Many growers do everything right until harvest time. Many harvest too early, they only look at the brown hairs of the flower. A better method is to use microscopes to check whether most of the resin crystals are milky. This is the optimal harvest time.

• A few plants can be harvested loosely by hand with harvest scissors
  
  
• From 15-20 plants a Tumble Trimmer or a Master Trimmer Pocket is not a bad investment
  
  
• For larger harvests, Master Trimmer or Greenbroz harvesters are a good way to process a harvest efficiently and without much effort. The difference between these two manufacturers is that Master Trimmers process the flowers fresh and Greenbroz machines dry.

All harvesting methods produce trim waste, small leaves and flowers that can be further processed. There are 3 different methods:

• Dry extraction using pollinators from Top Zeef
  
  
• Wet extraction with extractor bags, water and ice, the best way is with a bubbleator
  
  
• Gas extraction with butane gas or dimethyl ether
  
  
• Rosin extraction, extraction by pressure and heat
