First grow questions

Hi, I'm preparing for my first grow and really want to get some Jack Herer. I've been eyeing this store because it's more affordable but i don't know if it is a good source: https://www.marijuanaseedshop.com/seeds/jack-herer-seeds

Also, I've seen some stores with variations of Jack Herer but cheaper, like: http://www.worldwide-marijuana-seeds.com/products/spliff-jack-f1

How different would be the high compared to the original?

I've also been eyeing some white widow, it's a strain that I haven't tried yet but I hear good things about it, does the indica side hits you too hard? I'm looking for a more energetic, creative, happy and uplifting strain that still lets you do creative work, any suggestion for some nice and decently priced strain seeds that follow that?

Read and research!! You have lots to do.

Start with inexpensive seeds. You'll likely need to get a few grows under your belt before you get close to maximizing genetic potential anyway. Have fun and enjoy!
