Description
Root+ by Metrop is a root stimulant that accelerates root growth in your cannabis plants. It’s used at the start of the growth period in order to increase the speed and growth capacity in your plants. It’s used after every transplant so that your plants can shoot back to normal after such a stressful process. It should be switched out for Amino Xtrem at the start of the flowering period.
This product is capable of giving your plants the ability to absorb many more nutrients, so you’ll need to increase the amount of nutrients you feed them within order to avoid NPK deficiencies. We recommend using minimum doses when grown indoors as it causes your plants to grow quite large.
The ingredients in this formula are designed to be absorbed and easily dissolved, so it can be used in automatic watering systems and in any sort of substrate including hydroponics and aeroponics, as well as soil and Canna Coco Professional Plus 50L.
We recommend alternating between water and nutrient solutions when watering so that you don’t end up over-fertilizing and accumulating salts in the substrate. This could cause blockage in your roots, causing your plants to stop feeding.
You can check out Metrop’s full growing chart in order to give your plants a wonderfully balanced diet using their other fertilizers and additives.

A friend recommended it to me. I would like to know if this will be enough for about 4 plants grown in coco. I'm a bit lost with my first grow and would like to have a bit of peace of mind.
Translated from Spanish
Me lo recomendó un amigo. Me gustaría saber si esto será suficiente para unas 4 plantas cultivadas en coco. Ando algo perdido con mi primer cultivo y me gustaría quedarme un poco más tranquilo.

Does Root+ work well for fresh cuttings or only for growth?
Translated from Spanish
¿El Root+ funciona bien para esquejes recién hechos o solo para crecimiento?

Hey guys, I've been using the Metrop range for 4 years and honestly I wouldn't switch for anything, after several years testing all kinds of nutrients, for my taste this is the king. I'm talking about an outdoor grow, indoors you have to be very careful with the amount because you can burn them easily
Translated from Spanish
Buenas compis yo llevo 4 años usando la gama metrop y la verdad q ya no cambio por nada, después de varios años probando todo tipo de abonos para mí gusto el rey es este. Hablo de un cultivo exterior, en indoor tienes q tener mucho cuidado con la cantidad pq las puedes quemar con facilidad
