The Soil Makers The Soil Makers - Aqueous Dry 4oz
Aqueous Dry is a nutrient-binding, water-uptake booster designed for growth-focused home gardeners, containers, raised beds, and hydroponic systems. This premium blend combines humic acid, kelp extract, yucca extract, and a powerful 5:2 formula to enhance nutrient chelation and maximize water absorption. By promoting mineral availability and improving how water moves through the root zone, Aqueous Dry helps plants access essential nutrients more efficiently, supporting stronger growth and healthier yields. Key plant-friendly science in every sip Yucca extract acts as a natural surfactant. By lowering surface tension, it helps distribute water and nutrients more evenly through media, reduces plant stress from drought, heat, and salinity, and supports a robust soil ecosystem by feeding beneficial microbes. Humic acid binds minerals into organic forms plants can uptake, boosting nutrient efficiency and soil health. It also improves water infiltration and helps safeguard roots against toxins, contributing to steadier growth in challenging growing conditions. Kelp extract provides trace minerals and growth-promoting compounds that support vigorous root development and resilient above-ground growth, working in harmony with the humates and yucca to maximize nutrient accessibility. With a balanced 5:2 formula, Aqueous Dry is designed to optimize how nutrients are bound and released in the rooting zone, helping plants take full advantage of every feeding. Size and usage: The 4 oz pouch is a compact, concentrated solution designed for multiple feedings. Typical usage is 1/2 teaspoon per gallon of water. Suitable for hydroponics, soil, and soilless mixes. Pair Aqueous Dry with your regular feeding schedule to boost nutrient delivery and plant vitality.

Flying Skull Flying Skull Elite Grow - 40LB
Elite Grow is one part of Flying Skull's three-part Elite base: Elite Micro, Elite Grow and Elite Bloom. The line is highly soluble, non-organic and particulate-free, which Flying Skull notes matters in hydroponic systems such as deep water culture, and it is formulated to deliver nutrients at lower EC/PPM levels. Elite Grow supplies nitrogen and calcium, and it is used in both the grow and bloom recipes. This listing is the 40 lb size.Guaranteed analysis (18-0-0) Total nitrogen (N): 18.00% (14.50% nitrate nitrogen, 3.50% urea nitrogen) Calcium (Ca): 16.00% Mixing (per gallon of water) Basic grow: 1/2 level tsp Elite Micro and 1/2 level tsp Elite Grow. For lettuce, herbs and delicate plants, use 1/4 tsp of each. Basic bloom: 1/2 level tsp Elite Micro, 1/4 level tsp Elite Grow and 1/4 level tsp Elite Bloom. Feed targets: hydroponic and soilless 300-400 ppm (0.6-0.8 EC) in vegetation and 450-600 ppm (0.9-1.2 EC) in bloom; soil 400-500 ppm (0.8-1.0 EC); lettuce and shade plants 200-300 ppm (0.4-0.6 EC). pH: soil 6.4-7.0, hydro 5.8-6.5. Good to know Never mix Elite Micro, Grow and Bloom together in concentrate. Add each one to the main tank separately. You can dissolve the powder in a little water first (Flying Skull's example: 10 tsp in 2 cups of water). Flying Skull says 1 lb each of Elite Micro, Grow and Bloom makes up to 220 gallons of nutrient for large, full-sun plants, or 440 gallons for shade plants such as lettuce.

Flying Skull Flying Skull Elite Grow - 9.25LB
To start using the Flying Skull plant food line you will need these 5 basics products: Elite Micro, Elite Grow, Elite Bloom, Z7 and Essential Flora Extract. We recommend the use of On Schedule for enhanced production. Those growers who include the On Schedule are very happy they added it to their application regimen. We also recommend the use of our USB (Ultimate Seaweed Blend) at ¼ to ½ ml per gallon of water.The Flying Skull Elite plant food line is a highly soluble nutrient. It was formulated to deliver high quality soluble nutrients to plants at lower EC/PPM levels (you use 2-3 times less than other brands). While formulated for production growing areas the Elite line of nutrients do very well for hobby growers too! True lab quality growth in production areas can be achieved when using top feed to waste grow systems and Flying Skull's ECWAM method of nutrient administration.There are three parts that comprise the basic formula: Elite Micro, Elite Grow and Elite Bloom. In most cases the grower will find that by simply following the feeding schedule, plant growth will be excellent. However, the way in which these three formulas were created gives the grower the ability to easily modify the basic formula for his particular plants.The basic three part formula (Elite Micro, Elite Grow and Elite Bloom) is non organic and is particulate free. This is important to growers who use hydroponic systems like Deep Water Culture, since inanimate slime (stemming from organic particulate) is the leading cause of plant death and system failure in these systems. All of the other products are used at very low doses because of their ultra-strength. Each product has is very low particulate when used at recommended rates.It is how you modify the amounts of Elite Micro, Elite Grow and Elite Bloom that pushes your plants from vegetation growth into bloom growth. This concept keeps the grower from having to purchase multiple products that virtually do the same thing. In other words, Flying Skull is formulated in such a manner that it costs less to obtain superior plant growth and consistent harvests.All three parts of the main plant food (Elite Micro, Elite Grow and Elite Bloom) are used in the first week or two of plant growth. While the plants are in vegetation mode the extra phosphorous and potassium from the Elite Bloom invigorates the roots and pushes them into growing strong. 7- 14 days after being placed into the vegetation area, Elite Bloom is removed from the feed and only Elite Micro and Elite Grow are used.A week before switching to the bloom 12/12 lighting cycle, all three plant foods (Elite Micro, Elite Grow and Elite Bloom) are used again. The extra phosphorous and potassium helps to build enhanced bud and blooms. As you can see, you can do a lot with only three main plant foods!In the last week of flowering and into harvest, only Z7 and Essential Flora Extract are used.How much nutrient does it make?9.25 pounds of Elite Micro, Elite Grow and Elite Bloom will make up to 2,035 gallons of nutrient for large, full-sun plants and 4,070 gallons for shade plants like lettuce. Use Z7, Essential Flora Extract and On Schedule for enhanced and consistent growth rates.What is the cost to make a gallon of nutrient?9.25 Pound Jar: (Calculated at 1/2 teaspoon per gallon of water)9.25 pound of Elite Micro (MSRP $73.95) makes 2,035 gallons of nutrient for 3.6 cents per gallon. 9.25 pound of Elite Grow (MSRP $56.95) makes 2,035 gallons of nutrient for 2.8 cents per gallon. 9.25 pound of Elite Bloom (MSRP $58.95) makes 2,035 gallons of nutrient for 2.9 cents per gallon.Note: The costs and gallon are subject to the recipe used. The end of the year cost per gallon will more than likely be less than those stated above.Only increase the strength of the nutrient if you are absolutely sure you need to. Leaf abnormalities like tip burn, leaf curl, very dark green, necrotic margins and a leather like feel can be attributed to over feeding by either having the nutrient too strong initially or nutrient has built up in the root zone.
