This osmosis filter will enable you to produce between 100 and 190L of water free of chlorine and salts, which with an addition of calcium and magnesium will be the best water for growing cannabis plants indoors or outdoors.

Keep in mind, osmotized water cannot be applied directly to the plants. It needs to be reconstituted with a calcium and magnesium supplement until it reaches 0.4 mS. The ratio is 2/3 calcium to 1/3 magnesium. Products like Canna's CalMag Agent, BAC Calmag 2.0, Grotek's Cal-Max are necessary to reconstitute the osmotized water, just gradually add the product until the EC meter reads 0.4mS.

La Huerta's Opinion

Keep in mind that these osmosis systems waste more than 50% of the water they filter. You can make use of the leftover water by using it to clean pots, your growing area, for the toilet tank, and so on.

If you’re looking for an osmosis filter with a higher daily yield, consider the reverse osmosis filter GrowMax Water's Power Grow 500, which can produce up to 500 liters per day.
