    Winter Frost has ethylene precursors that you only use for 1 week, starting about 3 weeks from harvest. Do not use it sooner as it will start the ripening phase that prevents chlorophyll production and other important processes. It can be mixed in a reservoir with your normal feed. It’s most beneficial use case is for long flowering plants that are slow to mature. Something that ripens in 8 weeks or less doesn’t really need the push. It’s usage rate is fairly low so it’s not going to break the bank as a supplement.
