High there and welcome to RIU.
The more you look at seed banks and the more reviews and descriptions you read, the more you will start thinking, "Doesn't anyone write a poor review?" LOL
The fact is, no they won't. You'll find varying info here, but writing the
seed bank an email is a good place to start.
My experience is Attitude delivered what I ordered in 9 days from purchase. Nirvana is a good one, but it might take longer. High Grade
seeds took almost a month and the order was incorrect. Single
seed bank may be a bit higher, but their delivery is good.
Since you are currently living in an apartment and haven't started a grow...do A LOT of research when it comes to lighting, ventilation, and before you buy anything...establish a budget and expect to go waaaay over. That's the best info I can give you right now. We're all here to help, we'll most of us are. If you run into a troll or flamer, ignore them and keep asking questions.
Good luck!
