.....Been there and done that.
That is another reason that I like to do 12 and 12 from seed, when working with these Trees now and especially Bagseed.
By starting out a Bagseed on 12 and 12, you are able in time and with a good eye, to tell in just a few weeks, wich way the Tree seems to be going as far as it's sex and smell and Trichome production and internode lengths, ect. ect.
It cuts down the time invested in a Tree as far as not having to give it Veg time also and it wind up being a male or Hermie.
Once I find what I belive to be a " Choice Female Bagseed " from the group I will start on 12 and 12, I simply place her back onto 16 to 18hrs a day and let her or them Re-Vegetate to the size I want and then slap them right back into flowering, to reap the real rewards of my efforts in the end.
When they go back into Re-Veg my brother, they will take on a branchy and pretty crazy look at times, but it does not harm them or the medicine and I think they are really gorgeous when they look different from Re-Vegging.
Good way to segregate good Bagseed from more inferior and once you get a few good ones........anything from amsterdam is just Novelty,LOL.
Be Blessed,
