As far as the question about seed banks...Ive had great experience with Nirvana seed bank. Nirvanashop.com it ships from europe and I found thier seeds are a great price compared to other sites. They have alot to choose from and I would suggest that you pick feminized seeds.All the work ur doing with the bag seeds and you dont even know if they are gonna be female. Prob in 3 weeks you could put them into flowering and then less then 2 weeks you should be able to tell if they are female. I plan on ordering from herbies headshop next but they look to be a little on the pricey side.
Ive seen people talk trash about Nirvanas genetics but my girls look great. Ur plants also looked pretty healthy. You should be proud you got this far...I feel like most people dont even make it as far as you have.
