How to Use Build a Soil Craft Blend

Brew Nutrient Teas 

Veg Through Flower, use 1/4 - 1 cup per 5 gallon bucket of water. One of the best ways to use Craft Blend is to brew nutrient teas, which are an excellent way to provide your plants with the nutrients they need in a form that is easy for them to absorb. Simply mix 1/4 to 1 cup of Craft Blend into a 5-gallon bucket of water, let it steep for ~30 hours, and then use it to water your plants.

Re-Amending Used Organic Soil

With BuildASoil Craft Blend, you can re-amend your used organic soil to give it a new lease on life. Simply mix 2-4 cups of Craft Blend per cubic foot of soil, and you'll be providing your plants with a complete range of essential nutrients.

Re-amending your soil with Craft Blend is an excellent way to reduce waste and save money. Rather than constantly buying new soil for each grow cycle, you can re-use your existing soil and simply add in the nutrients that your plants need. This also helps to maintain healthy soil ecology, as you are not constantly disrupting the natural balance of microorganisms in your soil.

Top Dress Your Plants

Looking for an easy way to give your plants a boost of nutrition without having to mix up a nutrient tea? Top dressing with BuildASoil Craft Blend is a simple and effective solution. Just sprinkle 1/4 to 1 cup of Craft Blend per plant on top of the soil and water it in. This method is especially effective for plants in their flowering stage, as it provides a slow release of nutrients that will support the plant's needs over time.

Craft Blend's unique blend of high-quality ingredients ensures that your plants will receive a full range of essential nutrients, including nitrogen, phosphorus, and potassium, as well as trace elements like calcium, magnesium, and sulfur. This makes it an excellent all-in-one solution for plants at any stage of their growth cycle.
