A word you might hear tossed around in those conversations is “flipping”.
If you’ve never heard this term in reference to gardening, you might think it could have something to do with flipping plants upside down for some reason. At least, that’s how I thought of it when I first heard the term.
In reality, flipping is much simpler, and less idiotic than my interpretation. Plants thrive on certain light cycles, and flipping is essential to maintaining this cycle.
Some plants like about 18-24 hours of light a day when they are in their vegetative stages. This allows them to absorb as much light and nutrients during the day to make them stronger and more resilient.
