Using Reefertilizer Start to Build a Healthy Root System
Reefertilizer Start can be used 3 different ways depending on your growing style.
No matter which way you choose to use it, Reefertilizer Start will inoculate your soil with mycorrhizae and provide beneficial micro organisms.

Three ways to use Reefertilizer Start
Starter Soil

Mix Reefertilizer Start into some potting soil to make your own super starter soil for seeds and cuttings in small pots.
Transplant Inoculant

Use Reefertilizer start when you transplant into a larger pot. About 3 scoops per hole should do the trick.
Top Dressing

Apply Reefertilizer Start as a top dressing. Apply 3 scoops around the base of your plant and water normally. Great option for autoflowers.
Using Reefertilizer Grow and Bloom for Optimum Growth
Reefertilizer Grow and Bloom are both water soluble powder fertilizers. We recommend feeding your plants once a week and water them if needed when growing in soil. If you’re growing in auto pots or hydroponics you will need to adjust your reservoir concentration accordingly.
Tap water is fine to mix with Reefertilizer and use with your plants, but the quality of water may differ from place to place. Using a pH pen will tell you if your tap water overly acidic/basic. Cannabis grown in soil enjoys a pH of around 6 which allows roots to metabolize the most nutrients possible.
