Mills presents C4, a flowering stimulator in liquid format of bio-mineral origin that helps to achieve bigger and heavier buds in indoor and outdoor cultivation of marijuana plants. The secret of this product is its effective formulation, which allows a rapid assimilation of nutrients as do mineral fertilizers, while enhancing the flavor and aroma thanks to its organic components.

How is the Mills C4 stimulator used?

There are 2 ways to use C4, combined with Sugar Rush or Ultimate PK, so I am going to show you the 2 ways to use it. If you use Ultimate PK you just have to add C4 for 4 weeks, from the third to the sixth of the flowering phase, starting with a dose of 0.5 ml / l, the following week 1 ml / l, the next 1.5 ml / l, and the last one is lowered to 1 ml / l again.

On the other hand, if you use this product combined with Sugar Rush, it must be applied from the third week of flowering until the final root wash, starting with 0.5 ml / l, increasing the fourth week to 1 ml / l , the fifth week we continue to increase to 2.5 ml / l which we repeat the sixth week, and then we lower the dose to 2 ml / l during the last 2 weeks before washing the roots prior to harvest.

It is important to also combine C4 with Basis A and B fertilizers, and a weekly application of Vitalize is recommended to achieve the most satisfactory results. Remember to shake all the products well before use, and keep them in a cool place away from light. Both C4 and the rest of the products in the Mills range are suitable for any irrigation system, whether in soil, coco, or hydroponics.
