Magnesium( Mg) is very important for plants as it is used in chlorophyll formation, protein synthesis and all energy transformations. In animals Magnesium is important in the metabolism of carbohydrates, lipids (fats), proteins, in nerve activity and muscle contraction. Magnesium Sulfate is used as a soluble salt for outdoor and glasshouse fertigation programs as well as a foliar fertilizer for application to crops to help overcome magnesium deficiencies.

BuildASoil Craft Blend started with a big workshop full of the best and cleanest soil amendments available. I quickly became spoiled and would use all of the BuildASoil ingredients together and in different combinations that aren't available here online. After discussing re-amending with a buddy and also Nutrient Tea Brewing he mentioned that I should combine every nutrient that we have into a fertilizer pack of the cleanest ingredients for everyone to use.
Oyster Shell Flour is a high quality soil conditioner which consists of 96% calcium carbonate and many micronutrients, Oyster Shell Flour provides a long-lasting, steady release of nutrients to help regulate pH levels, improve fertilizer uptake, promote healthy cellular structure and enhance soil tilth. Oyster Shell is also helpful in creating more active habitats for soil microbes in compost piles and worm bins.

Back Country Blend Grow is a low-frequency application-rate granular nutrient system designed for the outdoor grower during the vegetative stage of growth. It can easily be either applied to soil or top-dressed, so you can feed less often with great results. Back Country Blend Grow contains a full spectrum of nitrogen (N), phosphorus (P), potassium (K), and calcium (Ca) measured specifically for the vegetative stage of growth. Nitrogen is vital as it plays a major role in a plant's ability to perform photosynthesis. It also promotes vigorous plant growth and dark green foliage. The granular form allows for a controlled release of nutrients to the plant to avoid burning and overfeeding.Directions for use:Apply Backcountry Blend Grow at a rate of 1-2 tsp per 2 gallon of grow media or 2 feet of plant height on week 1 and week 4 during the vegetative stage, or every 4 weeks as needed. Cease use 2 weeks prior to flower.
Speak your plant's language! BuildASoil proudly welcomes the famous Jay Plantspeaker to our LEGEND SERIES to help you communicate with your plants in a truly meaningful way. Maybe your plants won't speak back, but they will show you they are happy. Using saponins found in Quillaja Extract Powder for your garden is an absolute game changer. This natural wetting agent makes water 'wetter' and foamy allowing for even spread. Made from the organic Quillaja (Q-Ya-Ha) Saponaria Tree, we can't speak highly enough of this plant extracted source of Saponins.

Mykos Wettable Powder is refined to provide an effective inoculant that may be injected through a sprayer, applied in hydroponic reservoirs, and used as a seed or cloning treatment. It is a fast-growing, beneficial fungi that connects many of the beneficial microbes in soil and hydroponic media to host plants. This symbiotic relationship increases the supply of nutrients to plants, increasing the availability of both moisture and most of the fundamental elements required for plant growth. Greater nutrient availability leads to a bounty of healthier bigger plants and bumper crops.Benefits:Faster GerminationInoculation of All New RootsIncreases GrowthHealthier Root DevelopmentLarger YieldsMore Nutrient-Dense HarvestsSolubility
