A lot of soils out there for growing i read that 12/12/12 or 20/20/20 for NPK is best although they also say a higher N value for veg state & a higher P value for flower. Miracle grow is most the common in uk which tells you npk values, i have looked around the likes of B&Q & Focus but all the bags i have read do not state npk values which leaves me a bit confused. Which soils that can be found locally are used by most growers?. all other soils i have heard of are of american variety, and therefor are of no use to us, Any help is much appreciated.
