I was just about to add, if you are going to buy seeds, check our sponsors. Including BOG Seeds, who is also a long time member here and the old overgrow forum. We just had a group buy through him, but his prices are nice to begin with and you can email him directly. His seeds are in several online seed banks, but why bother when you know the source is here!
Oh right, There is work being done to get group buys to be a regular thing. The GG4 group buy is now 30 seeds for $50
