also.. how do you like growing in straight pearlite? my coco pearlite mix is roughly half and half and I love it.. seed I started straight in the mix and fed 250ppm until it had some true leaves, than 500ppm currently.. and crap, it's the fastest I've ever seen for this stage of development.. dwc you have a waiting period until it puts down roots.. this just takes off from the start.

I don't like how much gnats like it though.. you have that problem with pearlite?
