  • 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. These functions are important for having a healthy rhizosphere and an efficiently operating planting medium. Ecozen contains enzyme complexes that transform some accumulated or precipitated salts into usable plant nutrients. 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

Arbucular Mycorrhizal Fungi (AMF) stimulates growth and productivity in the majority of plants on our planet and they also directly help improve soil conditions.Key features: A mycorrhizae that works with fertilizers Industry leading colonization Directly impacts plant growth and yield A closer look:The variety of mycorrhizae found in Synergy™ is particularly effective in intensive agriculture when using fertilizers. Not all Mycorrhizae have constant positive results with crops. This is due to a lack of colonization, which can be impacted by the use of any fertilizer. This particular strain adapts to and tolerates saline (EC) environments found in intensive agriculture far better than glomus intraradices and glomus mosseae. Under these conditions, Synergy™ shines with rapid colonization and improved impact on plants and soil structures.Directions for use:Avoid contact with eyes, skin and clothing.Wash hands after use. Store in a cool, dark location with lid secured between uses. Transplant – Add 1g per 4L of potting soil. Apply 5 days after transplant. Mixing potting soil with Grotek Organics™ Black Pearl™ can increase benefits. Root Drench – Add 1g per 4L of potting soil. Apply every 10-14 days until harvest (ensures high contact as roots grow). When used outdoors in true soil, apply 1.5kg/acre (3kg/Ha) a few days after transplant and again 2-3 times during the growing season.Compatible with Grotek Organics™ Root Force™ for added impact. Be sure to mix well in solution. If solution sits in a reservoir agitation is required. Mixing just prior to use ensures best results.

  • Sale -26% Humboldt Nutrients Verde, 1 gal Humboldt Nutrients

    Humboldt Nutrients Verde

    It's Spanish for green. Lush green colors and vigorous growth are what you can expect with Verde. Used as a foliar spray or as a growth catalyst for hydroponic or soil crops, Verde keeps plants healthy throughout their life cycle. Verde is a premium growth supplement with 16% nitrogen, 1% phosphorus, and 2% potassium, as well as calcium, iron, magnesium and other vital elements. This is a great blend for plants experiencing periods of accelerated growth. Some competing nutrient lines offer a (16-0-0) formula as a one-part grow fertilizer. This is wasteful and deceiving. Nitrogen alone cannot provide any plant with the proper nutrition for a healthy crop, so competing lines will have you buy separate products to supplement calcium and magnesium. Verde contains every element necessary for a true growth supplement, increasing the rate of chemical reactions which facilitate plant growth. Accessible nitrogen is the key to a plant having a strong and vibrant internal structure. A robust internal structure means a healthy immune system, a necessity for a plant to thrive and produce high quality crops. Verde is a blend that contains high quality, cold pressed Ascophyllum nodosum seaweed, humic acid and pure Yucca extract. This unique product increases root, stem and stalk structure, while boosting chlorophyll levels and protecting the health of your plant. Use Verde in conjunction with Humboldt Nutrients base nutrients and additives for vigorous growth. This is the useful and balanced nitrogen additive you have been searching for. DIRECTIONS:  WE DO NOT RECOMMEND USING VERDE IN RECIRCULATING SYSTEMS. Hydroponic Application Rate: 1-5 ml per gallon of water in reservoir. General Application Rate: 1-5 ml per gallon of water or nutrient solution. Foliar Application Rate: Apply at a rate of 5-10 ml per gallon of finished spray solution. DERIVED FROM: Urea, Ascophyllum nodosum seaweed, phosphoric acid, sulfate of potash, zinc oxide, iron oxide and magnesium oxide.
