To get the most out of premium quality fertilisers you need to raise your plants' metabolic rate. After all, you don't get any benefit from top quality food when its stored in the larder. You have to eat it!
B-52 fertiliser booster essentially increases the appetite of your plants - giving them a super boost of energy which, in turn, increases nutrient uptake.
Truly staggering increases in growth and yield are achieved totally through naturally occurring hormones and vitamins - but your plants can't get this sort of boost from anywhere eLe. Use with soil or hydroponics, ideally throughout the plant lifecycle.
