Benefits of Applying MR-1 by Metrop to Grows
When buying quality nutrients such as organic nutrients that you’ll need to let sit in a tank for a while, there’s not very many options – MR-1 by Metrop is the perfect growth fertilizer that is incredibly rich in nutrients, so you need incredibly small dosages.
This product is made up of algae and plant extracts and it has the perfect formula and nutrient combination to keep your plants healthy without overdoing it. It also keeps your water’s EC levels stabilized, so you shouldn’t need to worry about that, however you may need to adjust the pH ever so slightly.
We recommend using this product alongside the rest of Metrop’s nutrient range in order to get the best possible results. Consult their simple growing chart to find out what the perfect diet is for your cannabis plants.

- Measure the EC in your water when using Metrop products.
