  • Sale -8% Grotek Green Line Synergy, 800 grams Grotek

    Grotek Green Line Synergy

    What is Synergy Synergy™ is a water-soluble powder that contains fungi that helps plants achieve explosive root development and overall growth all the way to harvest. 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.
