Harvesting indoor crops typically involves two different techniques. The first technique is hand-harvesting, which involves carefully removing each individual crop from the plant. This technique works best with smaller plants such as herbs and vegetables, but can also be used on larger crops like fruits and nuts if the plant is small enough to manage. The second technique is machine harvesting, which utilizes specialized equipment to quickly harvest an entire crop in one pass. This method requires more upfront investment than hand-harvesting, but it saves time and energy in the long run by allowing for quicker harvesting of large areas of crops at once.
