  • Sale -34% Aptus - Ecozen Hydroponic Center Aptus 100ML

    Aptus - Ecozen

    Ecozen is a powerful blend of enzymes that keep the root surface clean, assist in breaking down decaying organic matter, and displace salt buildup from the planting medium.

This helps to stabilize EC in the medium and improves the plant’s natural ability to absorb more nutrients while avoiding fertilizer salt build up that can cause antagonism, lock up and conditions enabling pathogen related problems in the root system. Directions for use: Use for the entire vegetative and bloom cycles at the rate of 1 ml per gallon Flush at the end of every week and end of cycle with just water at the rate of 2 ml per gallon

Calcium also increases the cation exchange capacity of soils, making nutrients more available to microbial activity and ultimately to the plant. The addition of Herculean Harvest to any nutrient line will increase size, aroma and flavor of the plants' fruit. It also aides in washing salt from a potting soil or soilless medium, and can be used as part of a soil flush solution.

Instead of chemical chelates like EDTA, Calyx Magnum utilizes plant based amino acids as a chelating agent. This means that Calyx Magnum is biodegradable, making it a better choice for the conscious and sustainable minded gardener.   Calcium plays an important role in the development of plant tissues, root systems, and disease resistance. Magnesium is an essential mineral used in the process of producing chlorophyll, which is in turn important for the process of photosynthesis. Magnesium is also critical for the uptake and migration of phosphorous in plants, making it a major mineral needed for blooming and flowering varieties of plants.   Guaranteed Analysis Total Nitrogen (N)..............................................................2.00% 2% Nitrate Nitrogen Calcium (Ca).....................................................................3.40% Magnesium (Mg)................................................................1.40% 1.40% Water Soluble Magnesium Iron (Fe)...........................................................................0.10%     DERIVED FROM: Calcium Nitrate, Calcium Gluconate, Magnesium Nitrate, and Ferrous Sulfate.Directions: Calyx Magnum can be applied to all crops including hydroponics, vegetable crops, row crops, field crops, trees, vines, ornamentals, gardens and landscaping.

    Nectar for the Gods Persephone's Palate

    Persephone's Palate is Nectar of the Gods answer to the use of molasses in a feeding regiment. The calcium in the lignin acts as a microbial food while the lignin sulphonate acts as a chelating agent, (large, organic molecules that are used to envelop highly-reactive trace metal ions). The purpose of chelates is to incorporate metal ions like magnesium, boron, and zinc into a soluble but bound form that is capable of supplying nutrients to the plants. As the chelate breaks down, the metal ion micronutrients are slowly released into the soil in a bioavailable form that may then be taken up by the plant.  The presence of Sulfate has been known to enhance the natural aromas and flavors of plants.  Directions for Use Shake well before use. Soil Application: During vegetative growth and bloom phase, mix 1 TBS. per gallon of water, adjust pH to 6.4-6.8 and apply every time you feed.
