Guys I am looking for the best strain for indoor marijuana growing. I have one 400 watt hps and i am going to grow in a hydroponic wick system. Here is what I would like... 1) The most important thing to me is getting the most bang for my buck. I want to get a high yield but also a very potent one. I know potency depends a lot on who you grow but what is a good strain that is potent and should have a high yield? Lastly is is worth it to buy feminized seeds? Is it 100% chance that the seeds will be female or more like 85-90?
