DL cocktail is a combination of precisely targeted hormonal triggers that increases flowering sites and overall harvest weight. DL cocktail employs the latest in plant hormone technology, bonding essential phytochemical triggers with a carrier. This allows us to control the hormonal response with great accuracy which in turn allows us to limit quality degradation while pushing extreme weight gain. Use Crystal Cocktail to increase your yield without increasing light or plant site. Coco/Soil/Potting Mix: When plants reach the required height treat with DL Cocktail at 1-2ml/L with every feed for 7 days. For a hardening effect use DL Cocktail for the last 7 days before flushing at 1-2ml/L. Recirculating: When plants reach the required height treat with Crystal Cocktail for 7 days. To induce a hardening effect, dose again for week 6-7. General Usage Tips: In run to waste systems ensure 20-30% run off at each feed. Adequate run off flushes old nutrients out of your growing medium, allowing new plan available ones to take their place. DL Cocktail induces aggressive flowering. This feeding technique helps ensure your plant has the best nutrients available to support this development. This product used to be OG Flower Hardener, and is now relabeled under DL Cocktail. The product is exactly the same, just a label change.
