i ve always used miracle grow and my mates use westlands, 2 x 50 litre bags for a tenner from b&q. only issue with miracle gro is that its got slow release nutes and although i've had no problems at all i know sum people complain about nute burn( i never added any nutes for first 3 to 4 weeks though).70% miracle grow, 20% perlite, 5% vermiculite.total cost under £20. eventually bio bizz nutes, gro and bloom, treacle at the last few weeks of flower, all in ten litre tubs, under 1000 hps for flower. water roughly 3 times a week(aroound 2.5 to 3 litre per water). pulled 23 oz from 6 plants, although one plant was moved halfway thru flower due to possible hermieing and put under 400 watt hps on it own.
