Reverend Clonie, 2 weeks prior to signing up to this forum I started my first grow and this is the soil mixture. 65% pro mix soil (completely sterilized),10% perlite(aeration),5% dersertsand,and 20% pottingsoil. In addition to all these I included a 9-6-6 npk valued Fox Farm bat gauno and worm casting fertilizer to my mix. I grew them under a 400w hps hortilux from seedling to finish. I did this because of my budget at the time but now i bought the growzilla reflector which can house two separate bulbs. I also bought a co2 injection system which should help. I've got four Crystal plants growing at about two weeks old and looking good. I am reluctant to experiment with different fertilizers since this one did fine but I am always open to sugestions.
