The MG soil will work fine, but later on down the road you should consider making your own organic soil mix. You'll have much better control over nutrients and soil consistency.

I would, however, recommend that you ditch the halogens before you grow anything and switch them out for CFLs. Halogens don't put out near enough useful light for the amount of heat they put out. Fluorescents burn much cooler and have color spectrum's that are much more accommodating for plant life. I unfortunately can't give more advice about color spectrum's for CFL-only grows, because I've never done one. But they're very efficient when done right, so wait for a little more advice about it before you purchase your bulbs.

Lastly, make sure ventilation is covered in-depth when you begin your grow. You won't have to worry about heat as much as if you were using an HID, but air circulation is still very important. Plants grow terribly in stagnant air. Good luck with it! :jointsmile:
