With all the money you had to invest. You could have gone hydro and still had more left over. Soil is a pain in the ass, especially ph'ing. I know I'm going to get stuff for saying it, but you should have gone hydroponics, I promise you its more fun and more automation involved. With soil, no offense, your more bound to screw up. This is only my opinion. You has all that money, note you have a soil set up, not hating, but you should have gone hydro. I started my hydro setup with 250, imagine if I had 850+. Wow, id be superman. Again, this is all my opinion. Hydro is the best. Again, in my opinion. You look all set though, either way you're going to be smoking some in 8-12 weeks.
