Well here is my thoughts. If you got the money to spend, I teach you to use any median there is, from coco to Rw, to Current cultures $5000 UC system.. So if you want to buy a bag of coco and some 1 gal pots since your a newbie, because that fella up above that said you better have your game on with automatic watering in small pots, was dead on the head with that! So even tho I use 1/2 gal pots and water multiple times a day, 1 gal would be better for someone less skilled, or lapsing a timer controlled dtw system..You got to really get the run off correct with Sun tea feeding and routine checks of the coco for salt build up when your in small 1/2 gal pots...
So if you got the money and dont mind get slapped around by learning another new median, then by all means, get er done.
And your cns17 and +life will work perfectly with your coco... im kinda funny about my coco as I like course coco, with no peralite, and I use House & Garden from the Netherlands, but I just dont care for the brick stuff that looks like a kilo of 80's brown Mexican dirt weed.
