Most people use the HP

The BX line has vermiculite in it which holds more moisture and takes longer to dry out which can cause problems in some plants.

I knew I should have posted a thread on this instead of pm'ing him some odd days ago, but, quoted:
"I use BX for seedlings and HP when I transplant up to 3 gallon pots. BX holds a little more water than HP. BX is good for MH/HPS lights where the heat from the lights dry things out faster. HP is good for CFL, T5 and LED. I germ under MH and flower under LED. HP is fine under HPS, you just have to water about a day sooner."

Yep. I've found HP dried out a bit fast for seedlings so use BX but then HP for my final pots. Under the added heat of HPS light the added moisture holding capabilities of BX is good but it tends to stay wet too long under my LEDs.
