Your best bet is to check the Grow Logs for ideas. Put some effort into researching what other med patients are using for their ailments and symptoms, and go from there. I prefer indicas and indica dominates (in soil) for inducing my appetite, relieving insomnia, and joint pain, (chronic hep-c) but your needs may vary. Indica's generally finish quicker, too.

Choose your vendor carefully. Check into their reputation both here and on Google, as some vendors seem to be developing a bad rep. Sometimes a disgrunteled costomer will complain, but usually you can get a feel for the cannabis communities thoughts on their quality and service.

Trainwreck is fine indoors.

As for recommending a vendor...try one of our sponsors. That's what they're spending all that money on banner ads for. But, I haven't bought seeds in around 10 years so have no personal experience to share.

Good luck.
