So how much did it cost all up ?
i cant remember exactly ( was at the start of the year) but i believe in the $200-250 range after conversion including postage.
its a powder which i like (i dont like paying for water) and i mix it up in 1L stock solution (only because i only use 2L bottles for watering and its a little hard to dose the powder in small amounts)
i quite like it and has cut my base nutrient cost dramatically (i would have easily gone through 2L of my old base which is $180 in the same time ive used 500-600g of MC).
only thing ive been running with it is magnesium sulfate (epsom salts) and mono potassium phosphate as a pk booster (and thats only recent, first couple of crops without it where fine with just the base nutrients)
