"Flushing" your cannabis plants.
A term many new growers may not be familiar with. This method is used for the purpose of enhancing flavour and to acquire a smooth smoke. Most growers will start to flush around two weeks before harvest. When you start flushing, be sure to stop all feeding to your plants and stick to water only.
This technique is done by excessively watering your plants, which will force the cannabis to use all the nutrients stored within itself. Once your plants have been flushed from all the salts and nutrients, you are ready to harvest your garden with a proper dry and cure to follow, allowing all your buds to fully express themselves.
