My brother has been growing for >20 years and has run almost every major nutrient brand out there. When he came across DaKine a few years back he asked me to give them a shot. I was reluctant at first, and was happy with my output. I finally relented and have Dakine a try. My output nearly doubled. The plants are healthier and the grows are easier. Solid weights make life so much easier than worrying about ml/gallon measurements. I’ll never look back and recommend them to anyone I come across who grows.
