Rox contains many pgr's (Plant growth regulators) which no other bloom stimulators or boosters contain..... Hence it does what no other stim or booster can!!

This is a 0.25l bottle - you only use it for 7-10 days so it goes a long way.

Please note: this is for 0.25l bottle which will come plain as we pour it out of a 1l bottle, for instructions please see this advert.

Instructions: add to your regular flowering nutrient & additives for 7-10 days only around weeks 3-4 of flowering.  Hydro use 3ml/l, soil & coco use 5ml/l
