Congratulations on finding GC. Can't wait to see the pics.
Your lights feetprints will be alright. Maybe could use a 400 in place of that 250, but it sounds like you got it divided up. It wont really equal 850 watts. Just one footprint of 600watts and another of 250watts. I take it that the 250 is over a 3x4 space and the 600 is over a 4x4 space? You are using MH which is great for veg but not for budding. I did not even know that they made a 600watt MH ballast. Are you using a conversion lamp? MAybe it is an HPS and you typed wrong?
If your 250 is MH I would split the area into 2 areas to get your SOG perpetual harvest going. Use the 250watt MH to keep moms and root clones, and use 600watts of HPS to flower.
SOG will only work with a mom chamber seperate from the flower chamber, and the ability to clone.
Good luck with the setup. Peace
